8.CALIBRATION

‰Calibration of the scale is required when it is initially installed, if it is moved often, or it is moved a substantial distance. Calibration is also necessary in regular scale maintenance due to normal mechanical wear-and-tear, changes in seasonal temperature, humidity, air pressure, etc.

The scale is equipped with gravity compensation, which allows it to be calibrated in one location and then adjusted to match the gravity acceleration at another location where it will be used. But don’t worry about this, as far as you calibrate the scale using a calibration weight and use it at same place.

The scale must perform "warm up" for at least 30 minutes before starting calibration.

8-1. Calibration Procedure Using a Weight

The scale should be powered on at least one-half hour to warm it up before starting the calibration procedure.

1.Remove the calibration switch cover, and press the calibration (CAL) switch. The scale shows “Cal” in the count display.

‰Press the ON/OFF key to exit without calibrating the scale.

‰Press and hold the PRINT key and press the ON/OFF key, then you can also enter calibration mode.

2.Press the ZERO key to enter into zero & span calibration mode.

‰The display flashes the required calibration weight value.
