ITEM NAME:2X(Double Display Digital Ac Voltmeter Digital Display Current Meter Dl69-2V6U2) 2X(Double Display Digital Ac Voltmeter Digital Display Current Meter Dl69-2V6U2) 2X(measurement accuracy: 1%, plus or minus 2 words. Display: Voltage display: 4 bit red 0.39 inch LED digital tube, current display: 4 bit green 0.39 inch LED digital tube Measurement range: AC voltage: AC80-300V (single-phase) 200-450V (three-phase) AC current: AC0-100.0A, measurement current less than 10A when the current display resolution is 0.01A, measurement current greater than 10A when the display resolution is 0.1A, range automatic conversion (decimal point automatic shift) true RMS measurement power consumption: 0.2VA measuring speed: about 2 times per second. AC80-300V 100A aperture 15.5mm suitable for AC 110V 220V press size: 76*39mm (embedded installation) explain: the mutual inductor is separated from the instrument, and the transformer can be installed according to the actual position of the measurement. That is to say, the lead can be lengthened to the Perfect location of the equipment. Note: voltage input - Green terminal If the current transformer is input to the blue terminal for the two time, it will not get the wrong connection, otherwise it will burn the meter. Application and wiring method Connect the secondary terminal (green lead) of the current transformer with the instrument to the blue terminal of the instrument according to the wiring diagram of the attached drawing, and pass the measuring circuit lead through the middle circular hole of the current transformer. matters needing attention 1) Voltage input (green terminal) and current transformer secondary input (blue terminal) can not be wrong, otherwise the instrument will be burned out 2) This instrument is only suitable for the pure AC 50-60HZ power supply. It can not be used in the square wave, inverter output and sine wave circuit to correct the sine wave. Otherwise, the instrument will be permanently damaged. Col)
