5 Calibration - Using an External Calibration Weight
Calibration is generally required when the weighing machine is initially installed or if the weighing
machine is moved to a substantial distance from the original location. 30 minutes of warming up of the
scale is always needed before initial calibration.
A reminder when operating our larger capacity scales:
!
The WB series are calibrated at the factory. Usually no recalibration is necessary unless major
inaccuracies are observed. If calibration is deemed necessary, an appropriate test weight of at
least 2/3 of the full capacity of the scale should be used to obtain accurate weighing.
Calibration procedure:
− Press and hold ZERO key and then press ON/OFF key to turn on the scale, the display will show
CAPu= !
− Press HOLD key, display will show CAP, press HOLD key again, display shows CALu=, press
UNIT key to select calibration unit KG or LB, a triangle icon will display to indicate KG or LB,
press HOLD key to confirm, it will show CALu= again. !
− Press HOLD key again, the display will show CAL, press UNIT key to set calibration weight,
display will show XXXXX with a flashing digit, press UNIT key to move the flashing digit to right,
press ZERO key to increase the value of the flashing digit, press HOLD key to confirm, it will
show CAL again. (We recommend a calibration weight at least 2/3 of the full capacity to get an
accurate weighing) !
− Press PRINT key, display will show CAL and then the AD value, press UNIT key when the stable
indicator displayed, it will show the flashing calibration weight, !
− Place the known test weight on the platform, press UNIT key after stable indicator displayed, it
will show ------, and then the AD value, now the calibration is finished. !
− Turn off the scale, remove the test weight from the platform. !
− Press ON/OFF key to turn the scale on to test if the weighing is accurate, if not, repeat above
steps. !
