Invalid history data format in file. You recalled a file that does not
contain data in the correct format. This occurs when a file is recalled
that happens to have the correct extension for a history file (and thus
shows up on the RECALL RESULTS page) even though it is not a
CTS 710 history file.
Loss of added signal. You have selected an externally generated
tributary signal, but no valid signal is present.
Loss of external clock. You have selected an external clock source
that does not have a valid clock source attached.
Measurements are running, recall not allowed. You tried to recall
instrument setups from memory or disk while a test is running. Wait
until the test is completed and then recall the file.
Measurements are running, results cannot be saved. You attempted to
save results to disk while a test was running. Wait until the test is
completed and then save the results to disk.
No Result file with ’.RES’ extension found. This message appears when
you select Disk (on the RECALL RESULTS page) but the disk does
not contain any results files.
Not available without tributary option. The requested action requires
that the Add/Drop/Test tributary option be installed.
No Test file with ’.TST’ extension found. This message appears when
you select Disk (on the RECALL PASS/FAIL TESTS page) but the
disk does not contain any pass/fail test files.

numeric value larger than the maximum value.
