Test Duration Counter
Indicates the duration of the test. This will count down to zero. When the counter reaches zero. The test counter
can be set to unlimited test duration (indicated by “UL” on the display). In this instance the counter will not
count down and requires user intervention to stop the test being carried out. Note that the test duration is
indication only.
Primary Display
Indicates test result and Equipment Class and Type. For some tests there is a minimum value displayed. If the
measurement is below this “mask” value then the mask value is displayed indicating that the measured value is
below the minimum indicated by the Analyser.
Secondary Display
Before a test, this display indicates test output e.g. voltage or current specified. During a test, this display may
show the current step in the automatic test sequence. After a test, this display compares the test result with
standard limits. During the leakage tests this displays the test being carried out in the test sequence. This is
indicated as a text
mnemonic comprising of the mains power condition and the Single Fault Condition (SFC) present during the
test.
For Patient Leakage and Patient Auxiliary tests two sets of sequences are carried out – one for ac only
measurements and the other for dc only measurements as required by EN60601.
Connecting the Analyser
The Analyser must be powered by a 230V/115V supply (dependent on unit supplied). Check the rating label on
the reverse of the unit for suitable mains voltage.
The supply to the Analyser must include an earth connection (e.g. via a 3 pin plug).
When switched on, the Analyser will carry out a short self-test procedure. Ensure the EUT is unconnected to the
Analyser during the power on self-tests. During this test, all display segments will be lit to allow verification of
correct operation of the display
Once the start-up procedure of the Analyser has been completed, the Analyser is ready for operation. The
display will depend on the rotary knob position.
