(3) Carry out the adjustment in the procedure in (4) and subsequent.

● Adjust on the primary side of the optical system so that the values for a to d in 1-1 and 1-2

become as close to 0 as possible within ±100 range.

● Adjust on the secondary side of the optical system so that the values for e to h in 2-1 and 2-2

become as close to 0 as possible within ±100 range.

(4) Operate the optical zero adjustment

a (or e ).

(5) Move the dimmer plate side view to

change the value displayed at b (or

(6) Move the dimmer plate sidewise to

change the value displayed at c (or

h ).

(8) Repeat the procedures in (4) to (7) to

make all the displayed values come

close to 0 as possible within ±100

range.

* Adjust the dimmer plate which is the nearest

to the zero adjustment knob first, and sequentially.

(9) 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 dimmer plate, loosen the detector set bolts (just enough to make the plate movable for snug

adjustment).

7.3.4 Moisture interference compensation adjustment method

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 serviceman.

Proceed to an adjustment if excessively (beyond ± 2%

FS) affected by moisture interference.
After the end of optical balance adjustment, be sure to

carry out moisture interference compensation adjustment.
(1) After warm-up, select the low range, allow dry gas

, air) to flow at 0.5 L/min and carry out zero

calibration.
