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.
