VIII. Calibration

Calibrationandadjustmentareperformedatthefactory.

However,theweighingrangecanshiftslightlyduring

shipping.Also,duetochangesinlocalaccelerationofgravity

aroundtheworld,adjustmentisrecommendedwhenmoving

thescalefromonelocationtoanother.Tocheckcalibration:

1. Placetherequiredcalibrationweightonthescale

andnotethedisplayedvalue.

2. Ifthedisplayedvalueisnotwithinacceptable

tolerance(seechartonnextpage),adjustmentis
