2. Phillips or Robertson Screwdriver
3. Wire Cutters (only required for Mk1 Water Level Meters –
see photo below)
4. Pliers (only required for Mk1 Water Level Meters –
see photo below))
Instructions
1. Place the reel on a flat surface, with the faceplate up.
Remove the battery from the Meter.
Note: The battery is located inside the reel hub of a 102M Water Level
Meter. Remove it in step 2.
2. Use the screwdriver to undo the three screws holding the
faceplate to the hub. Remove the faceplate.
3. If this is a Mk1 Water Level Meter, disconnect the Molex
connector that connects the circuit board to the tape/cable.
If this is a Mk2 Water Level Meter, press down on the white
terminals of the push-release fittings on the circuit board
and pull out to remove the tape/cable leads.

4. To connect the new faceplate with electronics, connect the
tape/cable to the new circuit board assembly:
a) If this is a Mk2 Water Level Meter, press down
on the white terminals on the circuit board and insert
the tape/cable leads. Release the terminals and the
leads should be secured.
For 101 Water Level Meter, the lead on the bottom of
the tape (numbers facing up) is inserted into the
terminal with a white square below it on the circuit
board (see next page for images).
For 102 Water Level
inserted into the terminal with a square etched
below it on the circuit board. The positive lead has
the pin connected to insulated wire, the negative pin is
connected to the braided wire.
b) If this is a Mk1 Water Level Meter, with a Molex
connector on the tape/cable leads, remove the Molex
connector by pushing out the two pins. Cut each pin
in half (see image on next page for correct location).
Use pliers to flatten the remainder of the pins against
the tape/cable lead, so it fits easily into the terminals
on the circuit board. Connect each tape/cable lead to
the new circuit board assembly, as described above in
step a.
