4.3 Temperature

Calibration

Your probe features a built-in temperature sensor. The
temperature sensor is factory calibrated. 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 cell is attached to the 6-pin connector.
The ATC annunciator will appear at the right-hand
side of the LCD*.

2.

Switch the meter on. Press the MODE key to select
conductivity or TDS mode.

3. Press

the

CAL/MEAS key to enter conductivity or

TDS calibration mode. The CAL indicator appears
above the primary display.

4.

While in conductivity or TDS calibration mode, press
the MODE key to enter temperature calibration
mode. The primary display shows the current
temperature reading and the secondary display
shows the factory default temperature value.

5.

Dip the cell into a solution of known temperature (i.e.
A temperature bath). Allow time for the built-in
temperature sensor to stabilise.

6.

Scroll with the MI/S or MR/T 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.

7.

Once you have selected the correct temperature,
press the ENTER key.

* If the ATC indicator does not light up, see Program P4.3
to switch it on.

NOTES:

You can offset the temperature reading up to

±5°C from

the original reading (default reading).

To exit this program without confirming the temperature
calibration value, DO NOT press ENTER. Press
CAL/MEAS instead.

If the ATC indicator does not light, see Program P4.3,
on page 32 to switch it on.

Since temperature readings affect the accuracy of the
conductivity/TDS measurements, it is strongly
recommended to carry out a conductivity/TDS
calibration after a temperature calibration is done.
