8. Apply the low (zero) value. For a pressure input, this would typically
be open to atmosphere.
9. Enter the applied value in the Dead Weight / Tester Value field of the
Set Zero dialog. For SP on an absolute-pressure device, enter the
actual current atmospheric pressure.
NOTE
Apply pressure to both the high and low sides of the transmitter when
calibrating SP.
10. When the displayed Live Reading is stable, click Set Zero to calibrate
the zero reading. The Set Span window then appears
11. Apply the desired high value to the input (the top end of the expected
operating range).
12. Enter the applied value in the Dead Weight / Tester Value field of the
Set Span dialog.
• For SP on an absolute-pressure device, add the actual
atmospheric pressure, such as 300 + 14.73.
13. When the Live Reading is stable, click Set Span to calibrate the high
reading. The window advances to the Set Midpoint 1 window.
14. To perform a two-point calibration, click Done to complete calibration.
15. To calibrate midpoints, apply the desired pressure or temperature and
enter the applied value in the Dead Weight / Tester Value field.
Midpoint can be calibrated in any order.
16. When the Live Reading is stable, click Set Mid 1 to calibrate the
reading. The display advances to the Set Midpoint 2 window.
17. To perform a three-point calibration, click Done to complete
calibration.
18. To calibrate additional midpoints, apply the desired pressure or
temperature and enter the applied value in the Dead Weight / Tester
Value field.
19. When the Live Reading is stable, click Set Mid 2 to calibrate this
reading. The display advances to the Set Midpoint 3 window.
20. To perform a four-point calibration, click Done to complete calibration.
21. To calibrate a third midpoint, apply the desired pressure or
temperature and enter the applied value in the Dead Weight / Tester
Value field.
