Opening the Data File with Excel
®
Depending on the region and language setting of your PC,
measurement data might be formatted incorrectly by Excel
®
when the
data file is opened.
This is sometimes encountered with German set as the PC language,
as a German date format typically utilizes a decimal (DD.MM.YYYY).
The EC300M utilizes a decimal as the radix, so a temperature of
31.1
is sometimes interpreted by Excel
®
as
31. Jan
when German is set as
the PC language.
If a data file is opened in Excel
®
and measurement data is incorrectly
interpreted as something other than a number, please follow these
steps:
1. Open a blank Excel
®
spreadsheet.
2. Go to the
Data
tab and select
From Text
