9.9. FREQUENTLY ASKED QUESTIONS (FAQs)
The following list of FAQs is from the Teledyne API’s Customer Service Department’s
most commonly asked questions relating to the T700 Dynamic Dilution Calibrator.
Question Answer
My ozone ACT =XXXX why? Look at the Photo Ref/Meas. These are most likely too low and need to
be adjusted up to 4500mV. Another possible cause would be no gas
flow to the photometer causing the O
3
reading to be out of range - low
When I generate ozone, it takes a
long time to settle out or it
fluctuates around the number until
finally stabilizing.
Perform an O
3
Gen Adjust (Section 8.2.5), and then an O
3
Gen
Calibration (Section 7.4). Re-run points.
Why does the ENTR button
sometimes disappear on the front
panel display?
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 3.3.1.7, 5, and 9.4.14
When should I change the
sintered filter(s) in the calibrator’s
critical flow orifice(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,
contact Customer Service.
How often should I rebuild the
photometer pump on my
calibrator?
It does not require rebuilding; the entire pump should be replaced every
two years.
How long do the UV lamps of the
optional O
3
generator and
photometer last?
The typical lifetime is about 2-3 years.
