Important notes and first steps (this is an intermediate manual replacement)…

  • Before you start off into your LS3  journey!
    You should first reset /calibrate the absolute zero of your LineScale:
    – place the LS3 on a flat, even surface (table)
    – activate ABS mode (if in REL mode, long-press ZERO to switch to ABS mode) 
    – enter the service menu, and click ZERO on the first item “Set absolute zero”
    – select “Yes” with the arrow keys, and press ZERO
    – the LS3 will jump back to the service menu… press PWR to exit to main menu
    – now long-press PWR to switch the LS3 off, and power it back on
    – it should now show a constant straight 0.00 when on the table
  • 10/40Hz and 640/1280Hz scan rates:
    Please note that when Bluetooth is connected (BT symbol inverted), the LS3 will refuse to switch to 640/1280Hz.
    This is because BT can not transmit these speeds reliably, therefore they are blocked.
    To switch to 640/1280 you need to either disconnect the smartphone app, or simply “kill” the app and then reboot your LS3.
    You can however run on-board logging (10-40Hz), and have a BT connection to your phone to monitor things and/or also run a log in the app.
    App and on-board logging settings are independent of each other. 
  • Auto Power Off:
    Auto power off is inactive by default. You can activate this in the “MENU / User Settings / Auto power off” setting.
    There you can define an auto power off delay from 1 Min. to 60 Min.
    The auto power off will kick in when no button is pressed or no load change has occurred within the defined time span.
  • Battery management:
    When battery power is very low, the LS3 will power down itself to avoid a total battery power drain!
    When battery power drops to a critical level (around 3.0V) the LS3 will power off right after showing the boot screen.
    This avoids a battery deep discharge, and ensures that no on-board logs will ever be lost, by always having enough power to keep them alive.
    Note: a critical battery level can only occur when you let battery drain in the MENU, where the power management features are disabled.
  • The “battery symbol”: When charging it will be animated with a flash inside. The animation stops when the battery is full!
  • A note about “Start trigger” and “Stop trigger” settings:
    Whenever you set the stop-trigger above the start-trigger the LOG will be ended immediately.
    This is because the stop-trigger will stop a log whenever the load is below the threshold. 
  • How to access the on-board logs:
    The stored logs can currently be accessed by plugging in the included flash-drive and then download the files to your computer.
    Unfortunately we are a bit behind the schedule with the LS3-Pro-Software development.
    This software will allow direct log access (and live USB high speed logging with up to 1280Hz).
    For now please up/download the logs via USB flash drive and evaluate them via spread sheet software.
  • IMPORTANT NOTE about connectors!
    If you need precise load readings, take good care to not attach any connectors to the LS3 which apply torsion force to the load eyes!
    These include e.g.: Girth hitch, clove hitch, any “high grip” textile material such as load slings, thick ropes, etc.
    Also, any not perfectly fitting metal connector might apply torsion to the load eye and distort the reading.
    In essence the LS3 may not see any “bending force” in lateral direction to ensure precise readings!
    I will upload some images soon to better illustrate the issue. If you have questions, don’t hesitate to contact us.
  • A note about “Max. log rec time”:
    When you select a rec-time that exceeds the max storable size for one log-slot in the current scan rate, the system will reset it to the max. time for that scan rate.
    The same applies to toggling through the log speeds when a rec-time has been defined.
    E.g. you set 600 seconds (10 Minutes) @ 40 Hz. Then you toggle through the speed. You will notice the rec-time to be adjusted (reduced) to 30 sec @ 640Hz, and 15 sec @1280Hz. This is because each separate log can’t be any longer than this in the higher scan rates. See details about the max log size in the following…
  • Detailed list of log space, log time, logging time, max rec. time, max pre-capture time

    “Max. log rec. time” & “Min. log rec. time” / “Pre-capture rec. time” setting per log @ scan rate:
    – 10Hz: 1920 sec. (32 min.) / 384 sec. (6 min.)
    – 40Hz: 480 sec. (8 min.) / 96 sec. (1.5 min.)
    – 640Hz: 30 / 6 sec.
    – 1280Hz: 15 / 3 sec.

    Each of these log settings is saved separately for each of the four speed settings!
    (so if you set different times for different speeds, and you toggle the speed, the respective setting for that speed is loaded)

    Having space for 100 such log files in onboard memory, this adds up to 2.3 million data points until LS3 memory is full.
    Thats a total on-board log time (incl. max. pre-capture time) of:
    – @10Hz: ca. 63 hours
    – @40 Hz: ca. 16 hours
    – @640Hz: ca. 1 hour
    – @1280Hz: ca. 1/2 hour

 

LineScale App

 

Both the Android and iOS app are still in development, or better said, still being improved.
We will always make the latest versions available for you here.
Note: the LS2 app will work for both units, LS2 and LS3!

The LineScale iOS app is available for download in the Apple Appstore. 
Requirement: iOS 12.0 or later.

Appstore link: download the lineScale iOS app (current version 1.1 from July 2020).
Or simply search for “Linescale” in the Appstore.
Grant “File access” (to save logs) and “Bluetooth access” during installation.

Please note: before you remove a beta version you had installed on your phone over “Testflight”, please export any logs you want to keep, because these will also be deleted when you remove the beta app 😉

Click on this link to download the Android App release 1.2 (Sept. 16. 2020)
Requirement: Android 5.1.1 (Lollipop) or later.
NOTE: fully uninstall any earlier beta version before installing version 1.1!!!
Grant “File access” (to save logs) and “Bluetooth access” during installation.
If you use “Google Advanced Protection” on your device you can’t install apps from websites other than the Google Play Store. We are working on uploading to the Play Store and expect the lineScale app to be available there in the next final version 1.2 in a few weeks.

App quick start guide:
• install app
• power up lineScale
• start app
• Android: press “settings” (gear symbol), and “Connect lineScale”
• iOS: press Bluetooth symbol 
• select your lineScale from the list
• return to app main screen
Now the bluetooth symbol on the lineScale shows and you’re connected 😀

If with Android you get the message “lineScale not found” despite an available unconnected lineScale nearby, please enable “Location based services” in your phone settings! The Android Bluetooth API is somehow linked to this service in some Android versions. LineScale app does not do location tracking though! 

Note: you can NOT (and must not) connect the lineScale via bluetooth pairing!
All bluetooth lineScale management is done through the app. 

Once connected, the app will auto-connect to the last known lineScale as soon as it’s available.
You can connect to another lineScale (switch scales) via the settings menu.

LineScale-3 Firmware

 

The current factory installed firmware is:

  • V1.827 for all units shipped up to Nov. 17th.
  • W2.211 for all units shipped from Nov. 18th.

Dec. 1st 2021

Firmware V2.320 includes (additionally to 2.211 – see history below)

  • New icons “battery”, “rec” & “bluetooth”, and the current load value are displayed on the “lock screen” 😀
  • Exit the MENU to main screen with a press of the PWR button (also exits the Sub-Menu & “Escapes” an item edit).
  • “Auto power off” is disabled when:
    – “LOG” is set to “ON” or;
    – a log is recording or;
    – a Bluetooth connection is active (inverted BT symbol) or;
    – the ABS load is > 0.05 kN.
  • The defined “Max rec”, “Min rec”, and “Pre-capture” values are now stored for each of the four speed modes!
  • New menu item “Scan rate” in the “Log” menu so you can switch the speed in the menu while defining all your log settings for each speed.
  • “Max rec”, “Min rec”, and “Pre-capture” is reduced to the scan-rate max value when a value is entered greater than the max allowed.
    (so to set the max value you simply enter a “1” as first digit and confirm all others)
    (you will find the max settings in Detailed list of log space above in the section Get Started)
  • Abort/cancel a running “Log Export” by long-pressing the PWR button while export is running.
  • (the currently exporting log will stop export, and be deleted on the flash drive to avoid any corrupt or incomplete files on the drive) 
  • When in PEAK mode, pressing ZERO will reset the peak value only, not the relative zero.
  • When in ABS mode, pressing ZERO will reset the MAX and MIN values.
  • “Peak”, “MAX” and “MIN” values are retained when toggling speed and unit.

 

Known minor bugs for V2.320: none significant to date 🤘

  • Insignificant: the “Min log rec time” can be set higher than the “Max log rec time”.
    (should default to max if set higher but totally irrelevant if >= max it’s just inactive)

This V2.320 is the most stable and reliable version to date, therefore: UPDATE asap!
I encourage you to install it if you have a Windows computer with XP or later, and some driver installation experience.

Download the Windows firmware flash utility package here (2.5MB) > does not include firmware file, download below!

If you already have the flash utility, download the current firmware file “LS3_firmware_v2.320.hex” (88kb)

IMPORTANT!!! Study and understand the READ ME FIRST file included in the package before flashing!!!

If you’re updating from V2.100 you should clear the log memory after installing V2.320.
This is to delete the “manually stopped” logs with corrupted file pointer (these can NOT be retrieved). 

 

Firmware V2.400 is already in the works, and will include some additional features and tweaks:

  • Enable 3 “power save” / “lock screen” profiles:
    – P1 = least power save, display large fonts, 1 sec. flash interval
    – P2 = medium power save, medium sized fonts, 2 sec. flash interval
    – P3 = max power save, small sized fonts, 3 sec. flash interval
  • Select one of 3 display refresh rates to avoid display flicker when recording the display in certain light conditions.
  • More date formats (possibly).
  • Menu item to display on screen: QR code & important information from the rear laser label.
  • etc… currently updating…

 

 

LineScale-3 Firmware HISTORY 

 

Nov. 18th 2021
Firmware V2.211 includes
(additionally to 2.200 – see history below)

  • Fixed: The “onboard log is running” messages are revised and error free now.
  • Fixed: The defined “Max log rec. time” is remembered even when a speed change is made.
    (e.g.: you define 300 sec. for 40Hz, toggle to 640Hz (max. = 30 Sec.) over 1280Hz and back to 40Hz, it will still show the 300 sec. you defined before)

 

Known minor bugs for V2.211:

  • The defined “Max log rec. time” is not reduced to the scan-rate max value when a speed change is made.
    (please note the max log times: 10Hz=1920sec., 40Hz=480sec., 640Hz=30sec., 1280Hz=15sec.)
  • Not really a firmware bug but rather this might bug the user when operating the LS3:
    – V2.211 will retain the same user defined “Max log rec. time” for every speed setting
    – This might be confusing because each Hz setting actually has a physical storage max time (see above – “Get started” section)
    – V2.300 will save a user defined “Max log rec time”, “Min log rec time”, and “Pre-capture rec time” for each of the four speed setting.
    – This  will enable you to preset a fixed and saved log time profile for each of the four speed settings!

These minor bugs will be fixed in the soon to come V2.300 (with the speed-log-profiles)!
Aside from these little details the V2.211 is a stable and reliable version.
I encourage you to install it if you have a Windows computer with XP or later, and some driver installation experience.

If you’re updating from V2.100 you should clear the log memory after installing V2.211.
This is to delete the “manually stopped” logs with corrupted file pointer (these can NOT be retrieved). 

 

Nov. 16th 2021
Firmware V2.200-Beta includes:
(additionally to 2.100 – see history below)

  • Fixed: The “memory symbol” is complete and will show number of available log slots. 
  • Fixed: When power off and log is running the question “power off now & discard log”:
    – Answer YES stops log, does NOT save log and switch off!
    – Answer NO returns to main screen.
  • Fixed: “Log running” messages are now unmistakably formulated.
  • Fixed: When manually stopping a log in “Single” mode with the LOG key, log is saved, and LOG is in off mode.
  • Fixed: Menu item “Display power off” in “User settings” is renamed to “Power save & lock”.
  • New: When the “stop log” message is displayed and user does nothing (no button press) for 1 minute,
    the message and operation will be aborted, and LS3 jumps back to the main screen.
  • New: When in MENU and user does nothing (no button press) for 5 minutes, the LS3 jumps back to the main screen.
  • NEW: “button lock” message is displayed in 3 rows (centered on screen), and flash slower (2 sec on, 2 sec off).
  • NEW: In lock screen the “REC” symbol is displayed when an onboard log is being recorded.
  • NEW: In menu “Service” added “Factory reset” item.
    This will delete ALL memory and reset all log and user values to the factory defaults.
    Note: as of today the calibration-values can NOT be reset yet (so please don’t mess with calibration)! 

 

Known minor bugs for V2.200:

  • The “onboard log is running” messages still have some formating errors (cut off words)
  • The “Max log rec. time” is reset to the max log time for the respective speed whenever a speed change is made.
    (10Hz=1920sec., 40Hz=480sec., 640Hz=30sec., 1280Hz=15sec.)

All these minor bugs will be fixed in the soon to come V2.210!
Aside from these little details the V2.200 is a stable and working version (we call it beta due to some little buggies).
I encourage you to install it if you have a Windows computer with XP or later, and some driver installation experience.

If you’re updating from V2.100 we suggest to clear the log memory after installing V2.200.
This is to delete the “manually stopped” logs with corrupted file pointer (these can NOT be retrieved). 

 

Nov. 11th 2021
Firmware V2.100-Beta includes: 

  • New feature to avoid accidental power on (in your bag) and accidental power off:
    When LS3 is off: long press = power ON, and short press = no function
    When LS3 is on: long press = power OFF, and short press = enter MENU
  • New feature: Button lock (this is cool!)
    Press “PWR-ZERO” simultaneously to lock/unlock all buttons.
    The LS3 then switches to display power save mode and flash:
    “Locked! PWR-ZERO to unlock”
    Also note: the V1.827 power save (flashing time) is replaced by auto-button-lock, and
    the buttons are locked automatically upon “power save” threshold.
  • An enhancement to the “memory icon”:
    This icon now displays the available “log slots” instead of the % used slots.
    The LS3 has 100 on-board log slots. Each log takes up one slot (independent of it’s size).
    If you have 10 logs in memory, this icon will display “90”.
  • A new function in the “log menu” to set “single log” or “continuous logging”.
    With “single log” it will stop after one log is run and then switch to “log off” status.
    After you turn “log on” it will again run a single log, etc.
    And “continuous logging” will be as it is with V1.827: continue logging as long as load > trigger.
    This mode is displayed on the main screen with an “S” or “C” beside the memory icon.
  • A new function in the “log menu” to set a “Min. log rec. time”… yes you read right, minimum log time.
    This feature will override the set “Stop trigger” if the log is not at least the defined time length.
  • A new function in the “Service Menu” to reset the LS3 to “Factory default values”.
    Please note: this erases all logs, and does NOT (yet) reset the calibration data!
  • Message pop up (full screen) for button press MENU, SPEED, LOG, UNIT, MODE when logging is running:
    (all of these buttons interrupt and discard a currently running log with V1.827)
    “Onboard logging is running. This operation will stop the log and save the current log status!”
    “Sure to stop and save log now?”
    User interaction: “yes” and “no” selection with the arrow keys and confirm with enter (ZERO).
    The default selection will be “no”, so if user just presses ZERO without arrow selection, LS3 jumps back to main screen.
    Of course logging will continue in the background while this message is displayed!
    It is now virtually impossible to accidentally stop and lose a log… some logs are super valuable!
  • A new feature to manually prematurely stop a running log, save it, and disable on-board logging.
    With V1.827 when a log is running, and you (long) press the LOG button the log stops but it is not saved.
    New: (long) press LOG button to display the above message with “yes/no” selection.
    When “yes” is selected the log is stopped and saved, and the on-board logging is switched off.
  • Only exception to this: the POWER button!
    When running a log and PWR is pressed, the following message will pop up (full screen):
    “Onboard logging is running. Power off will stop the log and NOT save it (DISCARD)!”
    “Sure to power off now?”
    User interaction, default selection, and continue log in background is the same as above.
    The LS3 will NEVER abort a log and discard it without the user confirming this (as long as the battery has power)!!!
    The PWR button option is the only way to stop a log prematurely AND discard the so far recorded data.

 

CAUTION!!! MAJOR BUG for V2.100 discovered Nov. 13th 1500 CET!!!

When stopping (and saving) a log manually, it is displayed in memory (log slots reduced by 1)
but the stopped logs in on-board memory are NOT exported to flash drive!!!
As of now there is no possibility to access these manually stopped logs…

If you have any important “stopped” logs please do not delete memory, and wait for the next firmware version.
Firmware flash does not delete memory, so with this you will most probably be able to export them 😉

 

Known minor bugs for V2.100:

  • “memory symbol” is cut off on the left side (where the charging symbol was).
    This is only when not charging… when charging it is ok.
  • When power off and log is running the question “power off now” answer with YES saves log.
    Answer YES must stop and NOT save log and switch off!
  • “Power off” message last sentence is unclear, change to: “Sure to power off now?”
  • “log running” message last sentence is unclear, change to: “Sure to stop and save log now?”
  • When manually stopping a log in “Single” mode with the LOG key, it stays in “Log on” mode.
  • When the “stop log” message is displayed and user does nothing (no button press) for 1 minute,
    the message and operation will be aborted, and jump back to the main screen.
  • When in MENU and user does nothing (no button press) for 5 minutes, 
    close menu and jump back to the main screen.
  • “button lock” message will be displayed in 3 rows (centered on screen) and flash slower (2 sec on, 2 sec off).
  • Rename “Display power off” in “User settings” to “Power save & lock”.

All these minor bugs will be fixed in the soon to come V2.110!
Aside from these little details the V2.100 is a stable and working version (we call it beta due to the many little buggies).
I encourage you to install it if you have a Windows computer with XP or later, and some driver installation experience.
