230! BEFORE TRIGGERING THE MODULE, DETERMINE IF IT IS READY BY CHECKING FOR

240! 'WAITING FOR TRIGGER' (BIT 5 OF THE OPERATION STATUS REGISTER).

250!

260! YOU COULD ELIMINATE THIS STEP BY SIMPLY INSERTING A PAUSE IN THE PROGRAM. HOWEVER, BY

270! CHECKING THE INSTRUMENT STATUS, YOU CAN AVOID TIMING PROBLEMS. ALSO, ANY OTHER OPERATIONS

280! THAT TAKE TIME WILL GIVE THE MODULE A CHANCE TO COMPLETE PROCESSING.
