Error and Status Messages

Existing data file is not compatible for appending!

You tried to log data to a data file in the Append mode but have added or subtracted instrument channels from the configuration since the previous logging session.

Change the instrument channels back to their original settings, log to a new data file, or rename the original file. You cannot append a data file after adding or subtracting channels. You can, however, append a data file if you change channel functions or ranges.

File Size must be between 200 and 100000!

You entered an invalid File Size into the Auto Rollover dialog box.

Enter a value between 200 and 100000 k bytes.

Front Panel Display Failure! Continue?

Your instrument has detected a fault during internal performance monitoring.

This message does not appear under normal operating conditions. Note the message and click Yes to continue operations or No to terminate operations. If the fault recurs, stop operations, and cycle instrument power. If the fault still persists, remove the instrument from service and return it to a Fluke Service Center for repair, along with a description of the error message.
