New DC Digital Voltmeter Ammeter LED Amp Volt Meter + Current Shunt

The module has reverse polarity protection, even if it will not damage the module reversed.

50A and 100A ammeter scale accurate to 0.1A, 10A ammeter less accurate to 0.01A, voltmeter accurate to 0.1V.

Instructions:
The ammeter power supply terminal and ground using common measuring terminal to design, that is, the power supply side of the ground and the testing ground is the same, so the test ammeter in series with the electrical terminal only after (ie, the device under test the anode and cathode power between the device under test)
Recommends using a separate header isolated power supply terminal

Before using shunt must first access the circuit and then draw digital ammeter head to prevent pressure damage to the meter.

Before using shunt must first access the circuit and then draw digital ammeter head to prevent pressure damage to the meter.
Lead Definition (5 lines)



Thin black line: negative power meter
The Thin Red Line: Header powered anode (thin red and thin black line between the voltage 4-30V, over shall be burnt)
Thick red line: measure the positive voltage input (this line and the thick black line is the voltage between the voltage meter display)
Thick yellow line: measure current flow leads.
Bold lines: measuring current flow leads (thick black line and the thin black line is the common ground is connected)
