MEDIUM AND FAST READING RATES..Jn medium reading rate, add 2 counts to number of
counts. In fast reading rate, use 2 counts for number of
counts.
' 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) ot ensure stated accuracy.
