• As performance may deteriorate through the adhesion of impurities or contaminants in the environment on the sensor
    surface, calibration is recommended once a year.
• When ZN-THS1 -S is exposed over a long period of time at a high humidity of 80% or higher, the humidity
    measurement value may be offset.
    In that case, expose the product at room temperature and humidity for 24 hours prior to use.
• When ZN-THS1[][]-S is transferred rapidly between the places where temperature difference is large, condensation
    may occur on the sensor surface.
    In that case, the ZN-THS1[][]-S may not work properly.
    When the product becomes wet due to condensation, allow the product to dry in dry, room temperature environment
      before use.
• When using the ZN-THS1[][]-S under conditions with temperature of -20°C or less or with humidity of 90% or more,
     acceleration of sensor deterioration may occur.
• To avoid deterioration of sensor, avoid storing the product under high temperature and high humidity for a long period
     of time.
• Please don’t use the product in the environment to which organic chemistry material disperses.

*1 Power saving mode. The indicator is always OFF in default setting. (Turns ON with button operation.)
      Network communications with host devices cannot be made.
*2 This mode makes one-to-one network connection with Air Particle Sensor (ZN-PD[][]-S[]) and enables logging of the
      particle count value and thermal data simultaneously to the SD card.
      Network communications with host devices cannot be made.
*3 Automatically writes data to the SD card when reaching the upper limit of the internal memory and keeps recording
      until the capacity limit of the SD card. If the SD card is not inserted when the internal memory reaches the upper
      limit, recording stops. (Data can be output to the SD card by pressing the button after inserting the SD card.)
*4 This mode always records the latest measured values for the upper limit of the internal memory. (When the
      measured values exceed the upper limit of the internal memory, the data items will be deleted beginning with the
      oldest data item.)
*5 An alarm is shown when exceeding the upper limit value or lower limit value that has been set in threshold setting
      mode.
*6 Air particle sensor connection mode is excluded.
*7 If you use an SD card from another manufacturer, be sure to use an industrial SD card (with SLC-type flash memory)
      with high reliability and endurance. Please use an SD/SDHC Class 4 or higher card. (SDXC cards cannot be used.)
     Please note that you must confirm the operation of the SD card from another manufacturer yourself.
*8 Nickel hydride battery and alkaline battery can be used. Manganese batteries cannot be used.
*9 Battery life differs depending on measurement environment, sampling, operating mode, battery type or performance.
*10 The connector is type XW4B-02B1-H1, made by OMRON.
