*Table 3 Subroutines
1: Beginning of Subroutine (P85)
;Subroutine to measure "zero"
1: 1 Subroutine 1
2: Do (P86)
;This prevents calling subroutine
1: 11 Set Flag 1 High ;until user sets flag 1 low again.
3: Z=F (P30)
;Set counter use for average to 0
1: 0 F
2: 5 Z Loc [ count ]
4: Z=F (P30)
;load 4000 into
1: 4000 F ;input location
2: 7 Z Loc [ 4e6 ]
5: Z=X*F (P37)
;Multiply by 1000 to get (4*uS/S)
1: 7 X Loc [ 4e6 ]
2: 1000 F
3: 7 Z Loc [ 4e6 ]
6: Z=F (P30)
;Load Gage Factor into input location
1: 2 F ;Enter the actual Gage Factor here
2: 6 Z Loc [ GF ]
7: Z=X/Y (P38)
;calculate multiplier to use with strain
1: 7 X Loc [ 4e6 ] ;calculation
2: 6 Y Loc [ GF ]
3: 8 Z Loc [ Mult ]
8: Beginning of Loop (P87)
;Loop through 5 times to obtain average
1: 0 Delay ;zero reading
2: 5 Loop Count
9: Z=Z+1 (P32)
;Increment Counter used to determine
1: 5 Z Loc [ count ] ;when to output
10: Full Bridge (P6)
;Measure Strain Gage
1: 1 Reps
2: 2 ± 15 mV Slow Range
3: 1 DIFF Channel
4: 1 Excite all reps w/Exchan 1
5: 5000 mV Excitation
6: 1 Loc [ mVperV ]
7: 1 Mult
8: 0 Offset
11: IF (X<=>F) (P89)
;Check for last pass through loop
1: 5 X Loc [ count ] ;to set output flag
2: 3 >=
3: 5 F
4: 10 Set Output Flag High
