10.6 Calibration Data
The Calibration Data Application is where the calibration data for each transducer is stored and
amended. The Serial number (S/N), Zero offset (Zero) and Span offset (Span) can be seen in this screen.
The date of calibration, the calibration interval and the certificate number can be entered by pressing
the corresponding button, then saved by pressing the Check [
] button. To revert back to the factory
calibration, press the “Restore Factory Cal” button. To view the calibration data for each transducer press
the “Channel” button at the top and choose a transducer from the resulting channel selection menu.

10.7 One Point Cal Application
A single point calibration (usually a zero point calibration) of each transducer installed can be
accomplished in “One Point Cal” Application. The transducer channel is chosen by pressing the
“Channel” button at the top of this screen, and then selecting from the list of installed transducer
channels. For gauge pressure simply expose the reference and the Measure/Control port of
the CPC3050 to atmospheric pressure and then press the “New Value” button and enter zero
(0) using the keypad. For an absolute transducer apply a known reference pressure between
600 mTorr absolute and 20% of the active transducer’s span to the Measure/Control port of
the CPC3050, press the “New Value” button and then enter the reference pressure (known true
pressure) using the keypad. If you want to save the value in the transducer, press Save.
Notice the reference symbol [
], this is the reference level of the
instrument.
