Operating voltage:DC 4.5 ~ 30V
Measure voltage: DC 0 ~ 100V
Minimum resolution(V): 0.1V
Minimum resolution(A): 0.01A
Operating current: Display: three 0.28" LED digital tube
Display color: Red and Blue (two-color display)
Dimensions: 48 x 29 x 21mm
Mounting cutout: 45.5 x 26.5mm
Refresh rate: about 500mS / times
Measure accuracy: 1%
Operating temperature: -10 to 65ºc
Operating Humidity: 10 to 80% (non-condensing)
Working pressure: 80 to 106 kPa
Applications:Suitable for automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement
Wiring:
Black line (thin): vacant or buck circuit (module) negative
Red line (thin): power supply+
Black line (thick): COM, common measuring
Red line (thick): PW+, measuring terminal voltage input positive
Yellow line (thick): IN+, current input+
(Please refer to the wiring diagrams for more details)
Note:
The voltage between the thin red and thin black
lines must be within DC 4.5-30V
The ammeter can only be connected to the negative of the device under test
10A below ammeter (include 10A), built-in shunt, does not require external shunt
When the black thin line vacant, it is better to use insulating tape around the exposed part of the wire, to prevent short circuits
If just be used as a voltmeter, it is recommended that the yellow line and the black line were connected together, to prevent the ammeter digital flashing
Package Include:
6 x Digital Volt Ampere Meter
12Pcs Cable

Very handy for my variable voltage/current power supply and battery charger projects.These are an exceptional value.

The pictures of the product clearly show a builtin shunt, but it is missing on the actual product.

I like the accuracy. The display is bright clear. Only caution is don't hook up the two thicker black and red wires to positive and negative, it will blow up, you have to run the amp meter on ground wire only. Also small black wire not connected for more accurate measurements. The thick black wire goes to ground, and the other thick red wire connects directly to your load negative to measure current. Of course you will need to hook up the smaller yellow and red wires to positive on your power DC source for your meter power.

They work. Haven't had any issues.WARNING: They are NOT water-resistant so don't use them in a wet environment (boats/motorcycles, golfcarts).

If they came with instructions I'd probably love them. But I hate them and resort to endless YouTube videos. The one I managed to hook up for amperage is not accurate id be better at guessing than The lies it displays. Wiring is confusing no diagram or instructions not accurate.

I use this for battery calibration Some work some don't

Very simple and small size, but description shows 2 decimal readout on voltage and these display only 1. Also, It states the 2 pin connector uses thin wire and the 3 pin connector uses thick wire. This is reversed, the wires do match the pictures. Doesn’t meet my needs so I’ll be returning.
