5-9 EF (Electric Field ) sensing
①
The EF sensing judges the presence of electrical voltage in a simplified
manner by detecting the electrical field produced by AC voltage.
②
When the
button is pressed while a function other than voltage or
current (other than

The EF sensing is canceled by pressing the
button or changing
the function switch position.
③
The signal intensity is displayed by segments such as “- - -“. The interruption
