Rugged Conductivity Meter
Equipment Check
Clean the probe and check for damage
Thoroughly clean the probe with distilled water to
minimize buildup that will interfere with results.
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
Press the red power button shown in Figure 1, 1.
number 3 (see opposite page). A blinking cursor will
appear in the top left-hand corner of the display
panel, Figure 1, number 7.
If the unit does not turn ON, replace the 9 V battery, 2.
Figure 1, number 1.
Test the probe
Turn the unit ON.1.
Allow 4 seconds for the probe to synchronize with 2.
the display panel.
Place the probe in tap water. The unit will emit a 3.
short audio and visual indication and the display will
update with temperature and conductivity readings.
Remove the probe from the water. The unit will emit 4.
the same audio and visual indication and a blinking
cursor will appear on the display panel.
Field Use
Press the red power button. A blinking cursor 1.
appears in the display panel.
Slowly lower the probe until a brief light and buzz 2.
indicate the presence of water.
Take note of the marking on the tape. This is the 3.
static water level.
After 3 seconds the display updates with the 4.
temperature and conductivity values. Allow 10
seconds for the readings to stabilize.
Continue to lower the probe and take readings of 5.
temperature and conductivity at the desired depths.
When the probe is removed from the water, the 6.
unit emits a brief buzz while the LED lights, and the
display panel clears.
Note: The probe detects more accurately going into water than
coming out of the water. There is a slight switching delay
when the probe is moved from water to air.
Calibration
For best results, calibrate the Rugged Conductivity
Meter in 1,413 µS/cm solution at 25° C before starting a
measurement session.
Clean the probe with distilled water and allow it to dry.1.
Press the power button to turn the meter on.2.
Place the probe in 1,413 µS/cm solution and gently 3.
position the probe so that air bubbles are not trapped
under the shroud.
Wait approximately 10 seconds for readings to stabilize.4.
Press and hold the calibration button on the control 5.
panel until “Please Wait” appears on the display, then
release the button.
The meter will calibrate, after which the conductivity 6.
and temperature values will appear on the display
panel. The calibration values are stored until the meter
is recalibrated.
Troubleshooting
General
Tighten the knobs that secure the control panel to the
wheel, Figure 1, numbers 2 and 5.
The unit turns o when the probe contacts water
Replace the battery (Figure 1, number 1).1.
Check the tape for cuts that would allow water to 2.
enter. This condition may require factory service.
The unit does not calibrate properly
Gently move the probe to displace air bubbles and 1.
perform calibration.
Ensure that temperature readings are stable before 2.
performing calibration.
Clean the probe tip in distilled water, dry the probe, 3.
and perform calibration.
