5. Calibration
Temperature calibration using offset adjustment
The temperature sensor included with your meter is factory calibrated. Over time,
the temperature calibration may drift and require recalibration. If you replace the
probe you should recalibrate.
1. Connect your temperature probe to the meter. Turn meter on. Meter enters
measurement mode.
2. Compare displayed value to a NIST certified thermometer or other thermometer
known to be accurate. For best accuracy, place probe and thermometer in a con-
stant temperature bath.
3. Press the CAL key to enter calibration mode.
The LCD shows "CA" and the reading flashes.
See figures
4. Use the ▲ and ▼ keys to adjust the
temperature shown to match the accurate
temperature (maximum adjustment is
±10°C / ±18°F from factory default).
5. Press ENTER key to confirm calibration.
The LCD displays "CO", and the meter
then reverts to measurement mode.
