Convenient for beam alignment
Since the optical axis of a thru-beam type photoelectric sensor can be checked,
beam alignment is easy.
Suitable for all sensors
This product can be used with infrared,
as well as, red beam type of thru-beam
type photoelectric sensors.
Compact and light weight
Since the sensor checker has a
compact size (W100

), it can
be conveniently carried to the place of
use.
(Power supply: 9 V dry cell)
Light and sound indicate optimum position
When the emitter of the thru-beam
type photoelectric sensor and
CHX-SC2 face each other along a
straight line and their optical axes
match, the number of LEDs which light
up in the level indicator, as well as, the
sound tone increases.
Since the sound tone can also be
heard with an earphone, the sensor
checker can be used in a noisy place.

Description
Function
Method of use
1
Set the power supply switch ON. At this time, the buzzer
may sound even if light is not incident. However, if the
sensitivity adjuster has been set to min., the buzzer will not
sound.
2
Set the sensitivity adjuster to max.
3
Make the emitter and CHX-SC2 face each other along a
straight line.
4
When light from the emitter is incident, the level indicator
LEDs light up and the sound tone increase. The buzzer starts
sounding when 3 or 4 LEDs of the level indicator light up.
5
By turning the sensitivity adjuster, adjust the sensitivity
such that about 3 LEDs of the level indicator light up.
6
Move CHX-SC2 up, down, right and left to determine the
optimum position where the maximum No. of LEDs of
the level indicator light up and the buzzer sound tone is
the highest.
At this time, if the sensitivity has been set too high,
although a part of the level indicator may light up even in
the beam interrupted condition, it does not indicate any
abnormality.
7
If the sensor checker is being used in a noisy
environment and it is difficult to hear the buzzer, use by
connecting earphones. In this case, the buzzer does not
sound.
Others This product is suitable for use with infrared beam and red
beam type of thru-beam type photoelectric sensors. Use 6F22 (S-006P) type 9 V dry cell (1 pc.) for the power
supply. Since the 9 V dry cell is not supplied as accessory,
please arrange it separately. Make sure that the power supply switch of CHX-SC2 is
OFF when the dry cell is installed or replaced. Switch off the power supply when not using the sensor
checker. Further, if the sensor checker is not used for a
long time, remove the dry cell from the sensor checker
and keep it separately. Take care that the sensor is not directly exposed to
fluorescent light from a rapid-starter lamp or a high
frequency lighting device, as it may affect the beam
alignment.
