4.3 Temperature
Calibration
Your electrode features a built-in temperature sensor. The temperature sensor is
factory calibrated. Calibrate your sensor only if you suspect temperature errors may
have occurred over a long period of time or if you have a
replacement electrode.
1. Make sure the electrode is attached to the 6-pin
connector. The ATC annunciator will appear at the
bottom right-hand corner of the LCD.
2. Switch the meter on. Press the CAL/MEAS key to
enter conductivity or TDS calibration mode. The CAL
indicator appears above the primary display.
3. While in conductivity or TDS calibration mode, press
the MODE key to enter temperature calibration
mode. The primary display shows the current
measured temperature reading based on the last set
offset and the secondary display shows the current
measured temperature reading based on factory
default calibration.
4. Dip the electrode into a solution of known
temperature (i.e. a temperature bath). Allow time for
the built-in temperature sensor to stabilise.
5.
Scroll with the MI/

or MR/
▼
keys to set the correct
temperature value (i.e. the temperature of the
temperature bath). You can adjust the reading in
increments of 0.1
°C.
6. Once you have selected the correct temperature,
press the HOLD/ENTER key to confirm. The meter
will be calibrated and return to the measurement
mode.
NOTES:
•
To exit this program without confirming the
temperature calibration value, DO NOT press
HOLD/ENTER. Press CAL/MEAS instead.
•
If the ATC indicator does not light up, see SETUP
menu Program P1.3 to switch it on. See page 40.
•
Since temperature readings affect the accuracy of
conductivity / TDS measurements, it is strongly
recommended to carry out a conductivity / TDS
calibration after a temperature calibration is done.
