DC 0-100V 50A 100A 0.28" Mini Digital Voltmeter Ammeter 3 Bit 5 Wires Voltage Current Meter Tester Blue Red Dual LED Display DC 4-30V 5V 12V

Specification:

Voltage below 10V can be measured and displayed as 0.00V;
The current test starts from 0.05A, when the current is less than 0.05A, it displays 0.00; the current is not forced to zero;
350A, 100A range measurement is less than 10A current can also display 0.00A, but the error of the last digit is large, for reference only and can be ignored.
Note: ①The current below 0.05A cannot be measured. ②When the test is 50A100A, it can also display 0.00A below 10A.
However, the error is relatively large. When using a 50A/100A range meter to measure current below 10A, the last digit must be ignored.

Wiring Diagram:

Black - Red : Working voltage of Meter itself: DC 4 - 30V
Black - Yellow : Voltage Measuring range: DC 0 - 100V

Reverse connection protection: there is reverse connection protection of working power supply, but long time reverse connection may also cause damage.

Product wire: 5 wires (3P thin wire, 2P thick wire)

Lead definition:

Thin red line: positive pole of instrument power supply
Thin black wire: the negative electrode of the power supply of the instrument is also a common ground wire
Thin yellow wire: measuring voltage positive
Thick red line: the positive pole of the current test, in series with the negative pole of the load
Thick black wire: the negative pole of the current test, connected to the negative pole of the load power supply

Note: The 50A/100A meter does not contain a shunt. The shunt is purchased separately. It cannot be used normally without a shunt.

Package Included:

1 * DC 3-digit Precision Dual Display Voltage Current Meter
