5.1.2 

Manual Temperature Compensation (pH) 

IMPORTANT:  For manual compensation, you must 

disconnect the temperature probe (see section 3.2: Probe 

Information).  

1.

Switch the meter on.  Press the 

MODE

 key to select

pH mode.

2.

Press 

the 

CAL/MEAS

 key to enter pH calibration

mode. The CAL indicator will appear above the

primary display.

3.

While in pH calibration mode, press the 

MODE

 key to

enter temperature calibration mode.  The primary

display shows the current temperature setting and the

secondary display shows the default value 25 

°

C.

4.

Check the temperature of your sample using an

accurate thermometer.

5.

Press 

the 

 

or

 

 keys to set the temperature to the

measured value from step 4.

6.

Press 

ENTER

 to confirm the selected temperature

and to return to the pH measurement mode.

See Figure 13.  

The meter will now compensate pH readings for the 

manually set temperature.  

NOTES: 

To exit this program without confirming the manual temperature compensation value, DO NOT 

press 

ENTER

 in step 6.  Press 

CAL/MEAS

 instead.
