  • Page 5: Caution On Safety

    CAUTION ON SAFETY First of all, read this “Caution on safety” carefully, and then use the particle counter in the correct way. The following items are important for safe operation and must be fully observed. These safety precautions are ranked in 2 levels; “DANGER” and “CAUTION.” ANGER If operation is incorrect, a dangerous situation may occur, resulting in death or serious injury.
  • Page 6 Caution on Wiring AUTION (1) Be sure to connect a ground wire securely to the specified place by per- forming class D grounding work. Otherwise electric shock or malfunc- tion may result. (2) If the power supply voltage exceeds the rating, electric shock or damage to the instrument may result.
  • Page 7 AUTION  If the cause of any fault cannot be determined despite reference to the in- struction manual, be sure to contact your dealer or Fuji Electric’s techni- cian in charge of adjustment. If the instrument is disassembled carelessly, you may get an electric shock or injury.

  • Page 8: General

    1. GENERAL 1.1 General Cross-stack laser gas analyzer (ZSS) provides continuous measurement of HCl in-flue gas incineration, NH density of denitration equipment and heat treat furnace, and O , CO, and CO density for combustion control within a short response time. The cross-stack configuration eliminates the need for transfer of the preparation measurement gas to the analyzer for proper measurement.
