The TS-4348/UV Test Set can be used by the operator to check
the resolution of a goggles at any time.

Test Set.
NOTE
Verify the resolution of the goggles using the TS-4348/UV Test
Set at every opportunity. The resolution cannot be accurately
measured without the test set.
The following procedures are designed to check the performance

yourself with its operation and the warnings and cautions associ-
ated with that test equipment.
NOTE
• The resolution test must be performed in a darkened area.
Your eyes must be dark-adapted to perform this test. Review
the following test procedure before entering the dark area.
• Expect cosmetic blemishes, such as chicken wire, black
spots, and fixed-pattern noise, to stand out while viewing
through the TS-4348/UV Test Set when it is on the high light
level. This is acceptable.
• The rejection of any NVG for cosmetic defects must be based
on an outdoor evaluation and not the TS-4348/UV Test Set.
b. Low Light and High Light Resolution Test Procedure

according to the following steps.
