3. CALIBRATION
3.1 Temperature Calibration
The temperature sensor included (only for Temp 5) with your meter is factory
calibrated. Over time, the temperature calibration may drift and the probe
requires recalibration. The Temp 4/5/6 meters allow you to have a 1-point
calibration as fine adjustment by changing its offset value. This is useful if you
replace the probe and should recalibrate the probe to the meter.
3.1.1 Temperature Calibration using Offset Adjustment
1. First connect the temperature probe to the meter. Press ON/OFF key to
power up the meter and wait for meter to enter measurement mode.
2. Dip the probe in a constant temperature bath, or in liquid whose
temperature can be checked with an accurate thermometer. For best
accuracy, place the probe and thermometer in a constant temperature bath.
3. Wait for readings to stabilise.
4. To enter temperature calibration mode, press and hold CAL key for 5
seconds before release. The LCD shows “ CA ” momentarily and a value
flashes.
5. Press MAX/ ▲ or MIN/ ▼ key to adjust the displayed value until it matches
the correct temperature. The MAX/ ▲ or MIN/ ▼ key will scroll to the
maximum allowable value.
NOTE: The maximum adjustments allowed are ±5 °C from factory default.
