6. Calibration
It is recommended to perform only the very first calibration following the function LF 1 in the
Supervisor Menu. To prevent any unintentional change of the scale configuration, all the subsequent
Calibrations should be performed entering the Quick Calibration Menu [ECF].
Both procedures above, must be conducted following the steps on the 6.1 Scale Calibration
Procedure.
6.1. Scale Calibration Procedure
The following procedures assume that the scale has been already properly configured [function LF 2],
including the settings of the Gravitational correction values [function LF 7] and Linearity correction
points [function LF 3].
Perform the linearity procedure only if test weights applied to the scale between the zero and span
calibration points are showing slight inaccuracies, such as ± a few divisions. If large inaccuracies are
recorded, this indicates a possible mechanical problem or possible loadcell failure which linearity
calibration may not be able to correct.
LF-2 CALIBRATION SETTINGS
• Default setting is for calibrating in kg [110001]
• To calibrate in lb set LF2 to [110002]
The calibration steps following the function LF 1 or entering the Calibrations Menu ECF are the same.
For this reason only the ECF is described below.
Before starting, make sure that LF 3 and LF 7 are configured as desired
and test weight equivalent to at least 1/3 of the maximum capacity.
i. When the scale is ON, press and hold the FN(▲) key for 3 seconds;
ECF-1 will be displayed.
ii. Press ON/ZERO/TARE (
↵
) key;
CAL Z will be displayed.
iii. Remove the loads from the pan and press ON/ZERO/TARE (
↵
) key;
iv. Edit the span increasing the numeric value by pressing FN(▲) key
and/or press ON/ZERO/TARE (
↵
) key to move to the next digit;
v. Press ON/ZERO/TARE (
↵
) key to confirm;
vi. When the span value blinks, load the test weight;
vii. Press (ON/ZERO/TARE (
↵
) key to complete and exit the procedure.
