GF211 Double Clamp Digital Phase Meter

Application

Applicable to relay protection, electric powermeasure, electric power construction and conversion engineering andother professional, is the electric power department, factories andmines, the petroleum chemical industry, the metallurgy system forthe secondary circuit check ideal electric meters.

Introduction

GF211 double clamp digital phase table is designedfor the measuring voltage, current and phase and design of a lowprice, portable handheld, double channel input measuringinstrument. Use the table can be easily in the field measurementU-U, I-I, U-I between the phase, discriminant sensibility,capacitive circuit and the voltage of the three-phase sequence, todetect transformer of wiring categories, test the secondary circuitand mother differential protection system, read the differentialprotection group the phase relationship between CT, check thewiring of meter is correct or not. The clamp ampere currenttransformer switch pattern input is measure current, so whenmeasuring the disconnect was without measurement circuits.Measurement of the phase of the U1-U2 between two input circuitcompletely insulation isolation, so to avoid completely possibleerror caused by wiring measured short circuit, so that burnedmeasuring instrument. The display USES a high contrast LCD screen,word up to 25 mm, screen Angle can be free the conversion of 700,in order to get the best visual effect. The data in this table isowed the function of electricity can timely remind the operator toreplace batteries to be automatic shutdown function can be shut offwithin 15 minutes in power, to extend battery life. Repeat thepower switch operation, can be bootable again measurements.

Instrument shell using a multimeter structure,engineering insulation materials, the other with rubber covervibration control, safe and reliable.

GF211 with high precision small clamps head toimprove current precision measuring clamp, facilitate field wiringa dense environment is used.
