    Rev O, January, 2008 How to Calibrate the PW800 The following details the calibration procedure for the PW800 scale. There are eight parameters that can be set without moving the calibration blocking switch, followed by five more parameters and calibration that require the calibration blocking switch be in the 'CAL' position.
