Without Temperature Probe (no ATC)
If no temperature probe is used, the meter compensates for pH response based on a 
temperature value manually set by you or at 25.0 
o
C (factory default).
1. Press
MODE key to enter into Temperature mode until “
o
C” shows in LCD.
 
2. Compare the displayed value to NIST certified thermometer or thermometer known 
to be accurate (dipped into a constant temperature bath).
3. Press CAL key to enter temperature calibration mode. The LCD shows “CA”
momentarily and displayed reading flashes. Note that this displayed value should 
either be 25.0 
o
C or last set temperature value.
 
4. Press 
S and T key (for Ion 6) or INC key (for pH 5/6) until the displays shows the
desired temperature. You can set any value from 0 to 100
o
C.
5. To cancel or abort this operation, press CAL key. Note no new value will be stored
into its meter‘s non-volatile memory. To confirm calibration, press ENTER key. The 
LCD displays “CO” momentarily, and the meter reverts to measurement mode.
