Additional Measurement Error when D>0.01:
Add 5D% (when LOW test signal level is used,
10D%) to the accuracies for HIGH SPEED C
and HIGH SPEED L.
Measurement Time:
Typical
characteristics are
shown
in
the
figure below:
Additional Measurement Error when D > 0.1:
Multiply C, L, or D accuracy by (1 + D^)
Settling Time after measurement range change:
Approximately 60ms
Settling Time after frequency change:
Approximately 300ms
Settling Time after Test Signal Level Change:
