The Three-Terminal Ground Resistance Tester is the economical choice for electrical contractors, plant electricians, telephone and CATV technicians making routine ground resistance tests on single electrodes and other simple grounding systems. The instrument is easy to use for quick measurement of resistances from 0.5 to 500 ohms.

Because factors such as seasonal variations in temperature, moisture and salt content affect soil resistivity, periodic tests are essential to ensure that resistance to ground remains at a safe value.

The instrument is simple to operate:
Drive probes and hook up the leads.
Push switch to READ and ground resistance is displayed directly.
If reading is questionable, switch to CHECK to verify test lead continuity and probe resistance.

Designed for simplicity of use, the instrument is operated by a single three-position switch to read the measurement, check the probe resistance and turn the instrument off. Measurements are displayed directly in ohms; range changing, multipliers or calibration adjustments are not necessary.

Features:
Measures ground resistance down to 0.5 ohm
Reads directly in ohms on a single range scale
Stable calibration — requires no field adjustments
Checks probe resistance and battery condition
Powered by replaceable C cells
Limits output to 50 volts open circuit, 5 mA short circuit
Weighs less than 3 lb ( 1.5 kg)

Applications:
Utility poles
Distribution transformers
Residential wiring systems
Lightning arresters
Computer grounds
Machinery safety grounds
Telecommunication and data transmission systems
Railway electric substations and signal systems
Antistatic grounds
