Maintenance of Light Source Lamp
1
.
A high-performance xenon lamp is used as the light source lamp of the instrument. It is
mounted in a special lamp chamber as shown in Fig.1-3. The surface of the xenon lamp must be
kept clean.

.
When turning on/off the xenon lamp, should strictly follow the operating sequence.
Note: When starting up the instrument, please turn on the power source of xenon lamp first.
After the xenon lamp is lit, then turn on the power source of the main unit of the instrument. When
shutting down the instrument, please turn off the power source of the main unit of the instrument
first, and then turn off the power source of the xenon lamp.

.
When the voltage of power source is not stable and the capacity of power source is not
sufficient, or the xenon lamp closes to the limit of service life, lighting xenon lamp is often difficult.
Note: If the xenon lamp fails to be lit and a squeaking sound of high frequency or a cracking
sound of sparking is continuously produced, please turn off the power source of the xenon lamp
immediately. Several seconds later, then turn on the xenon lamp again.
4
.
The xenon lamp should avoid being turned on/off repeatedly under a high voltage.
Note: Because the life of the xenon lamp is closely related to the number of on-off of the lamp
power source, the unnecessary number of turning on/off the xenon lamp should be cut down as far
as possible.

.
After starting up the instrument, make sure that the heat dissipation fan of the instrument
runs normally, and be sure to keep the surface of heat dissipation opening at the top of the
instrument well ventilated.
4.2.2
Replacement of Light Source Lamp
A precise combination light source that has been corrected in advance in the factory is used in
the instrument. A professional man must be needed to replace a damage light source lamp. The
concrete method and the correcting procedures will be briefed through training.
