Product Description General Information:EP8420 Dual-clamp digital phase meter is a multi-functional instrument developed specially for on-site test. Featured with high precision, good stability, less power consumption and easy operation, it measures directly A.C. voltage and A.C. current even when the tested circuit is not opened, as well as phase between two voltages, two currents and the voltage-current. In addition, it measures indirectly power factor and power of the circuit, identifies three-phase sequence, wiring group, inductive and capacitive circuit of transformer, tests secondary circuit and the busbar differential protection system, tells the phase relation between different CT groups of differential protection, examines whether the wiring of watt-hour meter is correct, and checks and repairs circuit equipment, etc. The instrument has huge LCD screen, with letters reaching 40mm in height and looks greatly clear thanks to the backlight design. The instrument is applicable to electricity, petrochemical engineering, metallurgy, railway, meteorology, industrial and mining enterprises, academic institutions, colleges and metrological sectors, etc.Technical SpecificationsReference Conditions and Operating ConditionsInfluence FactorsReference ConditionsOperating ConditionsRemarksAmbient environment23oC±1oC-10oC~40oC Ambient humidity40%~60%<80% Signal waveformSine waveSine waveβ=0.05Signal frequency50HZ±1HZ45HZ~65HZ Working voltage9V±0.1V9V±1V Phase current range applicable1A±0.1A10mA~20.0A Phase voltage range applicable100V±10V30V~600V External electric field and magnetic fieldShall be avoidedLocation of tested wireThe tested wire is located in approximate geometric center of the clamp jawGeneral Specifications FunctionDirectly test phase, A.C. current, A.C. voltage, A.C. leak current, and phase sequence; identify grouping, inductive, and capacitive circuit of transformer; and indirectly test power factor and power.Power SupplyDC9V alkaline dry batteries (1.5V AA×6)Power ConsumptionNearly 35mA at the maximum if backlight on, batteries work continuously for nearly 40 hours.Nearly 5mA if backlight off, batteries work continuously for 300 hours. DisplayLCD display, blue screen with backlight design, applicable to dark places.
