Typical Scanning Rate
See table below. The measurement conditions are: averaged rate over 20 scans;
continuous scanning; alarm limits and Mx+B scanning set on all channels; logging data
to internal memory; and RS-232 communications set at 9600 baud. Measurements were
taken with short-circuit inputs on all channels, except frequency, which was taken with
5V at 15 Hz on all channels.
