8.3 TURNING WHITE/UV FLASHLIGHT
ON/OFF
When pressing the flashlight button adjacent to the power on/off button, the lights on the
back of the VJ-4 video borescope switch between a white light flashlight, a UV flashlight
and turning off the flashlight.
NOTE:
The UV has a center wavelength of 365nm and
luminous power of 50mW.
8.4 INSERTING THE INSERTION TUBE
INTO MACHINERY OR EQUIPMENT
Inserting the insertion tube:
Make sure the insertion tube and bending section are straight before starting the
inspection.
DO NOT attempt to articulate the bending section with the joystick while
the insertion tube is coiled, as this will result in breakage of the articula-
tion control wires.
• After the insertion tube enters the inspection port, adjust the brightness as necessary
and use the LCD monitor to see the internal view.
• Manipulate the joystick as needed in order to steer the insertion tube and camera/LED
module to the inspection target.
