Gossen MetraWatt SECUTEST PRO - Testing Extension Cords for Correct Function - EL1

54 GMC-I Messtechnik GmbH
8.12 Testing Extension Cords for Correct Function – EL1
* No checking for reversed polarity takes place when the EL1 adapter is used.
Attention!
!
This function permits an evaluation of the continuity of
the active conductors L(1, 2, 3) and N of an extension
cord. The PE conductor is not tested in this case.
