HCI Measurement Program

3. Select softkey for parameter for which you want to extract Tdc.

Analysis result and Tdc will be displayed on the 4155/4156 screen as shown in Figure 9-9. Then program pauses. During pause, you can save these results to a 4155/4156’s DAT type file.

4. Select Continue function key to continue the program after each graph is

	displayed.
	If you select the ALL softkey in step 3, the 4155/4156 screen displays the graph
	for the next parameter of the same device number. And then program pauses.
	If you select the softkey to specify parameter in step 3, the 4155/4156 screen
	displays the graph for the next device for the parameter. And program pauses.
	This step is repeated according to entered number of devices and selected
	softkey.
