Confirm that the LED light panel lights are on and operating properly.
•
Confirm the presence of both blue and yellow LEDs lighted in rows.
•
Examine panel geometry for uniform light spacing and unlighted LEDs.
Note:
The UUT can conform to specifications with some LEDs not lighted. However, if a large
number of LEDs are not lighted it may prevent the UUT from meeting minimum values required
during testing. If enough LEDs are missing the LED intensity adjustment may need to be
adjusted higher than necessary, which would reduce panel life.
•
Press the target light rocker switch and verify that a diamond shaped group of RED LEDs is
lighted in the center of the LED light panel. The light must extinguish when the rocker switch is
released.
9
Verify that the Illuminated On/standby switch lights up.
10
Verify the timer is operating. The decimal point should be flashing if the device is on and not flashing
when the device is off. Turn off the UUT by turning off the Illuminated On/standby switch.
11
Check the light intensity. (See below.)
2.3.2 Checking the light intensity
Important!
Initial intensity measurements were factory calibrated with the neoBLUE
®
Radiometer and
were based on the patient being 12 inches (30.5 cm) from the light panel diffuser of the UUT. The
light output can also be adjusted using the two potentiometers on the device (Section 2.4 Adjusting
Light Intensity) to accommodate different distances. Adjusting the UUT light intensity higher will
decrease expected LED light panel life.
Because your facility may use a different radiometer to measure the light intensity output, it is necessary
to understand how your reading may differ from the neoBLUE Radiometer reading. Please refer to the
Conversion Chart in chapter 6 for information on other meters.
