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.
