THERMOCOUPLE Range Calibration
1. Use the arrow keys to display and press PAR. Then choose and
press PAR.
2. At , apply a dead short or set calibrator to zero to input terminals 4 and
5. Wait 10 seconds, then press PAR.
3. At , apply 50.000 mV input signal (with an accuracy of 0.01% or
better) to input terminals 4 and 5. Wait 10 seconds, then press PAR.
4. Return to the Display Mode.
5. Continue with Ice Point Calibration.
ICE POINT Calibration
1. The ambient temperature must be within 20 °C to 30°C.
2. Connect a thermocouple (types T, E, J, K, or N only) with an accuracy of 1 °C
or better to the meter.
3. Verify the readout Display Offset is 0, Temperature Scale is °C, Display
Resolution is 0.0, and the Input Range is set for the connected thermocouple.
4. Place the thermocouple in close thermal contact to a reference thermometer
probe. (Use a reference thermometer with an accuracy of 0.25 °C or better.)
The two probes should be shielded from air movement and allowed sufficient
time to equalize in temperature. (A calibration bath could be used in place of
the thermometer.)
5. In the Normal Display mode, compare the readouts.
6. If a difference exists then continue with the calibration.
7. Enter Module 9, use the arrow keys to display
and press PAR. Then
choose and press PAR.
8. Calculate a new Ice Point value using: existing Ice Point value + (reference
temperature - Display Mode reading). All values are based on °C.
9. Enter the new Ice Point value.
10. Return to the Display Mode and verify the input reading (with 0 Display
Offset) is correct. If not correct repeat steps 8 through 10.
