PCE-PCM 1 is a multipurpose current clamp or power analyzer used to measure alternating current (AC), voltage (TRMS) and frequency to determine active (kW), apparent (kVA) and reactive (kVAR) power as well as active energy (kWh) consumption. Both the phase angle and the power factor (cos φ) are shown on the handheld power meter's large and easy-to-read backlit display.
The current clamp has a measuring range of 0 … 1000 A AC/DC. The current is measured inductively using the clamp on the measuring device. Live supply lines with a diameter of up to 32 mm (1.2") can be connected to the current clamp.
With the Current Clamp it is possible to measure leakage currents up to a range of 100 A. The Current Clamp can measure leakage currents which appear when current flows through electrical conductors which are not designed for conduction current.
