YB4835VA Digital Display AC 500V/50A LED Ampere Meter Voltmeter Current Solid Type

Specification:Measurement accuracy:1% 2 digitsDisplay: 0.39 inches LED digital tube display, voltage _ red, current _ greenMeasurement speed: about 2 times per secondDimensions:70 * 40 * 40 mmInstallation Dimensions:68 * 38 mmPower supply line, measuring line length: about 150mm"split" transformer lead length: about 100mm40/5000Operating temperature: -10 ~ + 50 Working humidity:10 ~ 80% (without condensation)Working pressure:80 ~ 106 kPaSunlight exposure: no direct exposureVoltage Range:AC 130~500VResolution:1VCurrent Range:AC 0~50AResolution:1A Features: Fixed: the transformer is fixed on the instrument. AC voltage, ammeter same screen, double color, double display, highlight large font. Simple connection of instrument:Two-wire system: no additional power supply, red and black wire connected to measure the voltage at the same time to the meter head power supply (no polarity). Current testing requires no additional purchase of transformer, instrument with a high transformer. In the watch head l set fine-tuning potentiometer, it can calibrate the voltage and current error by itself. The head of the split-type transformer has a back cover. It is safer, more convenient and more reliable to use.
