CAUTION:
IF THE SCALE WILL BE SOLD TO AN APPLICATION THAT IS LEGAL
FOR TRADE. IT IS HIGHLY RECOMMEND SETTING THE JUMPER TO
CAL-LOCK POSITION TO DISABLE THE CALIBRATION AND INTERNAL
FUNCTION SETTING.

10~14 30~60 at 33% of Max. R1, R2 150
READING OFFSET VALUE
1 Turn scale off
2 Remove all load from platter
3 Enter F3 and read the offset value
READING SPAN VALUE
1 Turn scale off
2 Remove all load from platter
3 Enter F1
4 Press ZERO
5 Apply load to platter. Span value according to load applied
will be displayed.
HOW TO ADJUST OFFSET VALUE
In case the offset value is out of range, change the resistors R1,R2
to obtain correct offset value.
HOW TO ADJUST SPAN VALUE
The span value is controlled by the resistor locating at R9, standard
resistor value of R9 is listed on the above table. If the required
span value is not attained, then change R9 resistor according to either
case below:
Span value too low: Decrease the resistance of R9.
Span value too high: Increase the resistance of R9.
