The Ideal 61-796 earth ground tester performs 2-point and 3-point fall-of-potential or simplified ground resistance testing when it is not possible to use auxiliary ground stakes, and measures ground voltage for new and existing buildings, structures, equipment, and electrical systems. The auto-ranging feature automatically determines the correct value range for the measurements. The data hold function with screen icon allows the user to retain the measurements on the display for manual recording. The battery indicator alerts the user when batteries are low to ensure accurate measurements. When in use, the 2 milliAmp (mA) measuring current does not trip ground fault breakers of the circuit under test. Ground-resistance meters are used by electricians and contractors working in industrial, utility, and field servicing.
The Ideal 61-796 tester comes with a set of three test leads, two auxiliary earth spikes, a simplified measurement probe, a hard carrying case, and an instruction manual. Applicable safety standards are IEC/EN 61010-1 and Installation CAT III 200V. The meter is rated for use at pollution degree 2.

Ground-resistance meters test the condition of a grounding system, and provide resistivity measurements in ohms. The meters are available in digital, analog, and clamp models. Grounding systems protect people and equipment, and provide a safe path for the dissipation of fault currents, lightning strikes, static discharges, EMI and RFI signals, and interference. Regular testing of a grounding system is important for safety and protection of equipment. For example, corrosive soil with high moisture content can degrade ground rods and connections in existing systems and increase the resistance of the system. Ground-resistance meters are used in conjunction with a variety of testing methods to troubleshoot intermittent electrical problems or as part of a regular maintenance plan.
