2.6.4
This button is used to send the Power-up/Halt command to the CS5461A. The device will return to normal operating
mode and halt any conversions that are being performed at the time.
2.6.5
The Temperature Settings window is used to adjust the CS5461A’s Temperature Offset register (T
perature Gain register (T
(°F) and to improve temperature measurement accuracy. Refer to the CS5461A data sheet for the details of the On-
chip Temperature Sensor.
2.6.6
This window provides a means to write the conversion result data to a .txt file for later analysis or print out. The file
path and name will be shown in Filename field. The Open File button is used to open a new or existing .txt file for
writing data. Each time the Write Data button is pressed, the result data is written to the file and the Number of Lines
Written field will be incremented by 1.
2.7
The CS5461A features a pulse-rate energy output. The CDB5461AU has the capability to demonstrate the function-
ality of this output in the Pulse Rate Output window shown in Figure 11. The Pulse Rate Output window can be ac-
cessed by pressing <F5>, or by pulling down Menu, and selecting Pulse Rate Window.
2.7.1
This box allows the user to select the length of time over which pulses will be collected.
2.7.2
This box allows the user to average a number of integration periods.
