2 Safety Features and Precautions
SECUTEST BASE(10) and SECUTEST PRO test instruments fulfill all
requirements of applicable European and national EC directives.
We confirm this with the CE mark. The relevant declaration of
conformity can be obtained from GMC-I Messtechnik GmbH.
The test instruments are manufactured and tested in accordance
with the following safety regulations: IEC 61010-1 / DIN EN
61010-1 / VDE 0411-1, DIN VDE 0404,
DIN VDE 0413 parts 2 and
4, DIN EN 61557-16/VDE 0413-16 (draft).
The safety of the user, the test instrument and the device under
test (electrical equipment or electrical medical device) 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.
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
safety 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 test socket are
touched, electrical shock may occur which could result in
consequential accidents.
• Leakage current measurement while connected to line voltage
It is absolutely essential to assure 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 testing, and may not
under any circumstances be touched.
(Mains power is discon-
nected if leakage current exceeds approx. 10 mA.)
The function test may only be performed after the DUT
has successfully passed the safety test!
• Fuse replacement
The fuses may only be replaced when 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.
Opening the Instrument / Repairs
The instrument may only be opened by authorized, trained per-
sonnel in order to ensure flawless operation and to assure that the
guarantee is not rendered null and void.
Even original replacement parts may only be installed by autho-
rized, trained personnel.
If it can be ascertained that the instrument has been opened by
unauthorized personnel, no guarantee claims can be honored by
the manufacturer with regard to personal safety, measuring accu-
racy, compliance with applicable safety measures or any conse-
quential damages.
If the guarantee seal is damaged or removed, all guarantee claims
are rendered null and void.
Before opening the housing, pull the mains plug out of
the outlet and wait for at least 5 minutes.
Switching Power Consumers
Be absolutely sure to adhere to the sequence specified below
when switching the live device under test. This prevents excessive
wear of the mains relays at the test instrument.
Before measurement:
1)
DUT
:
Turn the DUT off via its own switch.
2) Tester:
Switch line voltage to the test socket.
3)
DUT
:
Turn the DUT on via its own switch.
After measurement:
4)
DUT
:
Turn the DUT off via its own switch.
5) Tester:
Deactivate line voltage to the test socket.
The test instrument may not be used:
• If external damage is apparent,
for example if parts which conduct dangerous touch voltage
are freely accessible,
if the display is broken or defective (in which case dangerous
voltage or mains connection errors might no longer be indi-
cated)
• If the seal or sealing lacquer has been removed as the result
of repairs or manipulation carried out by an unauthorized/non-
certified service provider.
• With damaged connection and/or measurement cables and patient
ports, e.g. interrupted insulation or kinked cable
•If the instrument no longer functions flawlessly
• After extraordinary stressing due to transport
In such cases, the instrument must be removed from operation
and secured against unintentional use.
Meanings of Symbols on the Instrument
The symbols on the instrument have the following meanings:
Warning regarding dangerous electrical voltage
Warning concerning a point of danger
(attention: observe documentation!)
CE conformity marking
This device may not be disposed of with the trash.
