•
Lines 17-29: Until another key is pressed to exit the loop, the
U4
command is issued and the HLL
data is collected. The IEEE 488 controller command
OUTPUT
sends
U4
to the MultiScan/1200, the
command
ENTER
requests the data, then the command
LINE INPUT
gets the data from the
IEEE 488 driver and places it in the variable
U$
. The
FOR
loop extracts the data for the individual
channels from the string
U$
and places them on the screen. Since the format of the volts data is
subtly different than that of the thermocouple data, two different
FOR
loops must be used to extract
the channel data. Time and date information is also available in the HLL data.
