If you start the data gathering with T-PSV, the data of the Excel cell will be changed.

Note (1) When you modify/change the configuration file for the T-PSV, close the Excel file

once, and open the file again to setup the links.

However if the cell format is specified in Excel, the displayed data format will be

based on the Excel's setting.
