3.4 Temperature Calibration

With Temperature Probe (Automatic T

emperature Compensation)

The thermistor sensor used for temperature measurement is accurate and stable, so

frequent calibration isn’t required. Temperature calibration is recommended upon

electrode replacement, whenever the temperature reading is suspect, or if matching

against a certified thermometer is desired.

If temper

ature calibration will be performed, be sure that the thermometry

source being used as a reference is accurate!

Turn on the meter and select °C mode by pressing

if necessary. Connect the

temperature probe and place it into a solution with a known accurate temperature

such as a constant temperature bath or NIST-traceable thermometer. Allow

adequate time to stabilize.

2. Press

to begin temperature calibration mode. “” (calibrate) will display

briefly. The un-adjusted °C value will blink.

3. Compare the measured value of the 5+/6+ temperature probe with the reference

thermometer. Use

(pH 5+ and pH 6+) or (Ion 6+) to adjust the

reading to the desired value. The maximum adjustment is ± 5 °C.

4. Press

to confirm the value. “” (confirm) will display briefly. The meter will

automatically save the calibration, cease blinking, and begin °C measurement.
