display.
[b] Ensure that the ambient temperature is stable within ±1 ºC. Ensure that the clamp meter is placed in a controlled environment for at least
1 hour before you proceed to ensure that the clamp meter's internal reference junction sensor and input terminal are stabilized at the same
environment. Keep the clamp meter away from any ventilation exit.
Differences in ambient compensation between the calibrator and clamp meter may cause some deviations shown between the readings of
the calibrator and clamp meter. Placing the clamp meter close to the output terminal of the calibrator will help reduce this deviation.
Keep the thermocouple test lead as close to the clamp meter as possible.
Do not touch the thermocouple test lead after connecting it to the calibrator. Allow the connection to stabilize for at least another
15 minutes before performing the measurement.
