3
Points for Attention to Operation
1.
The Spectro 96 Fluorospectrophotometer is suitably used
in a laboratory room to perform
analytical measurements. If the instrument needs to be used at a worksite, the working
environment of the worksite should accord with the demands of the laboratory environment
basically.
2. If the user needs to move the instrument to other working site for analytical measurements,
please use original packing materials on moving.
3. Be sure to turn on
⁄
off the power of the instrument according to the operating procedure.
When starting up the instrument, please turn on the power source of the xenon lamp first.
Then turn on the power source of the spectrophotometer main unit after the xenon lamp is
lit. When shutting down the instrument, please turn off the power source of the
spectrophotometer first and then the power source of the xenon lamp. Otherwise, the
instrument may not work normally. After the xenon lamp is lit, it is necessary to wait for 30
minutes over till the lamplight becomes stable. After the power source of the xenon lamp is
turned off, please wait for 60 seconds, and then turn on the lamp if the lamp needs to be
used again.
4. When the power source of the xenon lamp is turned on but the lamp fails to be lit and a
squeaking sound of high frequency or a cracking sound of sparking is produced
continuously, please turn off the power source of xenon lamp immediately and wait for
several seconds, then turn on the lamp again. Because the life of the xenon lamp is closely
related to the number of on-off of the lamp power source, the lamp should avoid being
turned on/off repeatedly under a high voltage and the unnecessary number of on/off of the
xenon lamp power source should be cut down as far as possible.
5.
When the instrument is working, the surface temperature of the heat dissipation opening at
the top of the left back side of the instrument (xenon lamp position) becomes very high. Be
sure not to touch the surface of the heat dissipation opening with hands in order not to be
burnt. The air around the heat dissipation opening should be kept circulating.
6.
After each startup of the instrument, please first confirm that the heat dissipation fan at the
side of the instrument runs normally in order to ensure normal work of the instrument. If
the user finds anything wrong with the heat dissipation fan, the instrument should be closed
down for an overhaul.
7.
In order to protect the photomultiplier when PMT level is higher (>6), do not let high light
pass into the sample compartment. When a sample of unknown concentration is measured,
PMT level should be set from low grade to high grade (1-17) gradually.
8.
After PMT level is adjusted, the original set for zero-point of fluorescence should be
checked and note that zero-point adjustment may be needed again.
9.
When and only when a computer error is due to the operator¹s false operation or other
interferences, the power switch of the spectrophotometer main unit should be turned off
immediately. When the software cannot be operated, please use task manager to end the
“f96pc.exe” process, then restart the software and the instrument.
10.
Within the monochromator the tightened screws must not be loosened. The optical devices
and the working environment of the instrument should be kept clean.
11.
When opening the cover to inspect the instrument, be sure to turn off the power source.
Particularly after the upper cover of the instrument is removed, as there are electrical
appliance parts with high voltage located at the left back of the instrument base, be sure not
to contact these parts while the power source is still turned on.
