Leak Detection Sequence:
1) Press the start button.
a) The "Evac" diode comes on and the test object is evacuated.
Pre fill evacuating time is set and adjusted by a timer in Sensistor
ISH2000.
b) The "Fill" diode comes on and the "Evac" diode goes off.
Note: The "Evac" diode goes off shortly after the "Fill" diode
has come on.
Test object is now filled with tracer gas. Filling pressure is
controlled by the gas bottle regulator.
2) Search and locate leak(s).
3) Press stop button.
a) The "Evac" diode comes on and the test object is evacuated.
