Calibration
For best results, calibrate the scale at regular intervals.
(Calibration weights are not supplied with the scale.)
Use extreme care when handling calibration weights as they are very
heavy. Improper lifting methods or misuse of calibration weights may
result in personal injury. Multiple weights may be used to equal the
required calibration weight.
1. Allow the scale to warm up and stabilize for a least two minutes before
commencing the calibration procedure.
2. To select the weighing unit to be used for calibration, press the UNITS Cal
button until the correct unit is displayed.
NOTE: The calibration process can be stopped at any time by pressing the
UNITS Cal button or by turning the scale off. The correct span calibration
weights will need to be available before starting the calibration (see
specification table). Calibration is unavailable in Dynamic Weighing Mode.
