vPad-TI OPERATING MANUAL
These two values may be input multiple times after STC has been reached, up to the end of the test.
If they have been enabled and no values have been input before the end of the test time, these dialog
boxes will appear at the end of the test automatically. Each time a value is entered, a comment is
entered in the Raw Data file. The Pass/Fail determination will be based on the last entered value.
At the end of the test, the Results summary will be displayed, Figure 78. In addition to the
Average Incubator Temperature (AIT)
and the length of time that
STC
was true, vPad-TI
will also report other values required by the Standard. The terms
AT2
-
AT5
refer to the
Average
Temperature at each of the locations in the centers of the four quadrants of the mattress. These
averages are calculated in a similar manner to the
AIT
value, from the temperatures measured at
locations T2 - T5. These averages must not differ from the
AIT
by more than 1.5 °C when the
mattress is horizontal, or by more than 2 °C if the mattress is tilted. The Standard requires that
difference between the
AIT
and the
CT
be not more than ± 1.5 °C.
When OK is pressed on the Result screen, you are returned to the temperature graph screen and the
graph shown is what will be saved to a JPG file if the option to
Save Picture to JPG Afer Test
has been enabled in the System Settings. The Result will include a filename of the JPG image of
the temperature versus time graph. This filename will be included in the test report for reference.
5.9 Air Temperature Control Test - Low
The
Air Temperature Control - Low
is identical in format to the
Air Temperature Control
- High
test, with the exception that it is done at a temperature which is less than that set for the
High test. Although the Standard does not dictate a temperature, it does recommend a temperature
of 32 °C. vPad-TI will default to the recommended value when setting up the Low temperature
value, but other temperatures may be selected. In the event that this test follows a test at a higher
temperature, the instructions (see Figure 79) suggest that the doors or portals of the incubator be
opened to allow the temperature to fall to at least 33 °C to reduce the time required for the test.
