Error and Status Messages

Boot ROM 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.

Calibration Constants Corrupted! Continue?

Calibration Mode not enabled! See service manual.

You have not pressed the calibration button behind the instrument front panel

CALIBRATION SEAL.

Do not enable calibration unless you have all the equipment for a complete instrument calibration procedure, as defined in the Service Manual.

Cannot access specified drive [Drive] for Trend Link data!

You specified a disk drive for the Trend Link data file that cannot be used. Check the availability of the disk drive you selected for the Trend Link data file.

Cannot add [Channel] to the Trend Link Data Set! Check amount of free disk space available.

You have tried to add another tag (instrument channel) to the Trend Link data file when the disk space is insufficient.

To use this disk drive, delete unneeded files to create space for the new Trend Link tags and try again. To delete old Trend Link data files, see "Deleting Old Trend Link Files" in Chapter 5 of this manual.

Cannot add more grouped Trend Link Data Sets! Delete a Data Set(s) or create a new Data Set.

Your infolink.ini file specifies more than 25 instruments for a group instrument.
