AUTION
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.
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)
EX) 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, adjust the B flange to
tilt it in λ form.
(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.
*1) Received light quantity might not increase to its maximum because of the influences from dust and
moisture in the stack unit, etc.
4.11.2 When an optional optical axis adjusting tool (laser
pointer) is not 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.
When the quantity of light is completely zero V, move the transmitter box from side to side and up and
down slowly to find the position where the received light quantity increases. If you cannot still confirm
the quantity of light, loosen the fixing bolts and nuts further, and check reaction of the digital voltmeter
while moving the box back and forth slowly. (*2)
(3) If you find reaction of light quantity increases, fasten the fixing bolts and nuts temporally, and perform
the operation in 2).
(4) If output is not as much as that measured at the time of calibration even if output is at its maximum on
the transmitter side, fix the box at the maximum output angle temporality and adjust the light axis,
moving the box on the receiver side similarly. When you can confirm the output at the time of adjusting
any of the boxes, do not loosen the fixing bolts and nuts too much, or the light axis can deflect further.
*2) Received light quantity might not increase to its maximum due to the influences from dust and moisture
in the stack unit, etc.

4.11 Adjustment of light quantity
• Do not look into the transmitter unit or direct the laser beam to the
eyes of people while the power is turned ON. Otherwise, the laser
beam may damage cornea of the eye.
• The laser beam is the invisible infrared light. Do not watch the laser
beam directly or scattering light.
• Do not watch the laser beam directly with the optical measuring
device. Otherwise, it may cause serious damage to your eyes.
