RS PRO IET1700 Earth Tester, 3999Ω RS Calibration

The RS PRO IET1700 is a great value 3-pole digital earth tester. Earth resistance testers are electrical devices that are used to ensure the grounding resistance of appliances and equipment is sufficient. The 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.

These small instruments are vital for ensuring a safe path to earth is established in case of utility over voltage or lightning strike. This test and measurement instrument is used in various applications for testing earthing installation in power-based industries, telecommunication networks and electrical traction systems.

Earth & ground resistance testers are types of devices ideal for testing and measuring electrical systems to ensure they are grounded and the current has a safe path to earth, in case of utility over voltage or lightning strike. These instruments are often used by:

• Electrical contractors


• Inspectors


• Telephone technicians

Does this device come with batteries?
Yes, the IET 1700 comes with 8 x AA batteries

Why is grounding important?
Grounding is an essential element for any electrical installation as it protects appliances and stabilises voltage levels. Grounding also prevents the risk of injury or death from a sudden over voltage or fault.

Earthing is also important is it also provides a safe path for electrical currents to travel to earth in the event of over voltage or lightning strike, ultimately preventing injury through electric shock or death.
