Cautions For Use

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 checker 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.
