Water Level Measurements
- Turn the water level meter on. The zero measurement point on the P10 Probe is near the tip.
- Feed the tape into the well. If a tape guide is used, lay the tape onto the groove on the top. Measurements will be read at the point of the V-notch on the tape guide. Remember to deduct 2/10 ft or 6.0 cm.
- 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 tape at the top of the well.
Solinst Tape Guide (Optional)
- Measurement point (Deduct 2/10 ft or 6.0 cm)
- Fit onto well casing
Equipment Check
- Turn sensitivity dial fully clockwise.
Notes: 1. Clockwise rotation of sensitivity dial turns meter on and increases sensitivity. - Always set dial to highest sensitivity position, then decrease if necessary.
- Depress the Battery Test button to test the battery and main circuitry.
- Submerge the probe in tap water to test the probe. This completes the circuit and activates the buzzer and light.
Routine Care
- After the depth to water has been recorded, the tape should be carefully rewound onto the reel, the probe wiped dry and placed into the probe holder.
- The probe, weights, tape and reel can be wiped clean with phosphate-free (non-abrasive) detergent and water. Do not submerge the reel.
Replacement Parts
The following parts can be provided should components become lost or damaged.
- Lights, dials, etc.
- Reels
- Replacement tape with probe (complete)
- Weights
Battery Replacement
- Battery type – alkaline, 9 volt.
- The battery is housed within the faceplate of the reel.
- Using a Phillips screwdriver, remove the three screws on the faceplate.
- Carefully remove the faceplate so as not to unwind the tape. Note that there is an elastic band keeping everything together in the faceplate.
- While leaving the elastic band in place, replace the battery.
- Carefully place the faceplate back onto the hub and line up the holes.
Note: Before screwing the faceplate back onto the hub, make sure no wires are outside the hub. - Once the screws have been tightened and the faceplate is secure, test the water level meter.
