This LaMotte Calibration Check Disk is used in the WaterLink Spin Touch with 6 LEDs. Calibration disks are not interchangeable. If you have the older desktop model plugged into a computer, this is not the disk you want.
The Calibration Disk resets the LEDs in the meter so it can read all tests correctly. The Disk consists of a disk with a permanently attached cover. Do not fill the Meter Check Disk with water. Water is not used during the meter check procedure.
The Check Disk is used to perform two calibration operations: Check Calibration and Start Calibration. Meters are calibrated at the time of manufacturer. However, it is possible for the calibration settings to be lost due to power anomalies or other circumstances. The Meter Check Disk is used to check the calibration procedure to determine whether the alignment of the hub and disk is correct.
