4.0 OPTI-LITE OPERATIONS
4.1 Operation
A. Once the Light Guide has been inserted and Illuminator box is plugged in,
turn the ON/Off Intensity Control Knob to power on.
B. NOTICE: When switching on a cold Illuminator Box, leave the intensity control
at low intensity for a minimum of ten seconds before increasing to full
intensity. This will allow the Lamp to warm-up, helping to extend the Lamp
life. After using the OPTI-LITE, return Intensity Control Knob to low and allow
a cool down time of one to two minutes before turning the unit off.
C. After the above steps have been performed, the Light Guide can be inserted
into the cylinder neck to proceed with inspections. Always avoid looking
directly into the Light Guide once the unit has been turned on.
4.2 Intensity
A. Although halogen lamps are an inexpensive and effective light source, they
can degrade by an average of 15% over the lifetime of the lamp. Furthermore,
new lamps of the same brand and model number may vary +/- 20% in
maximum intensity, depending on the batch.
B. Under normal conditions, lamp manufacturers recommend halogen lamps be
operated above 80% of their rated intensity for optimum and stable lamp
performance.
