3.1 Temperature Calibration
The temperature sensor included with your meter is factory calibrated. Over time,
the temperature calibration may drift and the probe requires re-calibration. The
Temp JKT meter allows you to have a 1-point calibration as fine adjustment by
changing its offset value. This is useful if you replace the probe. If you replace the
probe, you should recalibrate.
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 for the following meter series
from factory default are:
• EcoScan JKT Temperature meters = ±10 °C
•
EcoScan 4/5/6 Temperature meters = ±5 °C
