3.4 Temperature Calibration
3.4.1 With Temperature Probe
The temperature probe (ECPH5TEM01P) provided with the meter is factory-calibrated.
Over time, temperature calibration may drift and require calibration. If there is a need to
replace with the new probe you should calibrate the temperature probe prior to pH
calibration.
1. Connect your temperature probe to the meter. Press MODE key to enter the
Temperature mode until “ o C” annunciator appears in the LCD.
2. Compare the displayed value to a NIST certified thermometer or other thermometer
known to be accurate. For best accuracy, place both the probe and thermometer in
a constant temperature bath.
3. Press CAL key to enter temperature calibration mode. The LCD shows “CA”
momentarily and displayed reading flashes.
4. Press S and T keys (for Ion 6+) or INC key (for pH 5+ / pH 6+) until the LCD
display shows the desired temperature. The meter allows an adjustable maximum
value of ± 5
o C from factory default.
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.
