function for the setting of limit line, making it easier to test products. Thus, when large
quantities of products need to be tested, it only needs to replace DUT and observe limit line to judge
whether the product is qualified or not. If the limit line is red, DUT is disqualified; if the limit line is green,
DUT is qualified. What’s more, it can avoid repetitive edit by saving/recalling the limit line. Limit line in
Figure 3.28 has been edited.

Alarm
: The Tester also has alarm function that users can turn on or off this function by [Alarm Off
On] when limit line is in use. If test curve of DUT exceeds the set limit line when the alarm function is
turned on, Tester will raise a “beep ... beep” alarm, through which users can judge whether the product
is qualified or not. Test curve in Figure 3.29 has exceeded the set limit line.
