SETUP AND CALIBRATION
Your scale was calibrated at the factory and should not require adjustment. In the event that it
should need recalibration, the following describes the calibration procedure. A qualified
technician should perform this procedure to maintain the scale’s high degree of accuracy.
Before beginning calibration, the following equipment is required:
30 lb Calibrated test weight
3/16 slotted screwdriver (to remove calibration sealing screw)
A small non-metallic tool (to depress calibration switch)
To enter the setup and calibration mode:
1. With the power off, remove the Calibration Access Screw on the lower left corner of the
rear panel, see Figure No.7.
2. With the screw removed, insert a small non-metallic tool into the screw hole and press and
hold the calibration switch.
3. Press the ON key.
4. The display will show LQW. The indicator is now ready for setup and calibration.
