
Scan Delay : Indicates the minimum time to complete each scan step. For instance, if this is
set to 1.0 and a scan step completes in only 0.75 seconds, the scanner waits another 0.25
seconds before advancing to the next step.

Abort : This button causes advancement of the current scanlist to be stopped, allowing
configuration to be changed or a new scanlist to be defined.

Send Software Trigger : This button sends a software trigger signal to the device. If
Software is the selected Scan Trigger or Step Trigger , this will cause the device to begin the
next scan-step or scanlist iteration, respectively.
Results Field
Below the scanner configuration fields, a Results field is provided that is populated with data this
is collected during the sweep steps of the scanlist. The table consists of the following data fields:

Time : Indicates the IEEE 1588 time of the measurement.

Channel : Indicates the switch channel on which the measurement was taken.

Value : Indicates the data that was measured.

Units : Indicates the engineering units of the measurement data.
To the right of the Results Field are options that affect when data is displayed and what is done
with the data once the scan is complete.

Get Continuous : When enabled, all available data is pulled into the table as soon as possible.
This also disables the Get and Get All options.

Get button: When clicked, measurement data is immediately pulled from the FIFO memory.
Get Continuous must be OFF in order for this option to be available.
o
Get All : When Get All is selected, clicking the Get button causes all of the currently
available data to be retrieved from memory.

Get Count field: Indicates the number of data points that will be returned when the Get
button is clicked.

FIFO Count field: Indicates the number of data points available in the FIFO memory.

Clear Table button: When clicked, all of the data currently in the table is erased.

the pin that needs to be activated to cause the internal relay to actuate and connect to the pin
indicated. Horizontal and vertical scroll bars allow the user to navigate larger diagrams by
scrolling. The user may also change the magnification of the schematic. Near the upper right
corner of the web page is a size selection menu. By clicking on either the up or down arrow, the
