Badger Meter SRD/SRI Valve Positioners - Manual (Page 64)

Temperature Calibration
Temperature Calibration (Calibrate menu) is needed whenever the "Printed Circuit Board" is replaced . Refer to the positioner
users manual, since special tools may be required .
This function calibrates the temperature of the internal electronics module . It is only intended to be performed in a bench
environment . A temperature probe is required to perform this calibration . After pressing Continue to proceed, measure the
electronics temperature with the probe . Enter this value in the edit box and then press Continue . Temperature calibration is
now complete .
Output Calibration
This function performs calibration of the Output of the Position Feedback option board . This operation is typically done on the
bench and may require special tools and special electrical connections . See SRD991 User Manual for more information .This
function is only allowed at workshop security level .
Output – Zero Calibration
This function performs calibration of the Output .
Output – Span Calibration
This function performs calibration of the Output .
Air Supply Pressure Calibration
Sensors (pressure) calibration (Calibrate menu) is needed whenever the "Printed Circuit Board" is replaced . This operation is
typically done on the bench and may require special tools . See the positioner users manual for more information .
Air Supply Pressure – Zero Calibration
This function calibrates the Air Supply Pressure sensor:
1 . Regulate air supply to LOW supply pressure value . Enter this value in the edit box and press Continue .
2 . Regulate air supply to HIGH supply pressure value . Enter this value in the edit box and press Continue .
The air supply pressure calibration is now completed .
Air Supply Pressure – Span Calibration
This function calibrates the Air Supply Pressure sensor:
1 . Regulate air supply to LOW supply pressure value . Enter this value in the edit box and press Continue .
2 . Regulate air supply to HIGH supply pressure value . Enter this value in the edit box and press Continue .
The air supply pressure calibration is now completed .
Output Pressure Calibration
Sensors (pressure) calibration (Calibrate menu) is needed whenever the "Printed Circuit Board" is replaced . This operation is
typically done on the bench and may require special tools . See the positioner users manual for more information .
Output Pressure – Zero Calibration
This function performs calibration of the Output Pressure sensor . To perform this procedure proceed as follows:
1 . Regulate the Output Pressure to LOW pressure value . Enter this value in the edit box and press Continue .
2 . Regulate the Output Pressure to HIGH pressure value . Enter this value in the edit box and press Continue .
The output pressure calibration is now completed .
Output Pressure – Span Calibration
This function performs calibration of the Output Pressure sensor . To perform this procedure proceed as follows:
1 . Regulate the Output Pressure to LOW pressure value . Enter this value in the edit box and press Continue .
2 . Regulate the Output Pressure to HIGH pressure value . Enter this value in the edit box and press Continue .
The output pressure calibration is now completed .
