Reminder: Please refer to the instructions below and the wiring diagram before purchase and installation. Otherwise, wrong purchase, incorrect wiring, or improper use will directly cause damage to the meter head.
Product features:
?This two-color dual-meter is small in size and can display voltage and current on the same screen at the same time.
?This meter adopts a common ground design, that is, the ground wire of the measurement terminal and the ground wire of the power supply terminal are connected.
?The power supply range of this meter £ºDC4.5~30V, the reverse connection of power supply will not burn. Note: The maximum power supply voltage cannot exceed 30V, otherwise there is a danger of burning.
?This meter is equipped with five wires for easy access to the measurement circuit for voltage monitoring and timely Grasp the voltage status, current changes, etc.

Wiring instructions:
This watch is equipped with five wires. Please find a professional to connect it strictly according to the following wiring diagram. If you have any questions, please feel free to contact customer service:
?The power supply of the meter head: two-wire socket
thin-black wire: the power supply ground of the meter head
Thin-red wire: the power supply of the meter head is positive (Note, the voltage between the thin red and black wires cannot exceed 30V)
Test terminal: three-wire socket\COM ??black wire: test common terminal\PW+ ??red wire: measuring positive voltage input terminal\IN+ ??yellow wire: current input terminal; because the meter head adopts a common ground design, that is, the ground of the measurement terminal The wire is connected to the ground wire of the power supply terminal, so it can only be connected between the negative of the device under test and the negative of the power supply. Connect the wires together to prevent external interference from causing the ammeter to flash)
Note, please install the wiring diagram strictly. The current measured by this meter must be connected in series with the negative line of the circuit, otherwise the IC will be burned out.
