2/3-wire earth tester

The ET-23 is a portable digital earth resistance tester for field verification of grounding systems in power distribution, lightning protection, telecommunications and photovoltaic installations. It measures earth resistance by 2-wire and 3-wire methods, earth voltage, PV string voltage up to 1500V DC and AC voltage up to 750V. Auto-ranging, data hold and a backlit LCD make it practical for outdoor and switchroom work.

FAQ
What measurement methods does the ET-23 support?
The ET-23 supports 2-wire and 3-wire earth resistance measurements across 0.03 Ω – 4000 Ω.
Why should I zero the test leads before measuring?
Test leads have residual resistance. Zeroing or storing the Rk value lets the meter subtract this resistance, improving accuracy on low-ohm ranges.
Can it measure PV system voltage?
Yes. The ET-23 measures PV voltage up to 1500V DC and AC voltage up to 750V.
What batteries does it use?
The ET-23 is powered by 6 × 1.5V AA alkaline batteries, which are included.
What is the auto power-off time?
The meter switches off automatically after 30 minutes of no operation in earth resistance mode.
Which industries is it used in?
Typical applications include transformer grounding, lightning protection, transmission towers, railway tracks, oil tanks and telecom base stations.
