Usage Method：

Method 1： None-drive usage (no special software required, easier to use.) ① Stop recording, connect the computer with a USB cable to download data. ② Copy data files in CSV format directly from the recorder, which can be opened by text processing software such as EXCEL or TXT.
Method 2： When you have more requirements for data analysis, please use the dedicated software to download the data, through the dedicated software you can view data reports, data curves, data statistics, record remarks and other information, but also output PDF data files. ① Copy the special software to the computer. It’s a green software, no need to install, open to use. ② Connect the recorder to the computer and set parameters when the recording is stopped. ③ Exit the recorder from the computer, placed in the environment that needs to be detected, and turn it on. ④ Stop recording, connect the recorder to the computer, view historical data, historical curves, data statistics, etc., and print data, output PDF and other format files.
