  • Do not attempt to separate the components of the Meter Check Disk (Code 1705). The Meter Check 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.


Range Check Procedure

The Meter Check Disk is used to verify the performance of a meter. It is not used to recalibrate the meter. Meters are calibrated at the time of manufacture. The meter is performing satisfactorily if readings using the Meter Check Disk are within the ranges provided on the Meter Check Disk pouch.

Range specifications are specific to the disk identified by the serial number on the pouch. The range specifications will vary from disk to disk. The exact readings from a specific disk may vary from meter to meter.


  1. Follow the Cleaning procedure BELOW to clean the light chamber and optic lenses.
  2. Tap the Disk Icon to select Disk Series.
  3. Tap MCD to select Meter Check Disk.
  4. Tap the Water Drop Icon to return to the test screen.
  5. Remove the Meter Check Disk from the foil pouch. DO NOT remove the black cover from the disk.
  6. Insert the Meter Check Disk. Close the lid.
  7. Tap the Start Test Icon to start test.
  8. Results will be displayed.
  9. Compare the results on the display to the values on the chart shown on the pouch.
  10. Replace the Meter Check Disk in the foil pouch for storage.


If the results are not within the range shown on the pouch, contact tech service.


Alignment Procedure

The Meter Check Disk is inserted in the meter and Calibration is chosen from the Settings Menu to perform an angle calibration which checks the alignment of the hub and disk. The results are analyzed and reported as Pass or Fail. If the measurements pass, the settings will be saved. If the analysis fails, contact tech support.


  1. Follow the Cleaning procedure BELOW to clean the light chamber and optic lenses.
  2. Tap the Gear Icon to go to Settings.
  3. Tap Calibration.
  4. Remove the Meter Check Disk from the foil pouch. DO NOT remove the black cover from the disk.
  5. Insert the Meter Check Disk. Close the lid.
  6. Tap Start to begin the meter check procedure.

    If the meter is not performing satisfactorily, “Angle Calibration Unsuccessful. Contact Tech Support.” will be displayed.
  8. Tap the Water Drop Icon to return to the Testing Menu and resume testing.



  • Do not touch top or bottom of disk. Handle disk by the edge.
  • Do not fill disk while in the meter. Fill disk on clean, dry surface.
  • Fill the disk on a dark surface to more easily see the sample water.
  • The disk should not contain any large air bubbles. Air bubbles will result in erroneous results.
  • Always use the disk cover.
  • Only the Universal Disk Cover (Code 1719) can be used with the WaterLink® Spin Touch® DW.
  • Empty syringe of old sample before filling with next sample.
  • Remove filled disk from meter after testing. Do not travel with filled disks in meter. They may leak.




The optical system of the WaterLink® Spin Touch® DW must be kept clean and dry for optimal performance. Dry the disk with a lint-free wipe before placing it into the chamber to avoid introducing moisture. For best results, store the instrument in an area that is dry and free from aggressive chemical vapors. Clean the exterior housing with a damp, lint-free cloth. Do not allow water to enter the light chamber or any other parts of the meter. To clean the light chamber and optic lenses, point a can of compressed air into the light chamber and the lid and blow the pressurized air into the light chamber and lid. Focus the pressurized air around the LEDs which are the small round lenses positioned at 2:00, 4:00, 6:00, 8:00, 10:00 and 12:00 in the lid. The photodiodes are located on the bottom of the chamber around the hub. This area must be kept clean and dry. Use a cotton swab dampened with Windex® window cleaner to gently swab the LED and photodiode lenses. Do not use alcohol; it will leave a thin residue over the optics when dry.

Remove smudges due to routine use from the touchscreen with the Cloth Wipe (Code 3580-WIPE). Use a cloth dampened with alcohol for more thorough cleaning when necessary. Do not use Windex® window cleaner, or similar cleaners, on the touchscreen.
