2 Press CAL to begin mV calibration mode. "CA" (calibrate) will display briefly.
The un-adjusted mV value will blink.
3 Use MODE/INC to adjust the reading to the desired value. The maximum
adjustment is ± 50 mV.
4 When the reading has stabilised, the mV annunciator will stop blinking.
Press HOLD/ENTER to confirm the value. "CO" (confirm) will display
briefly. The meter will automatically save the calibration, cease blinking,
and begin mV measurement.
3.3 Temperature Calibration
With Temperature Probe (Automatic Temperature 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.
Note: If temperature calibration will be performed, be sure that
the thermometry source being used as a reference is accurate!
1 Turn on the meter and select °C mode by pressing MODE 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 stabilise.
