LED Digital Voltmeter Ammeter, Mini AC Digital Multimeter, LED Amp Dual Digital display Volt Meter Gauge Fixed Type/AC130-500V/AC0.0-50.0A

Feature:Split type: easy to install, the transformer is separated from the meter, the transformer can be installed according to the actual position of the measurement (the lead of the secondary end of the transformer can be lengthened to achieve the ideal installation position)Fixed type: The transformer is fixed on the meterSimple wiring of the instrument:Set the trimmer potentiometer in the meter head, you can calibrate the voltage and current error by yourself.Two-wire system: no need to connect the power supply, the red and black wires are connected to the meter while supplying voltage (no polarity is required)Current testing does not require the purchase of a separate transformer. The meter comes with a high-precision transformer.The split-type transformer has a back cover that is safer, more convenient, and more secure! ! !Specification:Working temperature: -10 ~ +50 °CWorking humidity: 10~80% (no condensation)Working pressure: 80 ~ 106kPaMeasurement accuracy: 1% ± 2 wordsMeasuring speed: about 2 times per secondDimensions: 70 × 40 × 30 mmInstallation size: 68×38mmPower supply line, measuring line length: about 150mm"Separate" transformer lead length: about 100mmNote:1. The wiring sequence of the instrument is: first connect the current circuit line, 220V voltage is last connected, after turning on the 220V power supply, you can not touch any components and circuits behind the instrument to prevent electric shock.2. This table is designed using the principle of capacitor buck. The higher the frequency, the smaller the impedance of the capacitor, so it is not suitable for high-frequency electronic speed regulation, non-mains sine wave frequency, or other high-frequency components. Otherwise Easy to burn!!!

• Working temperature: -10 ~ +50 °C. Working humidity: 10~80% (no condensation). Working pressure: 80 ~ 106kPa. Power supply line, measuring line length: about 150mm. "Separate" transformer lead length: about 100mm.
• The multimeter can clearly display voltage and current at the same time, dual display, highlight large font.
• Current testing does not require the purchase of a separate transformer. The meter comes with a high-precision transformer. Can be installed on anywhere flexibly.
• Two-wire system: no need to connect the power supply, the red and black wires are connected to the meter while supplying voltage (no polarity is required).
• Simple wiring of the instrument: Set the trimmer potentiometer in the meter head, you can calibrate the voltage and current error by yourself.
