b. Ensure the ON-OFF-POWER CHECK switch is in the OFF position.
c. Connect TI to appropriate power source.
8. Light Level Accuracy
NOTE
If the night vision device detector standard is exposed to
overload light conditions, several minutes are needed in low
light level conditions for the n ght vision device detector
i
standard to recover.
a. Performance Check
(1) Connect multimeter Input HI and LO to night vision device detector
standard BNC CONNECTOR (fig. 1).
(2) Install night vision device detector standard into TI RIGHT COLLIMATOR
(3) Turn night vision device detector standard power ON/OFF SWITCH (fig. 1) to
ON and allow night vision detector standard to warm up 5 minute.
NOTE
Multimeter must not be in autoranging.
(4) Set TI ON-OFF-POWER CHECK switch to ON and rotate FUNCTION
switch to LOW LIGHT LEVEL RESOLUTION.
(5) Pull TI ANVIS/NVG SELECTOR SWITCH (fig. 2) to NVG (up) position. If
multimeter does not indicate between 3.04 and 5.90 mV dc, perform b(1), (2), and (4)
below.
