Equipment Check
1. Turn sensitivity dial fully clockwise.
Notes: 1. Clockwise rotation of sensitivity dial turns meter on and
increases sensitivity.
2. Always set dial to highest sensitivity position, then
decrease if necessary.
2. Depress the Battery Test button to test the battery and main
circuitry (does not test the cable or probe).
3. Submerse the probe in tap water. This completes the circuit
and activates the buzzer and light.

Water Level Measurements
1. The zero measurement point on both P4 and P10 Probes is
near the tip.
2. For ease of operation the Tape Guide can be used to support
the Water Level Meter. (See diagram below).
3. Feed the cable into the well. The light and buzzer activate
when the probe tip enters water. To ensure accuracy, lower
and raise the probe a few times and then record the depth
measurement from the cable at the top of the well.
4. When using the Tape Guide, the measuring point is offset
from the top of casing. To adjust your measurements to the
top of the casing, simply subtract the amount indicated on
the front of the Tape Guide (ie 6 cm or 2/10 ft)
The Tape Guide
Measurement Point
Insert Water Level
Meter leg through
hole
Fit onto well casing
The Tape Guide has been designed to:
• Improve accuracy when reading water levels,
• Easily obtain repeatable measurements,
• Prevent cable damage on well casing,
• Allow the cable and probe to hang straight from the side
of the well.
1. Fit the small end of the Tape Guide onto the edge of well
casing 2" dia. or larger.
2. For small reels, insert the leg of the Water Level Meter into
the hole on the Tape Guide and rest the Water Level Meter
on the side of the well casing. (See diagram at right).
3. To store the Tape Guide after taking water level
measurements, simply clip it onto the support bracket
located on the back of the Water Level Meter.
Tape Guide:
prevents cable from
scraping the top
edge of well casing
Water Level Meter:
anchored to the well
casing with the tape guide
for stable operation (small
reels only).

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 warm water.
Do not submerge the reel.
3. Use of a Water Level Meter Carrying Bag adds to the service
life of the meter.
4. Use of the Tape Guide adds to the life of the cable.
Replacement Parts
The following parts can be provided should components
become lost or damaged.
1. Splice kits
2. Lights, dials, etc.
3. Reels and/or faceplates
4 Replacement cable with probe (complete)
5. Assembled probes on 10 ft or 3 m lengths of cable
6. Weights
Battery Replacement
• Battery type - alkaline, 9 volt.
1. The battery is housed in a convenient battery drawer located
in the faceplate of the Water Level Meter.
2. To replace the battery, simply press the drawer in, lift, then
pull.
3. The battery drawer should slide out of the faceplate enough
to pull it out.
4. Note the polarity. The positive (+) terminal should be
towards the small notch in the end of the drawer. Place new
battery in the drawer and slide it back into the faceplate.
