Initiali zation
Send “Group Execute Trigger" to
reset the -004# which is arbitrarily
set at address 2 on Port O.
Nouii tell the program uihat to do if an
SRQ comes.
Most of the time it just sits here.
”spl(2>“ clears the SRQ. The -004 sends
a 66(42 H e x ) i f i t set the SRQ.
otherwise it sends a O. This
discriminates between other instruments
on the Port that could send an SRQ.
This command gets the thermometer reading
from the -004.
This command prints the reading-
Ends the SRQ handling and goes to wait
for another-
