Active screening/phase tester
Phase test:
Plug the tip of screening tester into both of the holes (alternately) in the plug socket and
then let go of the screening tester. The hole in which the screening tester lights up (LED)
is the phase. Plug the mains plug from the AC-A1016 active power distributor into the plug
socket so that the white indicator dot on the plug is aligned with the phased hole of the
plug socket. We also recommend that you mark the phase hole on the plug socket.
CAUTION:
The screening tester is not suitable for determining whether the plug sockets
and the devices are de-energised! Work on electrical devices and installations should only
be performed by a qualified electrician.
Screening test:
Hold the screening tester firmly by the tip and run it along the length of the cable to be
tested. If the screening tester lights up, the cable is not screened
Note:
This only works, of course, with 230V power cables which are also plugged in /
switched on!
Polarity test:
You can also use the screening tester to test whether lamps and devices with cable
switches are plugged in in the right direction. The switch should switch the phase, not the
neutral conductor. Switch off the lamp and run the screening tester along the length of
the cable. It will light up in front of the switch, and go out behind the switch. If not, rotate
the mains plug and test the cable again. This can be done to reduce electromagnetic
pollution in your environment, as well as to reduce the “load” on your hi-fi components.
