Note:
if measure the current over than 5A for long time. please welding the wires to the meter port, to avoid High impedance and unstable working.
Wire Connection:
Thin Red line (VCC): Power Supply + (DC 3.5-30V +)
(if the measure voltage between DC 3.5-30V, then the Thin Yellow line and Thin Red line can connect together)
Thin Black line (GND): Power Supply - (DC 3.5-30V -), Measure Voltage - (DC 0-100V -)
Thin Yellow line (VIN): Measure Voltage + (DC 0-100V +)
Thick Red line (I+): Current Input +
Thick Black line (I-): Current Input -
