Hysteresis
Specify the desired hysteresis level for the peak valley processing algorithm.
8.3.6 Peak Valley Slice
The Peak Valley Slice DataMode stores a set of master channels and a set of slave
channels in the output data file. The set of master channels provides a peak/valley
sequence acquired using the user-specified hysteresis value and the peak valley
processing algorithm. For each peak or valley on any master channel, the eDAQ
lite
stores data samples for all channels (master and slaves) in the output data file. For
more information on the peak valley processing algorithm, see “Peak Valley
Processing Algorithm” on page 221.
NOTE
If no slave channels are required, it is more efficient to use the Peak Valley DataMode
(see “Peak Valley” on page 168).
Master Input Channel
Select the desired set of master input channels using CTRL to select more than one
channel. The master input channel data type must be 8-bit integer, 16-bit integer or
32-bit float.
Slave Input Channel
Select the desired set of slave input channels using CTRL to select more than one
channel. The slave input channels can be any data type.
Data Type
For 32-bit float input channels, select one of three available formats for data storage
and conversion.
NOTE
Using the integer data types requires that valid full-scale minimum and maximum
values are defined for each input channel selected for the DataMode.
Time Input Channel
Optionally, select a Time Channel computed channel from the provided list. For more
information on the Time Channel computed channel, see “Time Channel” on
page 150.
Data Type Description
32-bit float No conversion is necessary. Use the 32-bit float mode for computed
channels where full-scale estimates are uncertain or unknown.
16-bit integer Maintain the resolution of both the 12-bit and 16-bit A/D converters.
8-bit integer Lose significant resolution in both the 12-bit and 16-bit A/D converters.
Use the 8-bit integer mode only for a rough picture of channel
behavior.
