4.11 Adjustment of light quantity
Note that if you loosen more than one fixing bolts or anchor nuts at a time to adjust, it takes a lot of time to
resetting.
4.11.1 When an optional optical axis adjusting tool (laser
pointer) is used for angle adjustment
(1) Connect the digital voltmeter using the BNC receptor cable, referring to “4.6 Checking received light
quantity”.
(2) The reference light quantity is based on the output in zero calibration or voltage value of light quantity
which is described in a nameplate.
If the output is not as much as that measured at the time of calibration before the adjustment, find a po-
sition where the received light quantity increases, moving the transmitter box from side to side and up
and down slowly. (*1)(*2)(*3)
(3) When the output not as much as that measured at the time of calibration, even if it is at its maximum on
the transmitter side, fix the box at the maximum output angle temporarily and adjust the light axis,
moving the receiver box similarly.
Do not loosen more than one bolt or loosen fixing bolt and nut widely in both cases of adjustment.
Light axis may deflect again.
(4) Move the transmitter unit and the receiver unit from side to side and up and down to adjust until the
voltage value of light quantity of digital multimeter becomes smaller in all directions.
(5) Retighten all volts to fix them (If the light quantity decreases at retightening, adjust again).
*1) Received light quantity might not increase to its maximum that was confirmed by “4.6 Checking re-
ceived light quantity” due to the influences from dust and moisture in the stack unit, etc.
*2) When using the high-speed/AGC version (i.e. the 22th digit of code symbols is "H"), adjust the light axis
under the status that the level of AGC is "01" (refer to "5.3 Outline of screen ").
*3) When using CO + O

analyzer, check the received light quantities at two points, and then adjust them to
be maximum.
e.g.) In the case that the quantity of light increases when the
whole transmitter box is moved upward.

As the quantity of light increases when the light axis
turns downward, loosen the fixing bolt in reference to
“4.7.2 How to operate the angle adjustment unit 2”.
