Review on 🔌 MNJ Motor LCD Display Digital Multifunction Meter, Voltage Amperage Power Energy Frequency Power Factor Multimeter Ammeter Voltmeter - AC Current 80-260V, 100A with Split Core Current Transformer by Russ Mashlan

I have it put on the jacuzzi (240V). I wasn't sure how to do it. I googled a lot. The spa has 4 wires, red, black, white, ground. I put a reverb effect over black. I put two more lines on red and black. I understand that I'm missing a neutral (white) color between white and red or white and black, so I'll have to contact the hot tub manufacturer. However, it reads 11 amps when the pump is on and 0.5 amps when only the heater is on, so I think it's working. I've always wanted to know what my hot tub really costs. Now I know the terrible truth. in a month or so.
