1621 Earth Ground Tester
Introduction
The Fluke 1621 Earth Ground Tester (referred throughout as the “Tester”) is
an easy to use instrument for measuring the resistance to earth ground of a
specified earth ground electrode. The Tester can perform a 3-pole fall-of-
potential test conforming to IEC/EN 61557-5. The Tester can also perform ac
resistance testing.
To further simplify and increase the probability of an accurate measurement in
the 3-pole mode, the Tester measures the resistance of the probe and auxiliary
electrode to verify that they are within prescribed limits. The Tester also tests
for stray interference voltage (noise) and indicates if the value is too high to
take a proper measurement.
The Tester features a lighted LCD display, automatic shut-off, and a limits
mode for setting maximum resistance readings.
This instrument is manufactured in compliance with quality assurance system
EN ISO 9001. Compliance with current applicable EMC regulations is
documented by the attached P sign.
