BAOMAIN DH-670 DC 0-50A Analog Amp Panel Meter Current Ammeter with 50A 75mV Shunt Resistor, Class 2.0 Accuracy, Mechanical Pointer Gauge for Battery Charging & Solar Systems

These panel meters were tested and found to function properly. The display is clear and easy to read. The panel meters are plastic encased and lightweight. Our friends in China at Baomain have once again produced a quality product at an affordable price. These meters arrived along with two volt meters from Baomain and the packaging was better than I see from most domestic shippers. Four outer layer of bubble wrap invidually boxed inside a larger box with foam and even foam inside the individual meter boxes. These came direct from China so allow some time for delivery which includes delay at our USPS International Sorting Centers.

I have now a mix of four of this brand's meters and they are all nicely done for a budget price.

Very good setup, works great for my current measurements. Good cost and fast shipping. Happy with purchase.

Meter was accurate right out of the box. Checked with true RMS meter. Although, it is adjustable. This meter has no built in lights. I used my own shunt, though the one that came with it is fine.

I would have given it 5 stars, but i ended up having to calibrate the shunt to the meter. This should have been done by the factory. no where in the ad did it say this had to be done. Good thing for Google...... Seller should let buyer aware of this.

Used to replace broken meter in an older battery charger. Slight modification to mounting opening. Works as it was intended.

Made a homemade shunt tester for small engines and testing the charging systems. Seems to work just fine. Thanks.

Received in a timely fashion did not work had to return it to get another one

The first thing that you need to know is how to properly connect an ammeter, which is in parallel with the shunt. Connect the positive lead from the battery to one end of the shunt. Connect the other end of the shunt to the load, i.e., the appliance, that you are powering. At this stage your appliance will work like before. The only difference is that current flows through the shunt instead of directly through the wire. Now, connect the meter to the shunt. The back of the meter is marked plus and minus. Connect the plus post to the same side of the shunt to which you connected the positive lead in the first step. Then, connect the minus post to the other end of the shunt, where you connected the wire carrying current in step two. If you are careless and connect the leads the other way around the needle may swing the wrong way and damage the meter. The diagram is for a voltmeter and an ammeter, as I installed both to monitor output from my solar array. The meter seems to be good quality with an attractive appearance and is easy to read. Also, easy to install. It is easier and more accurate if you first make a paper template and then use it to properly position the meter and drill the holes.

Mala calidad del grabado de números, se borran al limpiarlos. No recomiendo

Excellent value for the price.

Fonctionne très bien. Monté (la photo) sur un support en bois.
