Testing and measuring

The test sequence (automatic, semi-automatic, manual) can be modified subsequently. You
must also complete the remaining settings, which are valid for all devices of this type (start-
up, warning notice, test costs).
5.2.7.3 Configuring the warm-up and cooling-down phases
Once they have been switched on, an increasing number of DUTs need to complete a self
test and warm-up phase or a cooling-down phase prior to shutting down. Examples include
computers, processor-controlled devices and laser equipment.
For these devices, the UNIMET® 1100ST may only commence measurements once the DUT
has warmed up or “booted”. Otherwise, there is a risk that the parts of the device to be tested
will only have switched on partially or not at all, and therefore will not be tested.
Once measurements are complete, the UNIMET® 1100ST may only shut down the DUT once
it has booted down or cooled down. Otherwise, on laser equipment, there is the risk
overheating or, on a computer, of sectors of the hard disk becoming unusable.
The features of the “warm-up and cooling-down phase” on the UNIMET® 1100ST are as follows:
This function is available for the following tests:
●
IEC 60601-1:1988+A1:1991 + A2:1995
●
DIN VDE 0751-1:2001-10
●
DIN VDE 0701-1:2000-09
●
DIN VDE 0702:2004-06
It can only be configured for complete test sequences from the:
●
classification
●
type catalogue and
●
device catalogue
The warm-up and cooling-down phase is not active:
●
during single testing,
●
during test sequences compiled in the UNIMET® 1100ST test step editor,
●
during test sequences compiled from single tests in a computer program.
