2 in 1 DC 0-100V 50A Voltmeter Ammeter With DC 50A 75mV Ampere Shunt Dual 0.28″ Red Blue Voltage Detector Current Indicator

2 in 1 DC 0-100V Voltmeter Ammeter With DC 50A 75mV Ampere Shunt Dual 0.28″ Red Blue Voltage Detector Current Indicator

It is a 2in1 Digital Meter/Voltmeter Ammeter, Voltage Measuring Range: DC 4.5~100V, Current Measuring Range: 0.0~50.0A, It has small size, high efficiency, long term stable and reliable quality, easy installation and use. Suitable for monitoring storage battery, DC adjustable power supply, or voltage and current changing state of other device.

Connecting Method:

• COM: Common terminal of power supply negative pole
• V+: Positive pole of tested voltage, positive pole input terminal of power supply
• A+: Positive pole input terminal of tested current ( This meter adopts common-ground design that earth wire of measuring terminal is interlinked with earth wire of power supply, so A+ only can be connected between the tested device negative pole and power supply negative pole. the meter will be burnt if connected wrong.)
• Note: If the meter is just used as voltmeter, it is suggested that the yellow wire and black wire are connected together.

Features:

• Reliable and dustproof case
• 0.28 inch mini display
• This meter is provided with 3 wiring terminal, when testing voltage and current, the power comes from the return circuit, so you don’t need extra power supply.
• This meter adopts common-ground design that earth wire of measuring terminal is interlinked with the earth wire of power supply, so the meter only can be connected in series between the tested device negative pole and power supply negative pole when testing current.
• It has voltage calibration potentiometer and current calibration potentiometer, if there is an error, you can adjust them by yourself.
• This voltage current meter adopts 0.28″ LED display, voltage shows red and current shows green; the decimal point can move automatically.
• With strong anti-interference capability, it can quickly display refresh rate; with exquisite SMT technology, it has good consistency.
• This meter has handy connection and wide application, for example, it can be applied to monitoring storage battery, DC adjustable power supply, or voltage and current changing state of other device.
