5.0 Scale Calibration
Before you can calibrate the scale, verify and set all scale parameters which are noted in “Indicator Installation 
and Configuration” on page 7.
Remove the configuration/calibration jumper (see page 8). Turn the scale on. While StArt is displayed, press and 
hold both the 
Kg-Lb key and the REWEIGH keys until CAL is displayed. 
To do a calibration on the scale, the scale must be turned off. 
NOTE: The calibration weight must be no less than 60 lb (28 kg) and no more than 300 lb (135 kg).
