3.6.2 Accuracy for Some Typical
Conditions
For convenience in comparing the tradeoffs between
speed and accuracy, the accuracy is tabulated in Table
3-11 for the same frequencies, and the results tabu-
lated in the same arrangement, as the measurement
time tables. The data also appear as a graph of speed
vs accuracy for several frequencies, Figure 3-30.
Each curve shows the tradeoff for one test frequency.
Operating points are labeled according to the selected
measure rate (FAST, MEDIUM, SLOW). All of these
curves apply to the following conditions: R, L, or C
within basic ranges, D< < or Q> >1, display is BIN
NO., test voltage => 1.0 V, constant voltage NOT
selected, delay NOT programmed, measure mode
is CONTINUOUS, and the high-speed option used
(except for the dashed curve, which shows approxi-
mately the difference that this option makes). NOTE:
for display of VALUE, add 6 to 10 ms to the time.
