HELP:
Press
[F1]
for Help on a selected or highlighted field
or control. Alternatively, click the
[?]
button in the
upper-right hand corner of the window and click a
field or control to receive a Help message pertaining
to the item pointed to.
NOTE:
Approximately 5% under-range and over-range
capability is built into the output range by design. See
Output Specifications for more detail.
Enter the Output Update...
The
Output Update
sets the rate at which the output will be
updated with the scaled input measurement. The transmitter
will always update the output at this rate unless the
Output
Update Override
is selected when the input falls below the
Cutoff Frequency
.
NOTE:
The
Output Update
determines the time available for the
transmitter to capture the input signal. Therefore, the accuracy
of the calculated measurement will decrease as the
Output
Update
becomes faster. Using a slower
Output Update
allows
the transmitter to capture more of the input signal and calculate
a more accurate measurement.
Select the Output Update Override (Optional)...
Select the
Output Update Override
checkbox if the desired
behavior upon reaching the
Cutoff Frequency
is to update the
output immediately to 0Hz. Left unchecked, the time before the
output signal reaches 0Hz will be a function of the number of
Samples to Average
and the
Output Update
rate.
Select the Output Range...
The output terminals of this module are universal and may drive
DC current or voltage in the ranges ±20mA, 0-20mA, 4-20mA,
±10V, 0-10V, ±5V, and 0-5V. Approximately 5% under-range and
over-range capability is built into the output range by design.
Voltage outputs may drive 1000
Ω or higher loads, w
hile current
outputs may drive 525
Ω or less.
Enter the I/O Scaling values...
You may rescale the input range to use only a portion of the
input range to drive the output if desired. Be careful not to
reduce the input range too much, as resolution will be
proportionally diminished and noise/error magnified.
In the corresponding I/O Scaling field, enter the input signal
minimum/zero value to correspond to the output range Zero-
Scale value (i.e. -20mA, 0mA, 4mA, -10V, or 0V depending on the
output range selected). Also set the input range Full-Scale (i.e.
20mA, 10V, or 5V, depending on the output range selected). You
can optionally swap I/O Scaling values to configure a reverse
acting output response if desired. Note: Approximately 5%
under-range and over-range is built into each output range
selection.
If the I/O Scaling Zero-Scale and Full-Scale points are chosen too
close together, performance will be degraded.
