Calibration
As the gravity value is not the same at every location on earth. To achieve best accuracy, the scale is
highly recommended to be calibrated in compliance with the gravity at the place of use. This calibration
process must be carried out for the first time of use, after each change of location as well as in case of
environment temperature change. To receive accurate measuring values, it is also recommended to
calibrate the scale periodically in weighing operation.
The calibration should be made with the recommended calibration weigh
t
(see specification).
Procedure for calibration:
Observe stable environmental conditions. A warming up time of 30 minutes is required for stabilization.
► Turn on the scale by pressing the
ON/OFF
key.
► Press
SET/TARE
key and keep it pressed, until [
CAL]
appears in the display for few seconds.
After that the adjustment weight (see specification) appears and flashes in the display.
► Place the adjustment weight on the center of the platform.
► Now press the
SET/TARE
key. Short time later [
CAL F]
appears, then returns automatically to
the normal weighing mode. Readings of the adjustment weight appear in the display.
An error during adjustment or the use of an incorrect adjustment weight will result in an error
message
[
CAL E]
. Repeat adjustment.
Keep the adjustment weight close to the scale. Daily control of the weighing exactness is recommended
for quality-relevant applications.
Auto-Off
For battery operation the scale has an automatic switch-off function which can be activated or
deactivated in the menu. Procedures as follows:
Turn on scale using the
ON/OFF
key and wait for the zero display.
Press and hold the
FUNCTION
key until
[UNIT]
appears on the display.
Press the
UNIT/COUNT
key or
HOLD/PRINT
key repeatedly until
[ AF ]
appears.
Confirm by pressing the
SET/TARE
key.
Use the
UNIT/COUNT
key or
HOLD/PRINT
key to choose between the following settings:
1. [AF on]:
To save battery power, the scale switches off automatically if 3 minutes without
weighing.
2.
[AF off]:
Switch-off function deactivated.
Use the
SET/TARE
key to confirm selected setting. The scale returns to weighing mode.
