Technical Data

The Fluke 1621 is an easy-to-use earth ground tester.

The first line of defense in detecting reliable ground

connections, the unit features basic ground testing

methods including 3-pole Fall-of-Potential as well as

2-pole ground resistance. Its convenient size, rugged

holster, and large, clear LCD display make it an ideal

field earth tester, for most work environments. With

a simple user interface and intuitive functionality, the

Fluke 1621 is a handy tool for electrical contractors,

utility test engineers, and earth ground specialists.

Between jacks S/P2 and E/C1: 250 Veff maximum

Climatic class VDE/VDI 3540 RZ (conforming to KWG as per DIN 40040, 4/87)

Temperature performance Working: -10 °C to +50 °C (+14 °F to +122 °F)

Operating: 0 °C to +35 °C (+32 °F to +95 °F)

Storage: -20 °C to +60 °C (+68 °F to +140 °F)

Reference: +23 °C ± 2 °C (+73 °F ± 4 °F)

Note: If the tester is not going to be used, or is being stored for a long period, remove the battery and store separately from the tester to avoid

damage from battery leakage.

Note: The four temperature ranges for the tester exists to satisfy European Standards requirements; the instrument can be used over the full

working temperature range by using the temperature coefficient to calculate accuracy at the ambient temperature of use.
