SEW 1820 ER 3 Wire Digital Earth Resistance Tester

AT-8 High Accuracy Digital Tachometer

OVERVIEW:

The SEW 1820 ER meter is used to measure the ground resistance to 2000 Ω using a two-wire circuit (RUGBT mode) and a three-wire circuit (EXACTLY mode), as well as a step voltage up to 200 V.

Features:

Capable of measuring earth resistance and earth voltage.

2 mA measuring current permits the testing of earth

resistance without tripping earth leakage current

breakers in the circuit under test.

The test leads are supplied as standard accessories for

simplified two-wire measuring system.

Battery operated.

Data hold function.

Low battery indication.

Calibration performed with supplied test leads.
