Key Points
Signal Path Compensation. For maximum accuracy at any time, run the
signal path compensation routine just before taking critical
measurements. To meet accuracy specifications, run the routine if
the ambient temperature changes by 10° C or more.
Before running the routine, disconnect any probes or cables from the
channel inputs. Then, push the Signal Path and OK Compensate
Signal Path screen buttons to confirm that you are ready to proceed.
The routine takes several minutes to complete.
