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.
