*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 a one-to-one network connection with Air Particle Sensor (ZN-PD[][]-S[]) and enables logging of
      the particle count value and differential pressure 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 When using a third party SD card, it is recommended to use a reliable and durable industrial SD card (SD standard
      or SDHC standard (not compliant with SDXC standard), Class 4 or higher, flash memory type SLC or MLC type).
      You must confirm the operation of the SD card 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.
