The Conductivity electrode (EC-CONSEN91W/ 35608-50) has a built-in temperature
sensor for ATC. The temperature sensor is factory calibrated to the meter. Calibrate
your sensor only if you suspect temperature errors that may have occurred over a long
period of time or if you have a replacement probe.
Temperature Calibration
1. Make sure the electrode is attached to the 6-pin connector.
2. Power the meter on. The [ATC] indicator will appear at the right-hand side of the
LCD to indicate that the temperature sensor is in good working condition. If the ATC
indicator does not light up, see SETUP sub-menu P3.3 to switch it on.
3. Press MODE key to select either conductivity or TDS mode.
4. Press CAL/MEAS to enter either Conductivity or TDS calibration mode. The [CAL]
indicator appears above the upper display.
5. While you are in the Conductivity or TDS calibration mode, press MODE to enter
into Temperature calibration mode. The upper display shows current temperature
reading and the lower display shows the factory default temperature value.
6. Dip the electrode into a solution of known temperature (i.e. a constant temperature
bath). Allow about 3 to 5 minutes for the built-in temperature sensor to stabilize its
measured reading.
7. Adjust using the MI/▲ or MR/▼ key to set to the correct temperature value (i.e. the
temperature of the constant temperature bath) in increments of 0.1 °C. Maximum
allowable offset temperature value is 5.0 °C.
8. Once you have selected the correct temperature, press ENTER key. To abort or exit
this calibration mode without confirming the temperature calibration value, DO NOT
press ENTER key. Press CAL/MEAS key instead and the meter automatically
reverts back to the measurement mode.
