2 Safety Features and Precautions
This instrument fulfills the requirements of the applicable European and na-
tional EC guidelines. We confirm this with the CE marking. The relevant decla-
ration of conformity can be obtained from GMC-I Messtechnik GmbH.
The test instrument has been 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 Part 2 and 4 and DIN VDE 0104 (Feature F02 or
SECUTEST SIII+H )
Only when used for its intended purpose, the safety of the user, the test
instrument and the device under test (electrical equipment or electrical
medical devices) is assured.
Read the operating instructions carefully and completely before placing your test
instrument into service, and follow all instructions contained therein. Make sure
that the operating instructions are available to all users of the instrument.
Tests may only be performed by a qualified electrician or under the supervision of
a qualified electrician. The user must be instructed by a qualified electrician
concerning performance and evaluation 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 electrical systems with a
maximum of 230 V +10% which 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 interruptions in cables or plugs etc.
• When using a probe with coil cable (SK2W): Grip the test probe firmly,
for example after insertion into a jack socket. Tensioning at the coil
cord may otherwise cause the test probe to snap back resulting in
possible injury.
• Measurement of Insulation Resistance and Equivalent Leakage Current
This test is performed with a maximum voltage of 500 V, with a current
limit having been set (I < 3.5 mA). However, contacting the terminals
(3 or 2) causes an electric shock which, in turn, may result in accidents.
• Leakage Current Measurement
During leakage current measurement it is imperative to ensure that the de-
vice under test is operated at line voltage. Exposed conductive parts may
be charged with hazardous contact voltage during the test and may con-
sequently not be touched under any circumstances. (There is a power
shutdown as soon as the leakage current is higher than approx. 10 mA).
Attention!
!
The function test may only be performed after the DUT has
successfully passed the safety test!
Switching loads on and off
When switching the DUT on or off under load it is imperative that you ad-
here to the order indicated below. This helps to prevent excessive wear
and tear of the mains relays at the test instrument.
Before the measurement:
1) DUT: Switch the DUT off at the proprietary switch.
2) SECUTEST SIII+. . .:
Apply line voltage to the test socket .
3) DUT: Switch on the DUT at the proprietary switch.
After the measurement:
4) DUT: Switch the DUT off at the proprietary switch.
5) SECUTEST SIII+. . .:
Disconnect the test socket from the line .
The measuring and test instrument may not be used:
• If it demonstrates visible damage
• With damaged connector cables, measuring cables or patient ports
• If it no longer functions properly
• After extraordinary stresses due to transport
In such cases, the instrument must be removed from operation and
secured against unintentional use.
