Q & A

Q: What ground resistance methods can the Fluke 1621 perform?
A: The Fluke 1621 can be used for 3-pole Fall-of-Potential (IEC/EN 61557-5) and 2-pole ground resistance.

Q: The Fluke 1621 literature states it tests for stray interference. Why is this important?
A: The Fluke 1621 checks for interference voltage (noise) fault voltage above 20 V. Interference above 20 V greatly diminishes the accuracy of measurements
