Yes. The error number is 811.
As I worte before the first process was 4-wire resistance.
Looking for the bug I switched processes, starting with DC voltage measurement.
This time time out was at the first one. Again it appears after a random
time (# of loops).
Maybe it is a problem with DC voltage measurement configuration in HP1326
driver?

Both drivers' calls are subequently and on "ON CYCLE". In my case every 2
seconds.

Sir:
Please explain what you mean by "stop":
% Does it time out?
% Does the program hang and lock up?
% Does the program simply run through a few loops and then move on to the
rest of the program (the question here would be the termination conditions
for the loop in your program)?
