Appendix C
Additional Manual Regulator
The Sprint LC tester described in this Appendix has the ability to control
pressure with two manual air regulators. As in the standard Sprint LC,
there is an adjustment knob for the manual air regulator on the back of the
Sprint LC. There is also a second regulator attached to the air input port on
the back.
Two Channel Concurrent Sprint
If Sprint is a two channel concurrent tester the second regulator is used to
control the pressure for the second test port. This separates the pneumatics
for both channels so they are independently controlled. Since both
channels are controlled by one test program the pressure must be set the
same for both channels.
Single Channel or Sequential Sprint
Test pressure for each test program may be set using one of two
regulators. This allows test programs with two test pressures to be run
without having to stop and manually adjust the regulator.
The Test Parameter menu is modified to have a sub-parameter menu for
the Test Press line. Press the INCREMENT keypad (GoTo) to access the pop-
up menu. See the figure on the next page.
First set the Regulator line to either the HIGH or LOW regulator. The
HIGH regulator is the additional external regulator and the LOW regulator
is the standard regulator included with the base model Sprint LC.
Next highlight the Test Pressure line and set the pressure as normal. As in
a standard Sprint LC, air will be sent to the test port when setting test
pressure so the test port will need to be capped.
