vPad-TI OPERATING MANUAL
2.4 Setup
To test a transport incubator according to the Standard, the Sensor System must be placed on
the mattress of the DUT with the Temperature Probe of the Hub in the center of the mattress,
and the Temperature Probes of the remaining 4 Temperature Pucks placed in the center of
each of the 4 quadrants of the mattress. The positioning frame is designed to assist in the
positioning of the Pucks and to hold them in place during a test.
Measure the mattress to determine its size. For instance, the AirShields C200 has a nominal
mattress size of 14 inches wide (36 cm) by 24 inches long (61 cm). Divide the mattress into 4
quadrants, each quadrant being 7 inches (18 cm) by 12 inches (30.5 cm). For this mattress, the
center of quadrant Q2 is 3.5 inches above the long axis and 7 inches from the cross axis, see
point
C2
, Figure 7 .
In setting up the positioning frame, the longitudinal (long) bar would be placed in the body of
the
HUB
, with the end having a small hole about 1" from the end sliding into the slot in the
HUB
, as indicated in Figure 8 . The ‘T- bracket’ is placed over the long bar and slid into the
position marked ‘6’ inches on the long bar. Similarly, the horizontal (cross) bar is slid into the
‘T- bracket’ and locked in place with the spring plunger. The smaller
Temperature Puck is
then slid into place to the position marked ‘3.5’ inches on the cross bar. If the positioning
frame is placed with the temperature probe of the
HUB in the center of the mattress at C1,
then the second temperature probe would be in the center of the mattress quadrant Q2 at
position C2 in the diagram. For mattresses of other sizes, the ‘small’
Pucks can be moved
along the bars as required to meet the dimensional requirements.
