7.0 CALIBRATION
• Calibration is recommended for best accuracy. It is suggested that the
scale be calibrated when first installed and any time the scale is moved
to a different environment.
• To ensure best accuracy calibrate before use.
• Ensure weights are ready before calibrating, the weight should be of a
known accuracy, for example OIML class M1 or Class 4 of ASTM E617.
• Do not calibrate the scale if no calibration weight is available.
• Calibration can only be accessed if the Calibration function has been
enabled as described in section 6.0.
