Your satisfaction is my pursuit.
Glad to serve you, meet is a fate.

Product introduction:
This product is a combination of a pointer ammeter and a shunt.Shunt is actually a very small resistance, when there is DC current through, produce voltage drop, for DC ammeter display.
The wiring mode of the product can refer to the pictures on the home page.
Ammeter is equipped with a separate package of accessories (2 cross round screws, 4 flat pads, 4 nuts, 2 spring pads).
Wiring tools for connecting the ammeter to the shunt will be purchased separately.
Advantage:
Pointer type instrument is a traditional industrial craft, all handmade.
Black plastic case. Very lightweight, easy to install and easy to connect.
The reading is very convenient, suitable for use on some cabinets, can directly observe the change of current.
When used together with the shunt, the power consumption is safer and the instrument is not easy to be damaged.
Caution:
There are four bolts on the shunt, two large and two small. Use two large bolts to connect the shunt in series to the circuit of the current signal to be measured.
Two small bolts are connected to the signal input terminal of the instrument. Pay attention to the polarity of the signal. The end where the current flows into the shunt is the positive end, which is connected to the positive input terminal of the signal input terminal of the instrument.
The end where the current flows out of the shunt is the negative end, which is connected to the negative input end of the instrument signal input end.
