The Smart Rate is a feature used to trigger radio transmission of the meas-
ured data sooner than the normal or abnormal rate specified by the user.
This feature is used to construct a more accurate graph of the measured
process value vs. time than is possible with the fixed transmission rates,
while using less battery power.
If the process value changes by more than the entered Smart Rate amount
within the normal or abnormal sampling rate (whichever is active), then
the process variable is transmitted immediately. The normal/abnormal
transmit clock is then reset upon this transmission. If no Smart Rate
amount exceeding change takes place in the next normal/abnormal sam-
ple, then the next transmission will be the normal/abnormal transmit rate
period.
The amount entered is in the same units as were selected by the user to be
displayed on the Transmitter. If the measured process value does not
change by more than the entered Smart Rate amount within the time be-
tween the sampling rates (whichever is active), then the process value is
transmitted on the next transmit rate.
If changes in the process value, which exceed the Smart Rate Amount,
continue to occur, the process value is transmitted repeatedly.
The Smart Rate cannot be configured on Dual Analog Input Transmitters.
The Smart Rate can only be enabled using WMT.
1. Open the configuration dialog box (See Appendix A).
2. Click on the Sampling Rates tab to display the sampling rate informa-
tion as shown below.
3. Select the Enable SmartRate check box.
4. Enter the amount the process value needs to change, in order to trig-
ger a transmission to be sent.
5. Click OK to save and download the configuration changes to the
Transmitter.
To enable the Smart Rate, click the check-box labeled Enable SmartRate
for the correct input. The user will then be allowed to enter a "delta", or
amount changed, value which will trigger a transmission.
Once a value has been entered, click OK to save and download the con-
figuration changes to the Transmitter.
