2 Safety Features and Precautions
SECUTEST BASE(10), SECUTEST PRO and SECULIFE ST BASE(25) test
instruments fulfill the requirements of the applicable EU guidelines
and national regulations. We confirm this with the CE mark. The
relevant declaration of conformity can be obtained from GMC-I
Messt
echnik GmbH.
The test instruments are manufactured and tested in accordance
with the following safety regulations: IEC 61 010-1 / DIN EN
61
010-1 / VDE 0411-1,
DIN EN 61557-16/VDE 0413-16.
The safety of the user, the test instrument and the device under
test (DUT) is only assured when the instrument is used for its
intended purpose.
Read the operating instructions carefully and completely before placing your
test instrument into service. Follow all instructions contained therein. Make
sure that the operating instructions are available to all users of the instru-
ment.
Tests may only be performed by a qualified electrician, or under the
supervision and direction of a qualified electrician. The user must be
instructed by a qualified electrician concerning performance and evalua-
tion of the test.
Note
Manufacturers and importers of electrical medical devices must
provide documentation for the performance of maintenance by
trained personnel.
Observe the following safety precautions:
• The instrument may only be connected to TN, TT or IT electrical
systems with a maximum of 240 V which comply with applicable
s
afety regulations (e.g. IEC 60346, VDE 0100) and are protected
with a fuse or circuit breaker with a maximum rating of 16 A.
• Measurements within electrical systems are prohibited.
• Be prepared for the occurrence of unexpected voltages at devices
under test (for example, capacitors can be dangerously charged).
• Make certain that the measurement cables are in flawless
condition, e.g. no damage to insulation, no cracks in cables or
plugs etc.
• When using a test probe with coil cord (SK2W): 
Grip the tip of the test probe firmly, for example during inser-
tion into a jack socket. Tensioning at the coil cord may other-
wise cause the test probe to snap back
resulting in possible
injury.
•
Measurement of insulation resistance and equivalent leakage current 
(alternative leakage current measuring method) 
Testing is conducted with up to 500 V. Current limiting is uti-
lized (I < 3.5 mA), but if terminals L or N at the t
est socket or
at the test probe are touched, electrical shock may occur
which could result in consequential accidents.
• L
eakage current measurement while connected to line voltage 
It is absolutely essential to assur
e that the device under test is
operated with line voltage during performance of the leakage
current measurement. Exposed conductive parts may con-
duct dangerous touch voltage during t
esting, and may not
under any circumstances be touched.
(Mains power is discon-
nected if leakage current exceeds approx. 10 mA.)
Attention!
!
The function test may only be performed after the DUT
has successfully passed the safety test!
• Fuse replacement 
The fuses may only be replaced whe
n the instrument is volt-
age-free, i.e. the instrument must
be disconnected from
mains supply power and may not be connected to a measur-
ing circuit. The fuse type must comply with the specifications
in the technical data or the labeling on the instrument.
