8.8. FAQ’S
The following list is from the TAPI Technical Support Department of the 10 most
commonly asked questions relating to the Model T703 Photometric Calibrator.
Look at the Photo Ref/Meas readings from the photometer UV lamp detector
are most likely too low and need to be adjusted. See Section 7.5
When I generate ozone, it
takes a long time to settle out
or it fluctuates around the
target concentration until finally
stabilizing.
Perform an O
3
Gen Calibration. See Section 6.2.
Why does the ENTR key
sometimes disappear on the
front panel display?
Sometimes the ENTR key will disappear if you select a setting that is invalid or
out of the allowable range for that parameter, such as trying to set the 24-hour
clock to 25:00:00. Once you adjust the setting to an allowable value, the ENTR
button will re-appear.
How do I make the RS-232
Interface Work?
See Sections 3.2.6.3 and 5.1
When should I change the
sintered filter(s) in the
calibrators flow control(s) and
how do I change them?
The sintered filters do not require regular replacement. Should one require
replacement as part of a troubleshooting or repair exercise, see Section 8.7.1.
How often should I rebuild the
photometer pump on my
calibrator?
The photometer pump has been designed for longer service life than standard
diaphragm pumps. When the pump wears out, the entire pump must be
replaced.
How long do the UV lamps of
the O
3
generator and
photometer last?
The typical lifetime is about 2-3 years.
