A·20. MULTIPLE READING TRANSFER PROGRAMS.
•
A·2 1 . The rollowing programs show how to transrer
multiple readings rrom the 34S6A to the controller. The
programs are given in the HPL(9825A Controller) and
Enhanced Basic (9835A/B and 9845B Controller)
Language. The programs do the rollowing.
a. The 3456A is set up to do this:
I . Clear the 3456A and set SRQ Mask to bit I (Pro·
gram Memory Execution Complete).
2. Enter into memory
select 10 Number or Readings per Trigger, and
Single Trigger.
3. Execute Program Memory.
b. Read 34S6A Status and remain in a loop until Pro·
gram Memory has completed its execution.
c. Set up the 3456A to enable its System Output
Mode and scroll the internally stored readings starting
with 1110.
d. Store readings into variables.
