4.3 Mounting range of companion flange (in factory range)
Mount the companion flange so that it satisfies the conditions of the following figure (Fig. 4
2). If the con-
ditions below are not satisfied, light cannot be received even if the light axis adjustment is performed by the
angle adjustment unit. In such a case, mount the companion flange again.
When
θ
(angle determined by laser light source and flange diameter) is bigger than 5°, mount the companion
flange within the
γ
angle (
≈
5°) inside the circle with A radius.
When the distance between laser light source and stack is long, or
θ
angle is less than 5° because flange di-
ameter is small, both A radius and
γ
angle will become smaller, and the mounting conditions will be strict.

4.4 Preparation article for adjustment test
It is recommended to prepare the following fixtures for the adjustment test before installation.
Fixtures list
(1) Cable between receiver unit and control unit (for calibration)
(2) Cable between receiver unit and transmitter unit (for calibration)
(3) Calibration gas cell
(4) Power supply drum (or power supply extension cable)
(5) Digital
multimeter
(6) BNC for light axis adjustment (ZZP
*
ZSSTK7P2524C1)
(7) Flow meter (about 2L/min)
(8) N
2
Gas cylinder
(9) Gas cylinder corresponding to the span (80 to 100% of span)
(10) Regulator (for gas cylinder) (For HCL/NH
3
meter, prepare a SUS regulator. If using a brass regulator,
use it only once and then discard it. A brass regulator may get rusty inside, and the rust absorbs gas
to disturb accurate measurement.)
(11) Teflon tube (
10/8) a few meters
(12) Rc1/4 ×
10/8 joint, two or more
(13) Tools (2 monkeys, measure, cutter, Phillips screwdriver, flat-blade driver, hexagonal wrench, tube
cutter)
(14) Plastic sheet
