TGH1256en/10.2005
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.

System description
12 TGH1256en/10.2005
3.3 Tests conforming to standards
UNIMET® 1100ST carries out measurements and tests based on the following standards (see
also the chapter entitled “Standards” on page 91):
●IEC 60601-1:1988
●DIN EN 60601-1:1996-03/VDE 0750 T1
●DIN VDE 0751 Part 1: 2001-10
●DIN VDE 0702:2004-06
●DIN VDE 0701-1:2000-09
●ANSI/AAMI ES1
●UL 60601-1
●IEC 61010-1
Tests to DIN EN 60601-1:1996-3 are carried out with the exception of the measurement of
PE impedance. PE impedance is measured in accordance with IEC 60601-1:1988.

4.1 Unpacking
Unpack all the parts supplied with the system. Do not use tools with sharp edges which
might damage the content of the package. Compare your order with our delivery note to
check that you have received all products in full. The article number printed on the
nameplates provides an easy means of uniquely identifying each device.
4.2 Commissioning
4.2.1 Setting up
Set the UNIMET® 1100ST down on an even surface with the accessories carrier face up. The
carrying handle also serves as a stand so that the UNIMET® 1100ST can be set down on an
even surface. Set up the handle as follows:
1. Pull both adjusting wheels (1) towards the handle (2) and keep hold of them.
2. Move the handle to the required position.
3. Let go of the two adjusting wheels (1). Move the handle a little until the adjusting wheels snap
into place.
4.2.2 Connection of keypad purchased as an optional accessory
1. Push the two grip ends (2) on the fixing axes inwards at the same time. Slot the keypad into
place and let go of the grip ends.
2. Connect the connecting cable for the external keypad to the keypad bush on Unimet.
Check all parts supplied for any evidence of damage in transit. Equipment
damaged in transit must not be used. If a device has sustained damage, please
contact BENTRON®. Details of who to contact are indicated on the delivery
documents.
When storing the devices in an environment where the temperature is wintry
and cold: Leave the devices to stand for 3 to 4 hours at room temperature before
connecting the power supply. When the devices are moved from a cold to a
warm environment, condensation will be evident on all parts. Putting damp
devices into operation risks damaging electrical components and there is a
danger of electric shock on contact.

4.2.3 Switching on
1. Connect the UNIMET® 1100ST to the supply voltage using the permanently attached power
supply cord.
2. Switch the device on using the power switch.
The test system requires approx. 20 seconds to start up and carry out self testing. The system
tests the system voltage and the voltage to PE. If the test system detects an IT system (e.g.
in the operating theatre) or an error, a message will appear.
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. Disconnect the test system and connect it to an earthed socket outlet.
UNIMET® 1100ST must always be connected to the supply voltage indicated on
the nameplate. Failure to observe this requirement may lead to the test system
and any DUT connected to it sustaining damage.
During testing, the UNIMET® 1100ST test socket is live. Do not touch the earthing
contacts on the socket.
Do not connect DUTs during the start-up phase. If the DUT is faulty, its enclosure
may be live. You risk dangerous electrical shocks by touching it.
The system voltage and automatic adaptation to this voltage are only checked
once UNIMET® 1100ST has started up. Changes to the system voltage made
during active measuring will not be detected. Therefore, before any changes are
made to the system voltage, UNIMET® 1100ST must be switched off via the
power switch. The new system voltage will be detected properly when Unimet is
restarted. If the system voltage is changed without UNIMET® 1100ST having
been switched off in advance, this may damage the current and voltage sources.
UNIMET® 1100ST is a test system for medical electrical and electrical equipment;
it is not an medical electrical device per se. Under no circumstances, therefore,
