Appendix B: Operator Performance Checks

B–12

1502C MTDR User Manual

If the instrument failed Jitter or Risetime checks, it is probably still adequate for

all but extremely precise distance measurements. If it failed the Horizontal Scale

check, you should not use the instrument until the cause of the failure has been

identified and corrected.

All of the previous checks only test the major functional blocks of the instrument

that could prevent you from being able to make measurements. It is possible for

the front-panel controls or the LCD to have problems that would interfere with

controlling or displaying measurements. Most problems of this type would

become evident as you perform the checks. If you suspect a problem of this

nature, you should have the instrument checked by a qualified service technician,

using the diagnostics in the 1502C Service Manual.

If the instrument passed all of the previous checks, it is ready for use.
