Measuring Parameter Meaning
Connection Type
EL1 adapter Measurement with EL1 adapter and DUT at test
socket for single-phase extension cords
AT3-I I I E adapter Measurement with AT3-I I I E adapter 
for single and 3-phase extension cords
VL2E adapter Measurement with VL2E adapter 
for single and 3-phase extension cords
See corresponding single measurements for the testing of RPE
and RISO.
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 RISO 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 i
ndicating the correctness of
the extension cord’s polarity cannot be relied upon!
Note
In conductors with control lamp (usually glow lamp in the
switch), the result of the continuity test for L and N may
be distorted by the additional resistance of the glow
lamp.

In case of doubt, we recommend pe
rforming a continuity
test for L and N by means of resistance measurement (R-
PE or R-ISO): 
SECUTEST PRO: R-PE between probe 1 and probe 2.
SECUTEST BASE(10): R-PE between probe 1 and measure-
ment cable at the earth contacts
of the test socket (test
type PE(PD)-P1).
Test Sequence with EL1 Adapter
➭ Set the rotary switch to the EL1 position.
➭ Select the EL1 adapter connection type directly via the
key shown at the right. 
➭ 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 sock
et at the end of the extension cord
to the plug at the EL1 adapter.
➭ S
tart the test: press the START/STOP key. 

➭
The measured values are displayed. The measured
value recording symbol shown at the right appears.
Each time th
is key is pressed, the currently displayed
measured value is saved to the buffer.
➭ S
top 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.
➭ P
ress the ESC key in order to discard the measured
values stored to buffer memory and acknowledge by
pressing the key shown at the right.
Test Sequence with VL2E Adapter
➭ Set the rotary switch to the EL1 position.
➭ Se
lect the VL2E adapter connection type directly via the
key shown at the right.
➭ Connect the cable from the VL2E adapter to the test socket at
the SECUTEST....
➭ Connect the extension cord’s plug and socket to the VL2E
adapter.
➭ S
tart the test: press the START/STOP key. 

➭ S
et the rotary selector switch on the VL2E adapter to position
2 and retain this position.
The measured values are displayed.
Note
The test instrument only indicates whether or not the
cable is OK or not OK. In the case of “not OK”, the inspec
-
tor has to determine whether or not an interruption or a
sh
ort-circuit is involved on his own by means of further
measurements.
➭ 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 pr
ompts you to save the measured values to an ID
number.
➭ P
ress the ESC key in order to discard the measured
values stored to buffer memory and acknowledge by
pressing the key shown at the right.
Test Sequence with AT3-I I I E Adapter
Attention!
!
Please observe the operating instructions for the AT3-
I I I E regarding correct connection of th
e test adapter and
the device under test, as well as peculiarities involved in
the test sequence.
