Digital Earth Resistance Tester (3 Terminal)

Special Features:
<br>
• <b>Earth Resistance Measuring range :</b> 0-40 Ω / 400 Ω / 4000 Ω<br>
• <b>Measure Earth Voltage (VAC) :</b> 0-400V<br>
• <b>Low 2mA measuring current permits earth<br>
  resistance to test without tripping earth leakage <br> current circuit breakers in the circuit.</b><br>
• <b>Capable of measuring earth voltage(Vac).</b><br>
• <b>Auto power off function. The timer operates <br>  automatically about three
to five minutes after <br>  the”PUSH BUTTON SWITCH” and “Timer ON <br> 
BUTTON”
are pressed together This will keep the <br>
  test “ON” for about three to five
Minutes. <br>
  Then auto power off.</b><br>
