1. Or short test leads and use REL to offset test lead resistance.
2. Remove test leads from unit.
3. To ensure accurate measurement, the Meter and thermocouple adapter must be at the same temperature. After connecting the thermocouple
adapter to the Meter allow for reading to stabalize before recording display reading.
4. The Meter accuracy is not specified at this input signal frequency with Low-pass filter selected. The display reading shown, check that the Low-pass
filter is active and follows an expected roll-off curve.
5. Use REL to compensate for internal Meter and lead capacitance. The test leads must be disconnected from the calibrator before pushing REL.
