3.1.2 Temperature Curve Selection (Temp 5 Meter Only)
In the event temperature probe has drifted too far from its original characteristic
– due to age and use or if the probe is being replaced, it may be a good idea to
match probe to the best curve. There are 3 curves programmed in the unit. To
choose the curve, proceed as follows:
1. Connect your temperature probe to the meter. Dip the probe in a constant
temperature bath or a liquid whose temperature can be checked with a
thermometer known to be accurate. For best accuracy, place the probe
and thermometer in a constant temperature bath.
2. Turn on the meter. Make sure that the meter is in the measurement mode.
Press CAL key for 5 seconds to enter calibration mode. The LCD shows
“CA” and the reading flashes.
3. Press o C/ o F key to enter curve selection mode. Press the o C/ o F key again
to scroll through three temperature curves (low, mid. high). Each press will
take you through one curve. Choose the curve which gives you a reading
closest to the actual value (of the bath or thermometer).
4. Press ENTER key and the curve selection is complete. The unit will display
“CO” and revert to the temperature calibration mode, with the display still
flashing.
5. Press S and T key to make fine adjustment until the display shows the
correct desired temperature. The S and T key will scroll to the maximum
allowable value (maximum adjustment is ±5
o C from factory default).
6. Press ENTER key to confirm calibration. The LCD displays “CO”
momentarily, and the meter then reverts to measurement mode.
