Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop form, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit, and multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form on an LED screen.
The Megger 210415 15kV Analog Megohmeter is an analog meter that measures insulation resistance to help reduce shock hazards and downtime on electrical systems that include wires, cables, transformers, and electrical motors. A manual range-selection knob allows you to choose the measuring range and the continuously variable test voltage provides highly sensitive insulation resistance readings. The Megger 210415 tests insulation resistance with low- or high-voltage test voltages. The shielded high-voltage output cable is permanently attached to the unit to avoid damage to the unit. The Megger 210415 15kV Analog Megohmeter includes circuit breaker protection and redundant grounding connections for increased safety.
