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 ).
Store Initial State
Set the store initial state parameter to yes to always store the initial state at the start
of each test run.
8.3.4 Message Logger
Use the Message Logger DataMode to store one or more input message channels in
the data file.
NOTE
The Message Logger supports the PC Card data storage option only.
Input Channel
The input channel is limited to message channel sources, which are all 8-bit unsigned.
8.3.5 Peak Valley
The Peak Valley DataMode stores multiple channels of peak and valley sequences in
the output data file. The eDAQ
lite
acquires peaks and valleys from triggered or
un-triggered time history data streams using the user-specified hysteresis value and
the peak valley processing algorithm. For more information on the peak valley
processing algorithm, see
“Peak Valley Processing Algorithm” on page 221 .
Input Channel
The input channel data type must be 8-bit integer, 16-bit integer or 32-bit float.
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.
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.
