disabled:
all classification parameters such as connection and protec-

These parameters must be entered manually if they’re not automatically
detected, or if they’re detected incorrectly.
Note
As from firmware version 2.1.0, the limit values in the test
instrument are set at IEC 60974-4:2016 status.
Sequence Parameter (as of firmware V1.3.0)
The default test sequences can be adapted to your applica-
tion or test standard via the se
quence parameter. The entered
sequence parameter settings are only valid for the currently
selected switch position (A1 to A8 or AUTO) and are retained until
they are changed. Not all of the parameters are relevant, depend-
ing on the selected DUT classif
ication (protection class etc.).
❑ Suppr
essing Test Steps
Depending on the selected test standar
d, some of the following
test steps can be suppressed:
Parameter Suppressible test steps
Visual Inspection Visual inspection standard
Visual Inspection 2 Visual inspection function test welding equipment
Function test Function test
RPE Protective conductor resistance test
RISO PC I+II Insulation resistance tests for PCI and PCII
RISO pri./sec. Insulation resistance test between the primar
y and 
secondary sides of PCIII DUTs
RISO sec./PE Insulation resistance test between the secondary side and
PE
of PCIII DUTs
RISO BF/CF
(IEC 62353)
Insulation resistance tests at BF/CF application parts
RISO welding circuit
(IEC 60974-4)
RISO tests between the primary side and the welding 
output, as well as between PE and the welding output
Reversed polarity All leakage current measurements with reversed polarity

IB Touch current test
IB welding circuit Touch current test at welding circuit
Display test instructions Test instructions which are not necessarily required for experi-
enced inspectors
Short-circuit test L-N Short-circuit test between L and N

Before switching line voltage to the device under test, a short-circuit test
is conducted regardless of this setting.
❑ Setting Measuring Parameters for Individual Test Steps
Depending on the selected test standar
d, some of the following
test steps can be selected:
