diymore Digital Ammeter Voltmeter 2PCS DC 100V 50A LED Volt Meter Voltage Current Amp Blue + Red Dual Color Display Multimeter Amperage Meter Volt Amp Gauge Panel with 50A Current Shunt

Good value meter, good enough for my projects.

Volts read perfectly and check out against two other multimeters. Despite being connected correctly, the amps read way too high, checked via a calibrated dummy load and other meters. 10 real amps read 33A. I checked the whole range up to 20A and got readings consistently over 3x actual.

The one that arrived is great, BUT only one arrived. Amazon do not have an option to cover short orders.What do I do to get the other one i paid for?

Using several of these. Instructions?? Why they use the Neg cannot say. Take care with the wiring Red/Yellow, tried going over 30 volts & bad news.Watch this space

Second order where item was faulty no Current Display

Both working, now know amps going in battery & with DPT switch amps on load.

un petit schéma de raccordement serait le bienvenu....

The voltmeter works fine, but the provided shunt is not the good value, so that the read current is 5x less than the actual current. i.e. A current of 10 A is read as 2.00 A.So to have an accurate current reading, you will need to buy two replacement shunts rated 7.5 mohm, or 75 mV / 10 A (as currenty rated on chinese websites)EDIT: Later tests indicate that it is not at all abe to read voltage up to 100 V. It goes up to max 32 V, and at around 40 V, it blows up. I'm referring to the measured voltage, and not the power supply.Unfortunately, I cannot send them back, it's too late, but DO NOT BUY, they do NOT meet the announced characteristics ! This is not the first problem I have with the seller "diymore" and I wil avoid him in the future.EDIT2: Several months later, the seller proposed spontaneously a full refund, which I accepted. I therefore changed my review from 1 star to 4 star, because this shows that the seller really does his best to satisfy his customers 👍👍👍

Después de recibir el ultimo pedido con los medidores defectuosos se han puesto en contacto conmigo para intentar resolver la incidencia.Sorprendido para bien. Y agradecido.

facile à mettre en œuvre et à intégrer dans un tableau, précision suffisante pour mon utilisation, i.e. surveiller les alimentations d'un simulateur.

Preciso al decimo di volt confrontando con multimetro professionale, bisogna fare attenzione al circuito allegato, se con alimentazione separata o non.Purtroppo mi sono arrivati due prodotti diversi e uno non funziona.
