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. (See Instruction Manual for details.)
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
or turn the scale off.
