Electrode Replacement
You can replace the electrode module at the fraction of the cost of a new tester. When the tester fails
to calibrate or gives fluctuating readings in calibration standards, you need to change the electrode.
1. With dry hands, grip the ribbed tester collar with electrode facing you. Twist the collar counter
clockwise (see picture A). Save the ribbed tester collar and O-ring for later use.
2. Pull the old electrode module away from the tester.
3. Align the four tabs on the new module so that they match the four slots on the tester (see
picture B).
4. Gently push the module onto the slots to sit it in position. Push the smaller O-ring fully onto
the new electrode module. Push the collar over the module and thread it into place by firmly
twisting clockwise.
Note: It is necessary that you recalibrate your tester prior to measurement after an electrode
replacement.

Temperature Calibration (Only for PLUS Models)
Temperature calibration need not be performed every time, unless the temperature reading differs
from that of an accurate thermometer. If temperature calibration is performed, Conductivity/TDS/Salt
calibration is mandatory.
From the measurement mode,
1. Press the °C/°F button to select the desired temperature mode (Celsius or Fahrenheit).
2. Dip the tester into a solution of known temperature and allow time for the in built temperature
sensor to stabilize.
3. Press either the INC or DEC key to bring the tester to the calibration mode.
Note: At this stage, if the Conductivity/TDS/Salt reading is outside the specified range (showing Or
or Ur), the tester will show an error message of “Er.1”. You can still proceed with the temperature
calibration by continuing with step 4 or if the °C/°F button is not pressed within 2 seconds, the tester
will exit the calibration mode and return to the measurement mode.
4. Immediately press the °C/°F button to switch to the temperature calibration mode. The upper
display shows the current measured temperature reading based on the last set offset and the
lower display shows the current measured temperature reading based on factory default calibration.
5. Use the INC and DEC key to adjust the upper temperature reading to the known temperature value.
6. Wait for 5 seconds for the tester to automatically confirm the temperature calibration value by
displaying “CO” and return to the measurement mode.
Note: To exit this program without confirming the calibration, press the °C/°F button or the HOLD
button before the automatic confirmation takes place.
Note: The tester will exit calibration mode with “Er.0” message if the temperature is outside the 0 to
50°C range. Please refer to information under ’Self Diagnostic Messages’.
Notes: The temperature calibration window is +/- 5°C (+/- 9°F) from the default temperature reading.

Changing Batteries
1. Open the battery compartment lid (with attached lanyard loop).
2. Remove old batteries; replace with fresh ones. Note polarity
(shown in diagram below).
