The measured values are continuously written to the unit's internal data carrier every time they are modification. The stored measurement values (set value, main line, return line, external and flow rate) can be viewed directly on the screen as a trend graph. For detailed fault diagnosis, all saved measurement values can be saved to a USB data carrier at a later date.

Trend chart

On the basic screen under the register symbol (), the recording of the predefined measurement values for temperature and flow rate is displayed as a trend graph.


Temperature measurement graph (1)
  • [Set Value] (current)
  • [Main line]
  • [Return line]
  • [External] (if available)
flow rate measurement graph (2)
  • [Flow Rate]
Play/Pause (3)
  • Pressing the pause button () pauses live mode.
    → The trend chart can be viewed without continuous modification
    → The trend chart can be moved on the time axis by swiping left and right
    → The time axis can be zoomed in and out
  • Press the play button () to resume live mode.
    → The time axis automatically returns to the real-time trend graph
    → The time axis can be zoomed in and out

status of the unit (4)

  • Live: Live mode is active.
  • Hold: Live mode is paused.

Zoom-time axis button (5)

Shorter time range with a minimum interval of 1 min/div.

Zoom-time axis button (6)

Longer time range with a maximum interval of 80 min/div.

Backing up the data


NOTE!

  • It supports USB drives formatted with FAT, FAT32, exFAT, and ext2/3/4.
  • If saving to the USB disk is not possible, an appropriate warning appears.
  • Note that the export process can take up to 30 minutes, depending on the selected time period (2 weeks).
  • For each unit, a separate directory is automatically created on the USB disk, into which the recording files are written.
  • A new recording file is created each day.
  1. Close the USB drive.
  2. Select [Save/Load] > [Historical Data] > [Period Historical Data]
  3. Set the parameter to the desired value.
    The data for the current day is saved, including the selected previous period (days, weeks).
  4. Tap on the disk symbol () in the [Export Historical Data] parameter to start the process.
    → The data is written to the USB disk as a ZIP file. The information system is opened automatically and the current progress is displayed (→ Fig.). In addition, the process is displayed on the basic screen with the data carrier symbol flashing yellow ().
    → When the data transfer act complete, the user is informed and indicated by the white symbol on the data carrier ().
  5. Remove the USB disk.

Name the data

The file names on the USB disk are automatically created according to the following examples.

Directory folder:

  • His_<UnitBasicType>_<Serialnumber>_<YYYYMMDD_HHMMSS>.zip
    → His_HB-160Z61_2306-777_20230215_143823.zip

Recording file:

  • His_<UnitBasicType>_<Serialnumber>_<YYYYMMDD>.csv
    → His_HB-160Z61_2306-777_20230215.csv
