3. System description
3.1 Areas of application
UNIMET® 1100ST is used to test electrical safety. It has been designed for use in various
areas of application:
●
Testing of medical electrical equipment to DIN EN 60601-1 (VDE 750 Part 1):1996-03, ANSI/
AAMI ES1, UL 60601-1,
IEC 61010-1:2001-02
●
Periodic testing and testing prior to first use of medical electrical equipment or systems to DIN
VDE 0751-1:2001-10
●
Periodic testing of care beds and hospital beds
●
Single-phase electrical appliances:
“Repair, modification and inspection of electrical appliances” DIN VDE 0701-1:2000-09,
“Periodic inspections on electrical appliances” DIN VDE 0702:2004-06
●
As an option, the PE conductor resistance of the DUT is measured with a test current of 25 A.
●
With an appropriate adapter (DS601), also includes testing of three-phase electrical appliances
in safety classes I and II to VDE 0701-1 and VDE 0702-1.
3.2 Function
The test system performs measurement results which it evaluates immediately in order to
categorise the test as “passed” or “failed”. In addition to the electrical tests, the test sequence,
which follows classification, contains a visual inspection and a functional test. This test
procedure is saved in the type catalogue. The test can be carried out automatically or
manually for each DUT.
The test results can be displayed on-screen, saved or printed to an external printer. In the
event of unexpected results, the DUT can be inspected in more detail by carrying out a single
test. Once tested, devices can be saved to the device catalogue. The internal data memory
(FLASH disk) has space for 1000 entries in each of the type and device catalogues.
Tests can be transferred to a PC software program via an RS-232 interface (this is an option,
see “Standard version, options and accessories” on page 83). For periodic testing, this data,
which is stored in the PC software, is transferred back to the UNIMET® 1100ST. The RS-232
interface is also used for possible subsequent updates of the internal operating software on
the test system.
The test engineer name catalogue can be useful if more than one person is working with the
test system. Test engineers already registered on the system can simply be selected in the
test engineer names catalogue. There is no need to re-enter the test engineer’s name. Up to
9 test engineer names can be stored.
The large colour display is backlit. Graphics illustrate how to connect the DUT. Operation is
quick and easy via the keypad.
Optional accessories such as three-phase current adapters or portable printers extend the
scope of the test system (see page 83).
UNIMET® 1100ST has been designed solely for use in earthed systems. If the test
system is used other than for the intended purpose, i.e. in an IT system, the
measured values of any leakage currents will not be reproducible. The test result
cannot be used.
