4.7 Temperature Calibration
The conductivity electrode (EC-CONSEN91W/ 35608-50)
supplied with the meter has a built-in temperature sensor. In
addition you can also use a separate temperature sensing
element supplied by Eutech Instruments (as such
temperature probe (EC-PHWPTEMP-01W/ 35618-05), or the
“3-in-1” pH/Temperature combination electrode, (EC-
FE73528-01W/ 35808-71) for ATC purpose.
The conductivity probe is factory calibrated. Temperature
calibration can be done 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 is accessible during pH or
conductivity or TDS calibration.
Temperature Calibration
1. Make sure the conductivity electrode (or temperature
probe or “3-in-1” electrode) is attached to the 6-pin
connector.
2. Switch the meter on.
3. Press the CAL/MEAS key to enter calibration mode
(either from pH or conductivity mode). The CAL
indicator will appear above the primary display.
4. While in pH (or conductivity or TDS) calibration mode,
press the MODE key to enter temperature calibration
mode. The primary display shows the last set
temperature value and the secondary display shows the
temperature reading with zero offset.
5. Dip the ATC probe into a solution of known temperature
(i.e. a temperature bath). Allow time for the temperature
probe to stabilize.
