3.3 Data Hold and Value Tracking

During measurement, you can use the following functions:

Premeu "HOLD" per congelar la lectura actual a la pantalla. Premeu de nou per alliberar-la.
Premeu "MAX/MIN" to cycle through maximum, minimum, and average recorded values.

3.5 Data Logging and PC Communication (TA642B/C)

Models TA642B and TA642C support data logging and real-time PC communication:

The device can store up to 1000 sets of measurement data internally.
Connect the anemometer to a computer using a USB Micro cable.
Install the provided PC software (compatible with Windows 7, 8, and 10).
The software allows for real-time data monitoring, displaying data tables, and generating live curve charts for analysis. You can also export data in .xlsx format.
