The Abnormal Sampling Rate is identical to the Normal Sampling Rate
with one exception. The Abnormal Sampling Rate only applies while the
Transmitter is in an abnormal condition (see 6.6 Selecting the Normal
Upper and Lower Values). This allows an increase or decrease of the fre-
quency of information you receive depending on the operating conditions
of the process being monitored.
In order to properly set the Abnormal Sampling Rate, determine how often
updates are needed from the Transmitter when the process being moni-
tored is operating under normal conditions. The Transmitter has a select-
able range of 1-5, 10, 15, 20, 30 seconds and 1 minute. Figure 6.10 is an
example of how the device switches sampling methods from Normal Sam-
pling Rates to Abnormal Sampling Rates. Note how the first abnormal
sample is taken a few seconds after the Normal Upper Value set point is
exceeded. The next sample will then follow this sample by 5 seconds (or
whatever the Abnormal Sampling Rate is set to). These samples will con-
tinue at this interval until the process value drops below the Normal Upper
Value set point.
Once the process value drops below this set point the sampling rate will
return to the Normal Sampling Rate. Also, the Abnormal Sampling must
be equal to or faster than the Abnormal Transmission Rate.
The user should also note that the transmission time depends on the sam-
ple rate, and when the process variable is sampled. If the Normal Sam-
pling Rate is 30 seconds, then the process variable may be above the Nor-
mal Upper Value for up to 29 seconds before abnormal condition is de-
tected. This means that the transmission could be as late as 29 seconds
after the process variable exceeded the Normal Upper Value.
Follow the menu map below.
6.4: Selecting the Abnormal
Sampling Rate*
NOTE
If the device is not configured to check for abnor-
mal process conditions using the Sampling Bands
(section 6.6.2), the Abnormal Sampling rate is not
used and this section can be ignored.

Rate Setting

* Indicates that Menu is Disabled if Wireless Management Toolkit is detected. (See Appendix A)
If you have the Wireless Management Toolkit software this menu option
will not be accessible via the Transmitter once the Transmitter detects
that the software is being used (See Appendix A for more details). An
explanation of how to select the Abnormal Sampling Rate using the
Wireless Management Toolkit software can be found in section 6.7.

Sampling Rate from the Trans-
mitter*
NOTE
Once the WMT has been used to configure the
Transmitter, this menu option will be disabled on
the Transmitter LCD Menu.
