reader attached to a host computer.
2.3.9.2 Continuous Logging
The Continuous Logging feature will log snapshots of the same data being displayed on
the Certifier Parameter Screen and log it into a file on an SD Flash card. The logging
rate is once per second. Only data displayed on the Certifier Parameter Screen will be
logged. See section 2.3 on how to add or remove parameters. The data is exported into
“comma separated value” (CSV) format, readable by many common spreadsheet and
database applications. See Advanced Features Menu for selecting file delimeters other
than commas.
The Continuous logging feature requires an SD Flash card.
To initiate Continuous logging:
Press the Print/Save button on the Certifier test system keypad.
Select Continuous from the Logging Features section.
You may choose to Add Comments if you would like to annotate the data.
Click OK, add comments (if selected) and name the file.
The Certifier test system will continue to log data until the Print/Save button is
pressed again or until the SD Flash card fills up.
Access the data by connecting the Certifier test system to a host computer via USB, or
by removing the SD Flash card from the Certifier test system and inserting it into a card
reader attached to a host computer.
Note: If the pause button was pressed prior to continuous logging, a slight delay may
be noticed in the start of the data acquisition.
