Review on 🔌 KETOTEK AC Voltmeter Panel Mounting Meter AC80-300V Frequency Counter 45.0-65.0 HZ LED Display Voltage Volt Frequency Meter Tester Gauge by Robert Buenconsejo

I bought this meter for an old generator that I wanted to restore. I installed this meter on the alternator to monitor voltage and frequency and to set the engine governor. It's impractical to test your portable generator with a multimeter every time you need it during a power outage, and it's nice to make sure its output is correct before you power it up and risk blowing up sensitive equipment . I have tested this meter for accuracy with my Fluke multimeter and it is very accurate. The hardest part of the installation was cutting a square hole in the panel with a cutting wheel and sawing it to the desired final size.
