Calibration Guide
PREPARATION
CKW Indicators have two calibration processes: Span and Linearity.
Ensure that the scale is level, stable, and undisturbed during calibration.
(Otherwise the process could fail.)
Allow Indicator to warm up for five minutes after stabilizing to room temperature.
Use suitable calibration masses (available from Ohaus).
Exact weight value depends on model. Follow prompts for indicated values to use.
(Weight values here are examples only.)
Set the scale's calibration units to match the calibration masses: in the Setup Menu,
choose either kilograms or pounds.
If the scale is set to Legal for Trade operation, a seal must be broken to unlock it.
(See the Instruction Manual.)
Note: To cancel calibration, press
