AUTOMATICALLY by using the TS-23/A Strobe Light Tester. If the test is to
be conducted MANUALLY, follow the test procedures as outlined in paragraph
(1) above, except limit the test duration to two (2) minutes. Again, a flash rate of
50 ± 10 flashes per minute is the acceptable test rate. If using the TS23/A Strobe
Light Tester for this inspection, the light can be tested in the TS-23/A with the IR
filter in place, by placing the lens/filter over the inspection window on the TS-23
face label and then pressing the trap door down to turn the TS-23 "ON", or by
removing the flashguard shield and inserting it into the tester. This is
accomplished by separating the main body of the light from its flashguard shield.
This separation is performed by holding the main body of the light with one hand
while grasping the flashguard shield with the other and pulling in opposite
directions. After separation, insert the top of the light into the trap door on the top
of the TS-23/A, insuring that the xenon lamp is fully inserted into the tester. Turn
the light switch ON and note the numerical reading recorded on the digital
readout of the tester. An acceptable reading between 100-150 is required and
equates to a flash rate of 50 ± 10 flashes per minute. If a reading of less than 100
is noted, replace both batteries and, if necessary, clean the battery contacts in the
light, then repeat the test. Should any light continue to fail this test, discard the
light in accordance with local procedures. Upon completion of this test, the light
is to be reassembled by inserting the top of the light (lamp) into the bottom of the
flashguard and pushing upward until it stops.
Note: Standard ambient temperature for performing flash rate test is 70°
Fahrenheit. Lower temperature may perhaps result in somewhat lower flash
rates.
c. BA-3058/U battery ("AA" Alkaline) or equivalent. Currently only a commercial
test fixture exists to test the BA-3058 Radio Shack part number 910-2135 Type
22-096 or equivalent. Therefore, batteries surpassing their
lifecycle/manufacturing duration's or batteries that are found to be defective will
be discarded in accordance with local disposition instructions/guidelines.
