Description
DC0-100V /10A Digital Multimeter Dual LED Display Voltmeter Ammeter Voltage Current Meter Volt Amp Panel Monitor
Product Description
Features
The function is perfect and integrates the voltage and current meter. When measuring the current, the power supply is taken from the measuring circuit. There is no need for an isolated power supply for independent power supply, which is convenient to use. The small size (48mm*29mm*22mm) is believed to be the smallest voltage and current meter on the market.

Installation Instructions
Function description of onboard wire
Thin red wire (VCC): power supply input positive (3.5-30V) Note: If the measurement signal is lower than 30V and the power supply is sufficient, it can be directly used as the power supply of the module (use the thin yellow wire and the thin red wire in parallel) Thin black wire (GND): the negative electrode of the power supply input (3.5-30V) and the measurement signal are in the same ground Thin yellow wire (VIN): measurement signal input positive (0-100V) Thick red wire (I+): Current input positive (must be connected in series with the negative power supply) Thick black wire (I-): negative current input (must be connected in series with negative power supply)
