Test Sequence with Connection to the Test Socket
Set the rotary switch to the R
PE
position.
Sel
ect measurement type or connection type, and test cur-
rent. After pressing the Ip k
ey, you have direct access to the
test current parameters: each time this key is pressed, the
setpoint value shown in the measuring window is switched to
the next value.
Connect the D
UT to the test socket.
Start the test: press the START/STOP key.
Contact all conductive parts which are connected to
the protective conductor with test probe P1.
During measurement, the connector cable must
only be moved to
the extent to which it’s accessible during repair, modification or
testing.
If a change in resistance occurs during the manua
l test step of the
continuity test, it must be assumed that the protective conductor
is damaged, or that one of the connector contacts is no longer in
flawless condition.
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.
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.
Read
the measured values and compare them with the
table of permissible limit values.
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.
Special Case: Testing Extension Cords
Set the measurement type parameter to “PE(TS) – P1”.
Connect the EL1 adapter to the P1 sockets at the test instru-
ment.
Connect the pl
ug 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.
Sam
e test sequence as described above.
Further options for testing extension cor
ds are included in the
description of single measurements in the EL1 switch position
and under automatic test sequences in switch position A8.
Special case: permanently installed DUT
Contact all conductive housing parts with test probe P1.
Special Case: Testing Protective Conductor Resistance at PRCDs
(as of firmware V1.4.0)
For PRCDs whose protective conductor resistance cannot be
measured when switched off, the SECUTEST BASE(10) offers the
“a
ctive: PE(TS) - P1” measurement type, with which the PRCD
can be switched on in order to ascertain protective conductor
resistance.
Se
t the measurement type parameter to “active: PE(TS)
P1”.
Connec
t the EL1 adapter (or alternatively a normal test probe)
to the P1 sockets at the test instrument.
Co
nnect the plug of the PRCD under test to the test socket.
Connec
t the EL1 adapter to the outlet on the PRCD (alterna-
tive: connect the test probe to the
protective conductor of the
PRCD’s outlet, e.g. by means of an alligator clip).
Start the
measurement.
S
witch line voltage to the test socket. Then switch the PRCD
on.
Other
wise, the test sequence is the same as described
above.
Note
With the +200 mA=, –200 mA= and ± 200 mA= mea-
surement types, test current rises ver
y slowly in order to
prevent triggering of residual current monitoring at the
PRCD. And thus with this measurement type, it may take
longer than usual until a valid measured value is dis-
played. For this reason, the protective conductor should
no
t be contacted manually with the test probe, in order to
prevent a sudden rise in test current resulting in inadver-
tent tripping of the PRCD.
