Digital Earth Resistance Tester (3 Terminal)

Model - KM 1520A

“KUSAM-MECO” Digital Earth Resistance Tester is a very versatile & handy instrument for checking Earth Resistance. It consists of the indicator & set of 3 spikes (stake) and connecting wires. Earth Resistance is measured by putting the spikes in the earth at distance of 5-10m (as shown below) & switching ON the instrument indicates the Earth Resistance directly in ohms.

Features :
Earth Resistance Measuring range : 0-40 Ω / 400 Ω / 4000 Ω
Measure Earth Voltage (VAC) : 0-400V
Low 2mA measuring current permits earth
  resistance to test without tripping earth leakage
 current circuit breakers in the circuit.

Capable of measuring earth voltage(Vac).
Auto power off function. The timer operates
  automatically about three to five minutes after
  the”PUSH BUTTON SWITCH” and “Timer ON
  BUTTON” are pressed together This will keep the
  test “ON” for about three to five Minutes.
  Then auto power off.

Battery operated.
Operating Temperature & Humidity : 0 ~ 40°C; 80% RH Max.



Data Hold function.
Small and light weight
EN61010-1 CAT IV 400V.
Display Back-light
External probe
CE-Mark approval
