3. System description
3.1 Function
The UNIMET® 300ST is used to test electrical safety. It has been designed for following areas of use:

Hospital and care beds

"Prüfung nach Instandsetzung, Änderung elektrischer Geräte - Wiederholungsprüfung elek-
trischer Geräte" (Inspection after repair, modification of electrical appliances - Periodic inspec-
tion on electrical appliances) DIN VDE 0701-0702 (VDE 0701-0702):2008-06

with appropriate adapter
*
also protection class I and II three-phase electrical equipment
according to DIN VDE 0701-0702 and DIN EN 62353
* Use the DS32DCT three-phase current adapter to test devices
not
being in operation.
Use the DS32A three-phase current adapter to test devices during operation.
The test system supplies measurement results which it evaluates immediately in order to classify the
test as "passed" or "failed". The test sequence which follows classification contains a visual inspection
and a functional test in addition to the electrical tests. The test sequence can be carried out automat-
ically or manually depending on the device under test.
The test results can be displayed on the screen, saved or printed out using an external printer. In the
event of unexpected results, the DUT can be inspected in more detail by carrying out a single test.
The device catalogue provides memory space for the test results from up to 600 tested beds or de-
vices.
Tests can be transferred to a PC software program via the RS-232 interface. This software is included
with the UNIMET
®
300ST. For recurrent tests, the data stored in the PC software are transferred back
to the UNIMET® 300ST. The RS-232 interface is also used for any subsequent updates of the internal
operating software on the test system.
The test engineer catalogue can be beneficial if more than one person is working with the test sys-
tem. Test engineers already registered on the system are simply selected from this folder. There is no
need to re-enter the name of the test engineer. The names of up to ten test engineers can be stored.
The LC display is backlit. For entering data, a standard keyboard or barcode reader can be connected
to the PS/2 interface.
UNIMET® 300ST has been designed solely for use with earthed systems. If the test
system is used other than as intended, i.e. on an IT system, the measured values
of any leakage currents will not be reproducible.
The test result cannot be used.
Alternative measurements of leakage currents, however, carried out with the
UNIMET® 300ST in IT systems will deliver correct test results.
