First, the product overview

PY2000B double-clamp digital phase voltammeter is a high-precision, low-cost, hand-held, dual-channel input measuring instrument designed for field measurement of voltage, current and phase. The table can be easily measured in the field UU , II and UI between the phase, to determine the inductive, capacitive circuit and three-phase voltage phase sequence, the detection of the transformer wiring group, test the secondary circuit and bus differential protection system, read the differential protection between the groups CT Of the phase relationship, check the watt meter wiring is correct or not, etc. The use of clamp current transformer conversion method input current measured, so the measurement without disconnecting the measured line. U1-U2 measured between the phase, the two input circuit Completely insulated and isolated, so completely avoid the possibility of mistaken wiring caused by the measured circuit short circuit, so burned measuring instruments. Display using a high contrast LCD screen, the word up to 25mm, the screen angle can be freely converted about 70 ° to get the most Good visual effect.
Double-clamp digital phase voltammeter shell with engineering insulation material, reprovision rubber protective cover, safe and reliable.
