General Tools and Instruments CIH20DL - Manual (Page 14)

DATA LOGGING WITH A COMPUTER
In addition to making and displaying real-time air speed, airflow volume and temperature
measurements and storing up to nine sets of these readings in nonvolatile memory, the
CIH20DL also can make and time-stamp up to 20,000 measurements over extended periods
of time at user-selected sampling rates. These measurements, called data logs, are stored
in a separate internal memory. They can be uploaded to a PC using the USB cable and
interface/driver/data logging software provided with the instrument.
After uploading, the data logs can be analyzed for trends and anomalies using the software’s
presentation options. Examples include graphical and tabular displays of data that make it
easy to spot excursions of air temperature or gradual decreases in airflow volume over time.
