What makes you select this LED digital voltmeter ammeter?
-With its compact design, it is easy to store and carry, ensuring convenient access at any time.
-It measures accurately with the margin of error for voltage measurement being 0.1%, and the margin of error for current measurement being 1%.
-This digital voltmeter ammeter allows you to monitor your vehicle's voltage and current levels accurately and in real time, making it an essential tool when traveling.
How to use this digital voltmeter ammeter?
-When connecting the 1-10A meter head for direct power supply, connect the black thick wire to the negative pole of the power supply, and the red thick wire to the negative pole of the load. Connect the thin red wire and the thin yellow wire between the positive pole of the power supply and the positive pole of the load, and the thin black wire does not need to be connected.
-When connecting a 1-10A meter head with an independent power supply, connect the black thick wire to the negative pole of the power supply, and the red thick wire to the negative pole of the load. Connect the thin red wire and the thin black wire to the power supply, and the thin yellow wire between the positive pole of the power supply and the positive pole of the load.

Very accurate and multiple simple ways of use.Applied 12V and 1A via my bench top power supply and this read precisely what it was fed; varied input by 20% and it corrected as expected.Using this in a project enclosure to monitor fluctuations in a fan controller during startup versus runShould be very useful for real time data on that system.Screen is bright, but not too bright, easy to read from 6 feet away with my aging eyes.

Nice meters. I use this to easily test the amp draw of various devices on my bench. I like to test LEDs, radios, and other small devices before I install them on my jeep or tractor. This is an easy way to monitor them while testing pre-install.I use it inline with my power supply/ battery and it works very nicely. The volt meter is fairly accurate and matches my cheap multimeter set to volt.
