When high-level diagnostics are run, any errors detected are written to the
Diagnostic Errors file. The contents of this file can be printed using the Print File
soft key, or the file can be deleted using the Delete soft key.
If diagnostic errors appear, refer to the servicing information found in the
VM700T Video Measurement Set Service Manual .
The maximum capacity for the Diagnostic Errors file is 100 lines in a circular
file (scrolling past the last entry returns to the top line of the file). If the number
of errors detected causes the file to exceed this length, the earlier results are
scrolled out of the file buffer. When this occurs, the Diagnostic Errors file
includes a message stating that some of the text has been scrolled out of the file.
The Diagnostics Selection file lists the diagnostics the measurement set can
perform at power on. If installed options require additional diagnostics, those are
also listed. As received from the factory, all diagnostics are selected, but
bypassed by default for a quick startup. Refer to
Setting the Power Up Mode
on
page 1--9 for information on reconfiguring the measurement set to run diagnos-
tics at power on. Any diagnostic can be deselected by rotating the control knob
until the diagnostic is highlighted (see Figure 2--11, then touching the right side
of the highlighted line (above the words Not Selected). To return the choice to
selected, highlight the choice and touch the screen on the left side (above the
word Selected).
