Chapter 5. Calibration using IEEE 488 SCPI
10. SXY = SXY + (COMP403/405(n) * STANDARD_PRESSURE(n))
To calculate slope and offset shifts:
1.
2.
5.2.4.2 To Accept New Slope and Offset
1. IF ABS(100 * (M - 1)) < MAXSLOPE
AND ABS(C) < MAXOFFSET
THEN
NEWSLOPE = OLDSLOPE * M
NEWOFFSET = OLD C
5.2.4.3 To Calculate New Residual Correction Values
1. FOR n = 1 to MAXPTS
2.
3.
4.
5. NEXT(n)
6. R(0) = 0, all other missed residuals set to 0.
5.2.4.4 To Install New Calibration Data
Send NEWSLOPE, NEWOFFSET and R(0) to R(11) to ADTS 403/405 using CAL:ADJ
command.
