CALIBRATION
Calibration may be required when the scale is rst set up for use, or if the scale is moved to a dierent altitude or new location. 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 can occur.
How to calibrate: you must have an accurate 75kg weight in order to calibrate
1. Make sure the scale is turned o. Press and hold [ZERO] (do not release) and turn on the scale, release when the display shows
the A/D value (a series of random numbers).
2. Press [UNIT] , the display will show the “CAL” and then the correct calibration weight “75.00”.
3. Place the correct calibration weight on the platform and wait 5 seconds. The display will show ”PASS” and then return to normal
weighing mode.
