CALIBRATION
When to ca ibrate
Calibration may be required when it is initially installed, if the scale is moved
to a substantial distance.
This is necessary because the weight of a mass in one location is not
necessarily the same in another location. Also, with time and use,
mechanical deviations may occur.
How to ca ibrate
1. Before entering calibration mode, press [ON/OFF] to turn the power on
for 1 minutes.
2. Press [ON/OFF] to turn the power off. Press and keep [UNIT] key then
turn on the scale, the display will show CALU=. Press [UNIT] key to
select setting unit among kg, g, lb and oz, press [ZERO] key to enter to
select calibration weight mode.
3. Press [UNIT] key to move flash digit to right, press [TARE] key to
increase the flash digit. Press [ZERO] key, the display will show CAL
then AD value. Press [UNIT] key, the display will show flashed
calibration weight. Place the shown weight on the platform.
4. Wait for the stable indicator to be displayed then press [UNIT] key, the
display will return to A/D value. Take off calibration weight then turn off
the scale. Now calibration is finished.
5. Press [ON/OFF] to turn on the power again, place the weight on the
platform to make sure whether weighing is correct, if not, repeat steps
2-4.
