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,
must patients be connected to UNIMET® 1100ST. Similarly, patients must not be
connected to medical electrical devices connected in turn to UNIMET® 1100ST.
Failure to observe these instructions can lead to hazardous electrical currents.
