The datalogger is a single channel datalogger which demonstrates the driver functionality for any of the following devices:

• Endress-Hauser Minilog-B datalogger
• Haake DC-50
• Sartorius CP324S scale

The datalogger starts measuring immediately once run.

Measurement

By default the measurement page displays a graph of the last 300 points. The timespan depends on the sample frequency.

Settings

The settings page displays the setting for the serial port:

• ComPort [COM1..COM4]
• Baudrate [1200..19200]
• Databits [5..8]
• Stopbits [1..2]
• Parity [none,odd,even,mark,space]
• BufferSize [1..128]

Changing these setting is effective only after stopping and restarting the datalogger.
