Key Points
Signal Path Compensation. For maximum accuracy at any time, run the
SPC routine just before taking critical measurements. To meet accuracy
specifications, run the routine if the ambient temperature changes by
10 °C (18 °F) or more.
Before running the routine, disconnect any probes or cables from the
channel inputs. Then, push the Signal Path and th e OK Compensate
Signal Path screen buttons to confirm that you are ready to proceed. The
routine takes several minutes to com plete. (See page 4.)
