Notice: This product is not for use with high frequency speed regulation, non-city electricity sine wave frequency or any other application including high frequency operations. As it may damage the meter.

The idea behind this meter is that you will use it in your home or industrial application to measure the voltage and frequency to ensure your mains input is with in specification. Or use on your permanent home, or portable generator to ensure it is preforming properly. Do not use with inverters, or inverter generators that are not pure sine wave. Works very well with older style generators.
