Model 102M Mini Water Level Indicator Operating Instructions

Routine Care

  1. After the depth to water has been recorded, the cable should be carefully rewound onto the reel, the probe wiped dry and placed into the probe holder.
  2. The probe, weights, cable and reel can be wiped clean with phosphate free (non-abrasive) detergent and water. Do not submerge the reel.


Battery Replacement

  1. The battery is housed within the faceplate of the reel.
  2. Using a Phillips screwdriver, remove the three screws on the faceplate.
  3. Carefully remove the faceplate so as to not unwind the cable. Note that there is an elastic band keeping everything together in the faceplate.
  4. While leaving the elastic band in place, replace the battery.
  5. Carefully place the faceplate back onto the hub and line up the holes.
  6. Notes:

    Before screwing the faceplate back onto the hub, make sure no wires are outside the hub.

  7. Once the screws have been tightened and the faceplate is secure, test the water level meter.
