    4) Combining GL100-WL and GL840

    GL100-WL can now be connected to the GL840 as a remote sensor using the WLAN feature. GL840 supports up to five units of the GL100-WL

     

    5) Useful function

    Various functions, such as a bar chart data display, alarm output function, navigation function, and networking features, are available in the GL840 to assist be conveniently used

     

    6) Maximum sampling interval of up to 10ms

    Provides faster sampling rate 10ms for voltage measurement

     

    7) Built-in 4GB flash memory with SD card support

      • The built-in Flash memory is available for units with serial numbers C604XXXX or later. Please contact your local representative for more information.
      • SD memory card cannot be used on the SD card slot while the wireless LAN unit (opton B-568) is used.
      • – When the RING mode or external pulse synchronization sampling is selected for recording, the backup function is not available.
        – When there are meany number of active channels, the sampling time is fast, or the backup interval is long, it may take time to closing the data file after recording stops because the size of the data to be backed up becomes large.
        – When saving file to FTP server using wireless LAN connection, backup may fail depending on the communication condition.
        – Available sampling speed is the 100 ms or slower when using the CSV format.
        – When backup is enabled and data file format is specified with CSV format, SD memory card exchange (hot-swapping) and RELAY recording are not available.
      • Size of the capture data will be limited to 1/3 of available memory.
      • Display mode is switched every time the dedicated key is pressed. In magnified digital value mode, the
        displayed channel number can be specified. In the waveform display mode, the changing of the time scale will
        be effective from the point of the next displayed data
      • Rating under maximum power consumption using the AC adapter, with LCD display on, and battery pack(s)
        being charged.
      • Excludes AC adapter and battery pack.
