Figure 5-1 Reject and Audio Setpoints
Reject Set Points Activate and non-activate set points appear on the Home screen
inside the Set Point Status window. The status of the set points are
also available through the RS-232 line (see
Appendix A
“Communications Protocol”).
There are four possible set points. Three set points can be pro-
grammed to a leak rate value and one can be programmed to test
port pressure.
Set points may be turned ON or OFF (enabled or disabled) for each
set point. If a Reject Set Point is ON, then the rear panel output for
that set point goes active when its leak rate value is exceeded and
an activated red box indication appears on the Home screen.
Each set point is set to activate above or below the programmed
value. To activate the reject set point:
❑ Above the programmed value, select the >.
❑ Below the programmed value, select the <.
Audio Set Point Settings:
❑ On:
The audio tone rate increases proportionally with each
decade that the measured leak increases above the set point
(leak rate pass/fail specification). The audio volume control
is located on the Home screen.
