3 Terminal Digital Earth Resistance Tester
Model KM 1520
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.
• Earth Resistance Measuring range : 0-20Ω / 200Ω / 2000Ω
• Measure Earth Voltage (VAC) : 0-200VAC
• 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..
