LaMotte Spin Touch: Troubleshooting with the Meter Check Disk | Check Calibration Procedure

CALIBRATION OPERATIONS The Meter Check Disk (MCD) is used to perform two calibration operations – Check Calibration and Start Calibration. The Start Calibration procedure should only be performed if the meter fails the Check Calibration procedure.

Check Calibration: Meters are calibrated at the time of manufacture. However, it is possible for the calibration settings to be lost due to power anomalies or other circumstances. The Meter Check Disk is used in the Check Calibration procedure to determine whether the alignment of the hub and disk are correct. For some meters, it also evaluates the brightness of the individual LEDs.
