Review on πŸ“Ÿ LM YN Digital AC Voltmeter: Accurate Voltage and Frequency Testing with LCD Display - 2 in 1 Meter Tester by Mark Toth

Revainrating 5 out of 5

Great Meter - Testers

Bought to measure the frequency of my backup generator. I live on a ranch and the power goes out all the time. I have found that my alternator frequency is around 60.5Hz at light load and around 59Hz at full load. I find that very reassuring. I connected the meter when I had AC power and it ran stable at 60.0Hz. Good calibration check.

Pros
  • handy item
Cons
  • questionable purchase for the elderly
