Blue Sea 9354 AC Analog Voltmeter 0-250 Volts AC consumer electronics Electronics

well I'll just do a quick review and tear down of these little AC panel meters that I got recently they come in little box like that they're called digital panel lights I've got a blue one and a green one and they show voltage and current and just just to see what they look like turn them on and they're quite bright pretty displays and they have a circular mounting hole and I'll just measure that 20 millimeters that way and 21 millimeters that way so there's a flat spot that's not at rotating and they use current transformer so you just stick the voltage to run the meter in there the mains voltage and since the time ever current transformer like that I'll just connect this one will just play the blue one all right so I'm running it from the very act and then also into this dummy load to measure it to tick out the current sensing so you just bring the voltage up and we'll see that it don
