7.3.4 Moisture interference compensation adjustment method
Proceed to an adjustment if excessively
(beyond
±
2% FS) affected by moisture
inteference.
After the end of optical balance adjustment, be
sure to carry out moisture inteference compen-
sation adjustment.
q
After warm-up, select the low range, allow
dry gas (N
2
, air) to flow at 0.5 L/min and
carry out zero calibration.
If the following operation is maladjusted, the measurement may adversely be affected. If you are
not trained for adjustment, do not carry out this operation but contact the distributor or our service-
man.
Caution
e
Carry out the adjustment in the procedure in
r
and subsequent.
•
When optical system 1 is adjusted. Get the values at
a
to
d
in 1-1 and 1-2 within
±
50
and as near 0 as possible.
•
When optical system 2 is adjusted. Get the values at
e
to
h
in 2-1 and 2-2 within
±
50
and as near 0 as possible.
o
After the optical balance adjustment, mount the top cover of the analyzer unit, then carry out
a moisture interference compensation adjustment, and perform zero and span calibrations.
* Before moving the beam adjustment plate, loosen the detector set bolts (just enough
to make the plate movable for snug adjustment).
