5.1 Starting a Measurement Session

To begin logging data, press and hold the START button (refer to Figure 3.1 for button location) until the logging indicator (usually a flashing LED or symbol on the display) appears. The device will start recording data at its pre-configured interval.

5.2 Stopping a Measurement Session

To stop logging, press and hold the STOP button until the logging indicator disappears. All recorded data will be saved internally and can be retrieved via USB.
