vPad-TI OPERATING MANUAL
Humidity Checks
The humidity measurement capabilities of the Baby Incubator may be checked by enabling this test.
The
Incubator Humidity (IH)
is tested according to the Standard, clause 201.12.1.1079. The
Standard requires the indicated value of relative humidity (RH), to have an accuracy of 15% of the
actual measured value. vPad-TI will measure the humidity level (normally at the center of the
mattress), and allow the manual entry of the incubator’s displayed value after
STC
is reached.
vPad-TI will compare the manually entered value of humidity to the value measured by the vPad-TI
Humidity Sensor . The control temperature should be set at a value between 32 °C and 36 °C for
this test.
Temperature Checks
The Standard requires the incubator to have an independent, non-mercury thermometer which can
be read without opening the incubator. Enabling the Temperature Check option will allow entry of
the value indicated on the independent thermometer after
STC
is reached. The Standard requires
the
Independent Incubator Temperature (IIT)
clause 201.12.1.105 to be no more than 1 °C
different than the measured IT . The sensor should be checked at 32 °C and 36 °C.
Alarm Sound Level - Inside
The Standard requires the alarm sound levels to be tested inside and outside of the incubator to
ensure they are not so loud as to injure the infant, and loud enough to be heard by the operator. For
the test inside the incubator, the requirements are defined in clause 201.9.6.2.1.103. The sound
pressure level (A weighted) is measured at a position of 10-15 cm above the center of the mattress,
with the incubator operating at 36 °C. The sound level during an alarm must not exceed 80 dBA.
This test is best combined with the Air Temperature Control Low test.
Alarm Sound Level - Outside
The Standard requires the alarm sound levels to be tested inside and outside of the incubator to
ensure they are not so loud as to injure the infant, and loud enough to be heard by the operator. For
the test outside the incubator, the requirements are defined in clause 201.9.6.2.1.102. The sound
pressure level (A weighted) is measured at a position 3 meters perpendicular to the front of the
incubator, 1.5 meters above the floor. The test shall be performed with the incubator operating at
36 °C, and at maximum humidity. The sound level during an alarm must be at least 65dBA. This
test is best combined with the Air Temperature Control Low test
