Description

In order to reduce Broadband and ISDN Line transmission losses, it is essential to check Earth resistance. With this tester we can check earth resistance up to 0.1 ohms. We can also measure soil resistivity. Unit works on chargeable battery. Necessary accessories along with charger are provided with unit.

Features

  • Measurement up to 0.1 Ohms
  • Accuracy up to 2%
  • Digital display
  • Generated signal is not in range of harmonics of mains supply to avoid interference
  • Test resistor are provided to confirm calibration
  • Low battery consumption
  • Battery is chargeable maintenance free type
  • Heavy duty accessories provided for proper reading

Operation

Short left side two terminals E1 & P1 and connect it to point whose resistance is to be measured. This wire should be shortest possible. Connect other 2 wire provided along with unit to other two terminals. Fix the rods at app.10 to 15 meters in different directions. Pour a glass of water on the rod to make good contact. Select 2V range & press test button. Then display will give direct reading of earth resistance.
