Gossen MetraWatt SECUTEST ST BASE - Testing Extension Cords for Correct Function - EL1

72 Gossen Metrawatt GmbH
15.13 Testing Extension Cords for Correct Function – EL1
* No checking for reversed wires when the EL1 adapter is used
Attention!
!
This function permits an evaluation of the continuity of
the extension cord’s active conductors L(1, 2, 3) and N.
The PE conductor isn’t tested in this case.
