Gravity adjustment
WARNING:
This parameter should ONLY be used at the scale that will be initially verified in two stages by
gravity adjustment in legal metrologic applications.
The gravity acceleration values of the place of the calibration and of the place of the usage are entered in this
parameter.
1. Press
key to access this parameter.
2. [ 624 GRAVITY CAL : 9.80255] prompt seen. Enter the gravity acceleration value of the calibration
place. Confirm with
key.
3. [ 625 GRAVITY USAG : 9.80255] prompt seen after pressing
key. Enter the gravity acceleration
value of the place of the usage.
4. Confirm with
key.
Calibration coefficients
Calibration coefficients are calculated after calibration and saved to the memory for usage until next
calibration. Note these coefficients to use them in case of calibration lost. Changing them slightly improves
the scale accuracy without recalibration. Entering these values to another indicator may cause slightly
reducing the weighing accuracy due to offset differences between two analogue digital circuits.
