8.10 Testing Extension Cords – EL1
Schematic Diagram
Setting Measuring Parameters
See corresponding single measurements for the testing of RPE
and RINS.
Note
See section 10, “Test Sequences in Accordance with
Standards” (switch setting A8), with regard to testing
extension cords per DIN VDE 0701-0702, for which RPE
and RINS are measured.
Attention!
!
If the EL1 continuity test is conducted for an extension
cord in combination with a “travel adapter”, results pro-
vided by the test instrument indicating the correctness of
the extension cord’s polarity cannot be relied upon!
Test Sequence
Set the rotary switch to the EL1 position.
Connect the EL1 adapter to the P1 sockets at the test instru-
ment.
Connect the plug at the end of the extension cord to the test
socket.
Connect the coupling socket at the end of the extension cord
to the plug at the EL1 adapter.
Start the test: press the START/STOP key.
The measured values are displayed. The measured
value recording symbol shown at the right appears.
Each time this key is pressed, the currently displayed
measured value is saved to the buffer.
Stop the test: press the START/STOP key.
The save symbol appears (floppy disk showing the
number of measured values stored to buffer memory)
and prompts you to save the measured values to an ID
number.
Press the ESC key in order to discard the measured
values stored to buffer memory and acknowledge by
pressing the key shown at the right.
