Branch to subroutine to monitor laser status
Send Device Clear; Send Remote Enable
Send 10740A Backplane Reset, preset x-axis counter and
select normal resolution
Transfer x-axis counter (10760A) contents, including error
bits to 10745A.
If SRQ false; reference error bit must be false; laser ready
Read 10745A STATUS BYTE to verify that it is
asserting SRQ.
If 10745A not asserting SRQ; alert operator
Isolate reference error bit
If true, 5517A not READY
Try Again
Otherwise, use subroutine "check" to identify remaining error
Return to step one if only ovf error true
Alert operator that SRQ asserted by other device
Return to step 0 of CONTINUE pressed
