Signal Calibration
The Signal Calibration page (figure 20) is displayed by clicking the Signal Cal. Tab in the SVI Calibration
window. This page allows the user to recalibrate primary signal and output pressure sensors, as well as
secondary signal if the process controller function is enabled. These sensors are calibrated at the facto-
ry and do not usually require re-calibration, but if needed, this page provides a convenient method. The
Reset to Factory button returns the calibrations to those that were set before delivery of the SVI.
The currently measured values of the primary input signal, secondary input signal (if the process con-
troller is enabled), and output pressure are displayed and can be compared to reference signals to
determine whether re-calibration is necessary.
After completing calibration from a page, click:
•
OK button to accept changes entered, download to SVI, and exit to manual mode.
•
Cancel button to discard changes entered and exit to manual mode.
