Verifying Modbus Output Values
Perform the following to verify the accuracy of the Modbus output
values:
1. After the FlowShark RT has been activated and the Modbus
interface is live, allow an adequate period of time for the
FlowShark to take and store several data samples.
2. Collect the stored data following the procedure described in
Collecting Data from the Monitor in Chapter 6, Configuration
and Activation.
3. Compare the collected data to the Modbus output values. Whiel
the values should be similar, but not exact. The values stored to
the FlowShark RT monitor memory and collected by Profile
are an average of the readings taken between the data storage
intervals. Therefore, the values will not be equal to the real-
time values provided through the Modbus interface.
