Verify the Calibration Parameters
The instrument uses a set of predetermined calibration parameters to process flow signals. Most of these
parameters should not change. A data package located at the rear of this manual contains the “ST98 Delta R Data
Sheet”. This contains the calibration ST98 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 5-2 to verify parameters with the Delta R Data sheet ST98 Parameters.
Table 5-2. Diagnostic Test Sequence on Display
If parameters that have an asterisk (*) have changed, this may indicate a problem. Customer Service should be
contacted. If the parameters have not changed, continue with the next section.
