Test Considerations
⚫ Ensure that the test ambient temperature is stable and between 18°C and
28°C. Ideally the calibration should be performed at 23°C±2°C.
⚫ Ensure ambient relative humidity is less than 80%.
⚫ Allow a 30 minute warm–up period with a copper short connected.
⚫ Ensure the measuring rate is set to “slow” for DCV, ACV, DCI, ACI and
2-Wire/ 4-Wire Resistance measurements.
