Digital Voltmeter Ammeter DC 0-100V 10A Dual LED Monitor Panel, Red and Blue

This Red-Blue LED Digital Dual DC 100V 10A Ammeter Voltmeter is designed explicitly to measure the magnitudes of voltage and current displayed on the same screen at the same time. This dual DC ammeter voltmeter is one of the prominent devices used by an electronics technician. This portable Digital Voltmeter, measure up to 100 VDC with a 0.1-volt resolution and consumes less than 20mA. Whereas the ammeter can measure at a range of 0A to 10A with a resolution of0.01.

This is a highly accurate and compact-sized digital ammeter voltmeter that comes with an  LED Display. The Red display indicates the voltage measurement, whereas the blue indicates the current measurement This module uses a 0.28-inch digital tube display, with a super small volume for voltage and current measurement. This display panel meter has 2 wiring harnesses. One harness is poles with a RED and a BLACK lead to provide power for the meter. The other harness with 3 wires used for current and voltage measurement.

This module is powered within a range from 4.5 volts DC up to 30 VDC. This is a separate power supply that is isolated from the source, it is possible to use the same supply but it seems to affect the amp meter reading. Meanwhile, the 3 wire harness is used to connect the ground directly to the battery or supply ground of the load. Its highly recommended that input voltage should not exceed 30V, else there is a chance for burning.

Wiring:-

• Blackline (thin): vacant or buck circuit (module) Negative
• Redline (thin): power supply Positive
• Blackline (thick): COM, common measuring
• Redline (thick): PW+, measuring terminal voltage input positive
• Yellow line (thick): IN+, current input Positive
