Temperature settings

Calibrating temperature sensor

The temperature sensor or temperature compensation electrode in the combination
electrode has ±1°C accuracy without calibration. You can use a known temperature
solution to calibrate the temperature sensor.

1.  Insert the temperature connector into the temperature connector (T) on the

instrument.

2.  Immerse the electrode into the solution until the temperature sensor is

immersed.

3.  Press the 

 key to enter the setting mode.

4.  Press the 

 keys to select "TEMP" (temperature calibration setting) and

then press the 

 key.

5.  Make sure that "ATC" is displayed, and press the 

 key.

The temperature setting screen is displayed.

6.  Enter the set temperature and press the 

 key to confirm.

The temperature sensor is calibrated.
