MakerFocus 2pcs Digital AC Voltage Meter 0.39inch AC100V~300V/0.00~50A
1. This voltage and current display meter is installed in split type . Split type: Convenient to installation, and the transformer is separated from the instrument.Transformers can be installed according to the actual position measured (the lead of the secondary end of the transformer can be lengthened to achieve the desired installation position);
2. The wiring order of the meter is: First connect the circuit of the current loop, 220V voltage is finally connected, After turning on the 220V power supply, It is not possible to touch any components and circuits on the back of the instrument to avoid the risk of electric shock.
3. This meter is designed based on the principle of capacitance step-down. Because the higher the frequency, the smaller the impedance of capacitance, it is not suitable for high frequency electronic speed regulation, non-commercial sinusoidal frequency, or other occasions with high frequency components. If you use in these situations , it is easy to burn out!!!
4. Installation method - split type: The green terminal is connected to the AC transformer CT, and the two yellow lines are connected to measure the AC voltage. Do not connect incorrectly. If the connection is wrong, it will cause instrument damage. Responsibility at your own risk.
