  • Page 5: For Safety

    FOR SAFETY In this manual, important safety instructions are specially marked as shown below. To prevent the risk of death or injury to persons and severe damage to the unit or peripheral equipment, make sure that all instructions are fully understood and observed.

  • Page 6: Laser Precautions

    WARNING This particle counter uses laser sources. This unit is designated as a class 1 laser product according to IEC 60825-1:2014. The internal particle detector mechanism uses lasers, but they are fully shielded so that the beam cannot exit from the enclosure. The identification label shown below is affixed to the top of the unit.

  • Page 7: Measurement Limitations

    “Specifications”. - With compressed or depressed gases. - In environmental conditions which exceed the temperature and humidity limits listed in the section “Specifications”. When intending to use the KC-31/KC-32 to measure other gases besides air, please consult the supplier.
  • Page 8 Caution Precautions • Operate the unit only as described in this manual. • Do not exert strong force to the inlet. Be especially careful when con- necting or disconnecting the supplied isokinetic probe. • When connecting the supplied isokinetic probe, make the connection firmly by hand.
  • Page 9 • If the unit is used in a method not specified by the manufacturer, the protection provided to the unit may be impaired. • Do not pass reactive gases through the unit, to prevent the risk of an internal explosion. •...
  • Page 10 • Insert the plug of the cable from the AC adapter firmly into the power connector on the unit. • Do not use the AC adapter for any other product besides the KC-31/KC-32. • Do not use the AC adapter outdoors or in an environment with high tem- perature and humidity.

  • Page 17: Outline

    The unit can display a particle count for six size ranges: ≥0.3 µm, ≥0.5 µm, ≥1.0 µm, ≥2.0 µm, ≥5.0 µm, and ≥10.0 µm. The flow rate is 28.3 L/min for the KC-31 and 50 L/min for the KC-32, ad- justed by an automatic flow rate control function.

  • Page 18: Light Source Service Life

    Outline While the power is off, the measurement parameter settings is memorized automatically. Measurement to be continued with the same settings the next time power is on. An alarm level can be set to sound a warning buzzer when the particle count exceeds a preset threshold.

  • Page 19: Particle Size Detection

    The unit is intended for use with connected tubes under reduced pressure (KC-31 to about −1 kPa at the lowest, KC-32 to about −2 kPa at the lowest). The maximum tube length for automatic flow control is 10 meters. Collection efficiency especially for large particles is not assured in this condition.

  • Page 196 Ethernet connection Command message The computer specifies an action of the KC-31/KC-32 with a command message. Command message consists of the message header “C/” and one to four commands, such as “C/L=1”. In the following explanation, only the parts after the “C/” message header are explained.
  • Page 197 Identify command “I=n” This command allows checking whether the KC-31/KC-32 can be con- trolled by the computer. Before starting to control a KC-31/KC-32, the computer should send this command. Checking the <identify flag> of the <status response> returned by the KC-31/KC-32 then allows the computer to determine if power was turned off or if a reset was performed.

    Maintenance Internal contamination of sensor When the internal sensor has become contaminated, performance will decrease and servicing may become necessary. It is advisable to avoid measurement of air containing mist, moisture droplets, coarse particles, fibers and similar, or a very high number of particles. Also take care to always store the unit with the inlet cap in place.
