101 P2 Water Level Meters
Product Information:
The Model 101 P2 Water Level Meter is a groundwater and surface
water monitoring instrument. It comes in two versions, Mk1 and Mk2.
The Mk1 version has a Molex connector from the faceplate
electronics with a 2 pin connection, and the Mk2 version has
push-release fittings on the circuit board to remove the tape
leads. The product comes with a replacement tape and a new grommet.
Tools and Materials Needed:
- Phillips or Robertson Screwdriver
- Wire Cutters
- 3 Pin Molex Connector Housing
- Jumper Cable (required only for connecting the new tape to Mk1
Model 101 Water Level Meter with Molex connector)
Product Usage Instructions:
- Place the reel on a flat workbench with faceplate up. Undo the
three screws from the faceplate, and slowly remove it from the
reel. - For the Mk1 Model 101 P2, disconnect the Tape Molex Connector
from the Faceplate Molex Connector. For the Mk2 Model 101 P2, press
down on the white terminals of the push-release fittings on the
circuit board to remove the tape leads. - Undo the two screws from the black plastic bridge holding the
tape inside the reel hub, and remove the top piece of the
bridge. - For the Mk1 Model 101 P2, use wire cutters to cut the old Tape
Molex Connector from the old tape. Pull the old tape through the
grommet and remove it from the reel. For the Mk2 Model 101 P2 Water
Level Meters, simply pull the old tape through the grommet and
remove it from the reel. - Feed the new tape through the grommet into the reel hub. Note:
The replacement tape comes with a new grommet. The old grommet may
be replaced with the new one, or left in if not damaged. - For the Mk1 Model 101 P2, by hand, insert the connector pins
into the new Tape Molex Connector housing. The negative connector
pin is inserted into the terminal on the pointed side of the Tape
Molex Connector housing and the positive pin into the middle
terminal (the third terminal is left open). The negative pin is
above the numbers on the tape. - For the Mk2 Model 101 P2 Water Level Meters, cut the pins on
the tape leads at the point shown in the photo. Use pliers to
flatten the pins against the tape leads, so they fit into the
terminals on the circuit board. - Position the tape inside the reel hub with black plastic bridge
over top and refasten the two screws to secure the tape to the
reel. - For the Mk1 Model 101 P2, use the Jumper Cable to connect from
the new 3 Pin Tape Molex Connector to the 2 Pin Faceplate Molex
Connector.
