•  Long press it, cancel the setup or exit.

1. The meter can only be used to measure 45/65Hz sine wave circuit,it will be damaged when use to measure square wave,output of inverter and correction sine wave.

2. When selecting the range, the larger the range, the larger the deviation. It is suggested that the range is 1.5 or 2 times as large as the actual measuring value .
