ST50 Mass Flow Meter
Calibration Parameters Verification
The instrument uses a set of predetermined calibration parameters to process flow signals. Most of these parameters should not
change. Included with the instrument is a data package containing 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.
An issue may exist if parameters withan asterisk (*) have changed. Consult with Customer Service if this is the case. If the parameters
have not changed, continue with the next section.
