Load Cell Configuration
All load cells installed on the mixer MUST have identical ratios of sensitivity to
capacity (sensitivity/capacity). This is true if all load cells are of the same model
and should be checked
otherwise.
Using the calibration number from an existing indicator:
Find and note the calibration number of your existing indicator as the Rated Capacity
(lb),
and use 0.40 mV/V as the Sensitivity. Please consult the existing indicator's user manual
or
visit the agrimatics.com
support page
for help retrieving the calibration number on some indicators.
In all other cases:
Read and note the Sensitivity (Rated Output) and Rated Capacity (Rated Load) from any
one load cell on the mixer. Multiply the Rated Capacity by the TOTAL number of load
cells
on the mixer.If specifications are unavailable, a good starting point is a
Sensitivity
of 0.40 mV/V and a Rated Capacity of 8000 lb multiplied by the TOTAL number of load cells on
the mixer.
Configuration
1. Ensure the Libra TMR device and app are paired and connected.
2. Ensure units (lb, kg) are set to those of the Rated Capacity found previously.
3. Select the Device tab and enter the Sensitivity and Rated Capacity noted
previously.
4. Enter the Calibration Factor as 1.0.
5. Tap Save Settings.
Calibration
1. Ensure the Libra TMR device and app are paired and connected.
2. Ensure the mixer is empty and on level ground.
3. Select the Display tab and tap Tare.
4. Load the mixer with a known weight and note the reading from the large display.
Larger weights provide higher precision.
5. Select the Device tab and enter the known weight as the Certified Reading, and
enter the noted amount as the Mixer Reading.
6. Tap Calculate to determine a new Calibration Factor.
7. Tap Save Settings.
Firmware
Just as the Libra TMR app can be updated through the App Store, the software that
runs on
the Libra TMR hardware device can also be updated. To check the
availability of new
firmware for the device, tap Update Firmware. If a new version is available, the
app
will guide you through the update process.
Restoring the Device
In the unlikely event that you need to restore the firmware to factory defaults,
tap Restore Device.
Sending Diagnostics
Tapping Send Diagnostics will send Agrimatics an email with all weight measurements
collected
by the Libra TMR app. This data will help us tune future versions of the app, and
help diagnose any issues to ensure you
experience the best performance possible. When sending diagnostics, please add some
descriptive notes to the email to ensure that we understand the problem or the
specific need.
