Configuring the Data Logger
All logged readings are saved in the counter’s internal flash memory or to an
external USB storage device after logging is complete. The readings are view-
able in trend (run) chart format while logging is in progress and when com-
plete.
Data logging occurs for a duration specified as a period of time or a number of
readings to be logged. Once enabled, the start of data logging can be delayed
for a period of time.
Specifying a Data Log File
Logged readings saved in internal flash memory or in external USB memory
are comma-separated values (CSV) in one measurement per line ASCII format.
A default path and file name (Internal\DataLog) is used if one is not specified.
The drive (Internal or External) is selected using the browse feature and the file
name is specified using the rotary knob and arrow keys to select or change
characters.
Pressing [Done] saves the path and file name and returns to the application
menu. Data logging will not start if an invalid path/file is specified.
Adding a Time Stamp to the Data Log File
A time stamp (t-Stamp) in the form:
yyyymmdd_hhmmss e.g. DataLog_20100925_105535.csv
is appended (On) to the file name when data logging completes or when the
(Stop Save) soft key is pressed. The time stamp also appears on the spreadsheet
tab when the data log (.csv) file is opened.
