MCOUNT?
196 Chapter 6 Command Reference
Example The following program performs the real-time NULL math operation on 20
readings. After executing the NULL command, the first reading is triggered by
line 50. The value in the OFFSET register is then changed to 3.05. The 20 read-ings
are triggered by line 90 and 3.05 is subtracted from each reading.
10 OPTION BASE 1 !COMPUTER ARRAY NUMBERING STARTS AT 1
20 DIM Rdgs(20) !DIMENSION ARRAY FOR 20 READINGS
30 OUTPUT 722;"PRESET NORM" !PRESET, NRDGS 1,AUTO, DCV 10
40 OUTPUT 722;"MATH NULL" !ENABLE REAL-TIME NULL MATH OPERATION
50 OUTPUT 722;"TRIG SGL" !TRIGGER 1 READING, STORED IN OFFSET
60 OUTPUT 722;"SMATH OFFSET,3.05" !WRITE 3.05 TO OFFSET REGISTER
70 OUTPUT 722;"NRDGS 20" !20 READINGS PER TRIGGER
80 OUTPUT 722;"TRIG SYN" !SYN TRIGGER EVENT
90 ENTER 722;Rdgs(*) !SYN EVENT, ENTER NULL CORRECTED READINGS
100 PRINT Rdgs(*) !PRINT NULL CORRECTED READINGS
