Review on π KETOTEK AC Voltmeter Panel Mounting Meter AC80-300V Frequency Counter 45.0-65.0 HZ LED Display Voltage Volt Frequency Meter Tester Gauge by Dre Fowler
Not so accurate best among voltage testers
Voltage seems accurate and matches my calibrated Simpson 260. On the other hand, it takes over 30 minutes for the frequency to warm up and get a stable reading. Unfortunately, for a grid that registers 59.5 Hz, it is not accurate and does not register 60.0 Hz, which my other meter does. It's a pity that there is no calibration pot for it to be able to make it more accurate in the field.
