MEDIUM AND FAST READING RATES
...
In medium rate, add
50
counts to number of counts. In fast
reading rate, for sinewave inputs 31000 counts and frequencies
>I00 Hz, the accuracy is
f
(0.4% of reading
+
30 counts).
NONSINUSOIDAL INPUTS
...............
For nonsinusoidal inputs 210,000 counts with frequency
components GI00 kHz, add the following
%
of reading to the
accuracy specifications.

Relative to calibration standard.
Applies to 4-wire ohms only.
When in fast reading rate with internal trigger and transmitting data out of the IEEE-488 interface, the 8840A
display must
be
blanked (command
Dl)
to ensure stated accuracy:
When offset control is not used, the number of counts are
5.7,
and
9
for
24
hour, 90
day,
and 1 year respectively.
