Unique hanger and tape protector
supports the meter on the casing and
protects the tape from sharp edges
on the well casing.
For best results, calibrate the Conductivity Plµs Meter in
1413 µS/cm solution before each measurement session.
To maximize battery life, the Conductivity Plµs Meter
automatically shuts off after 5 minutes of inactivity. When the
battery is low, “LOW BATT” appears on the display panel. The
meter will continue to operate, but the battery should be changed
as soon as possible.

3. Place the probe in 1,413 µS/cm solution and gently position the
probe so that air bubbles are not trapped under the shroud.
4. Wait approximately 60 seconds for readings to stabilize.
5. Press and hold the calibration button on the control panel
(see Figure 1) until “Please Wait” appears on the display, then
release the button.
6. The meter will calibrate, after which the conductivity and
temperature values will appear on the display panel. The
calibration values are stored until the meter is recalibrated.
Equipment Check
Troubleshooting the Conductivity Plµs
Clean the probe and check for damage
Thoroughly clean the probe with distilled water to minimize any
buildup that could interfere with results.
Q. The unit turns off when the probe contacts water
A. Replace the battery (Figure 1).
General Care of the Conductivity Plµs
Do not scrape the tape against sharp-edged well casing. (Figure 2)
Avoid entanglement with other equipment in boreholes and wells.
Rewind the tape onto the reel after each use.
Clean the probe tip with distilled water.
Do not tap or hit the probe to dislodge dirt or mud. Soak the
probe tip in water to remove trapped dirt.
Inspect the unit for obvious signs of damage. Nicks in the tape that
expose the conductors will cause the tape to malfunction.
Test the Battery
1. Press and release the red power button. A brief message will
appear indicating firmware version. The digital display will then
update with conductivity and temperature readings.
2. If the unit does not turn ON, replace the 9V battery in the battery
box (Figure 1). Make sure the battery is not in backwards.
Test the Probe
1. Turn the unit ON.
2. Allow 4 seconds for the probe to synchronize with the
display panel.
3. Place the probe in tap water. The unit will emit a short audio and
visual indication and the display will update with temperature and
conductivity readings.
4. Remove the probe from the water. The unit will emit an intermittent
3 second audio and visual indication.
Use in the Field
1. Press and release the red power button. A brief message will
appear indicating firmware version. The digital display will then
update with conductivity and temperature readings.
2. Slowly lower the probe until a solid 3 second light and tone
indicate the presence of water.
3. Take note of the marking on the tape. This is the static water level.
4. After 3 seconds the display updates with the temperature and
conductivity values. Allow 60 seconds for the readings to stabilize.
5. Continue to lower the probe and take readings of temperature and
conductivity at the desired depths.
6. When the probe is removed from the water, the unit emits an
intermittent tone while the LED lights.
7. To turn OFF the Conductivity Plµs Meter press and hold the
power button until “Power Off” appears in the digital display.
Calibration of the Conductivity Plµs
For best results, calibrate the Conductivity Plµs Meter
in 1,413 µS/cm solution at 25˚C before starting a
measurement session.
1. Clean the probe with distilled water and allow it to dry.
2. Press the power button to turn the meter on.
Check the tape for cuts that would allow water to enter.
This condition may require service.
Q. The unit does not calibrate properly
A. Gently move the probe to displace air bubbles and
perform calibration.
Ensure that temperature readings are stable before
performing calibration.
Clean the probe tip in distilled water, dry the probe and perform
Q. The unit does not stop sounding in water
A. The unit is designed to work in solutions 100 µS and above.
