The IR source control system has been designed to operate the wire wound
resistor IR source conservatively in order to increase its life. Nevertheless,
the IR source does have a finite life. Since the IR source is relatively
inexpensive and easily replaced, it is recommended that the IR source be
replaced after one year of continuous use. This will prevent loss of data due
to IR source failure. If an IR source is to be replaced on an as needed basis,
it should be replaced when:
●
There is no light output
●
After cleaning the optics, the IR light intensities remain below 100,000
Hz
Use the following procedure to replace the IR source from DMC.
1.
Turn the instrument OFF, unplug the power cord, and remove the
cover.
2.
Disconnect IR source cable as shown.
Figure 7–48.
