Contact all exposed, conductive parts with the probe.
The test can be repeated as often as desired for various protective
conductor parts with the manual sequence.*
* If it is not clear whether or not all
exposed, conductive parts are con-
nected to one another or to the
protective conductor, testing can be
performed in the manual mode.
