Calibration Parameters Verification
The instrument uses a set of predetermined calibration parameters to process flow signals. Most of these parameters should not
change. A data package located with this manual contains the “ST50 Delta R Data Sheet”. This contains the calibration parameters
stored in the flow transmitter at the factory. To verify that these parameters have not changed, complete the following:
1. Identify the appropriate Delta R Data sheets by serial number of the instrument.
2. Press [D] [ENTER] to examine each of the parameters. The [ENTER] key allows scrolling one message at a time. Use
Table 4 to verify parameters with the Delta R Data sheet ST50 Parameters.
