… the wiring instructions are hopeless, and quality control is very suspect.Fortunately there are a lot of good videos on YouTube showing how to wire the meter, and this makes up for the lack of clarity in the product instructions.One of the meters worked perfectly. The other did not. When connected to a known 12v source, it showed 24v and a current fluctuating temperature between 0 and 4 or 5 amps, even though the ammeter connection wasn’t connected to anything. Returned to Amazon for refund, but an identical pair ordered; hopefully a pair that had better QC.

Used on an old variable Voltage / Current PSU to monitor from 4.5V to 30V, PSU current up to 3A. The original analogue meter movement has given up the ghost (after 50 year), I boxed the meter, did some simple wiring, made banana cables, added connectors. Now have a state of the art PSU! The original PSU A/V controls still work. A very cheap fix. The only issue is the retaining clips, because of the size of the PCB components the clips will not retract, this made fitting the meter in the box more difficult.

They need a shunt to work. Most have these built in but these just have an empty space where one should be. No instructions and no labels on the wires ether

Unfortunately, previously installed unit lost part of display after a short time, so needed replacement. Hence purchase of 2 , 1 as spare. Thankfully they are cheap.

Does what I wanted and for a good price! Thank you.

Seems roughly accurate and does the job

Nice and professional looking, as an addition to something like a simple power supply project.Not bad at all for the price.The voltage remains steady and is really quite accurate (+/- 2%) but the Amps 'wander' around a bit and may only be about 90% accurate, so not good at all for measuring or indicating mA loads.One more digit for a higher voltage resolution would've been better, but good enough for basic volts/amps indication.I would've preferred some proper terminals so I could connect my own cables, as the ones supplied with the tiny plugs fitted are very short, and they seem to be a bit delicate for using at up to 10A.Otherwise a nice compact size, quite practical and very smart looking when fitted into an enclosure.Very good value.

Ottimo prodotto Precisione nella lettura ,prezzo ottimo .Cablaggio poco intuitivo consiglio di scaricare dal sito le istruzioni inerenti al prodotto.

fotoğraftaki gibi arkasında iki adet ince ayar düğmesi yok, sadece voltaj için ince ayar düğmesi var, akım (amper) için ince ayar düğmesi yok. ama tanıtım fotoğrafında ikisi de var/bu yanıltıcı ve aldatıcı

Lo he usado para controlar la carga de batería de respaldo.

Redelijk goede kwaliteit van het product. Doet wat er van verlangt word. Jammer dat er geen aansluitschema bij is. Dit moet men separaat opzoeken op internet. Snelle levering.

The Voltmeter part of the display is OK, but the Ampere-meter is grossly unlinear and this must be related to the ADC of the instrument.I would NOT recommend you to buy it.
