Calibration Parameters Verication
The instrument uses a set of predetermined calibration parameters to process ow signals. Most of these parameters should not
change. A data package shipped with the instrument (typically on a CD-ROM) contains the ST75/ST75V Delta R Data Sheet. This
contains the calibration parameters stored in the ow 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 below to record actual instrument parameters. Compare with the Delta R data sheet’s ST75/ST75V parameters.
Table 4. Diagnostic Test Sequence on Display
An issue may exist if parameters with an asterisk (*) have changed. Contact Customer Service if this is the case. If the parameters
have not changed, continue with the next section.
