LEAK SCREEN

Although most of the operation of the 6600 will be performed while in the Main Operating
Screen described above, at times, the Leak Screen is also accessed. When any of the outputs is
put into the "Leak" mode (after pressing GO), the display changes to the Leak Screen. A
sample Ps1 Leak Screen is shown below.

The parameters shown in the Leak Screen are:
a. Start: This is the reading at which the leak test was started.
b. Curr: This is the current reading of the output being leak checked
c. Timer: Shows the elapsed time of the leak test in minutes and seconds
d. Line 4 left-half: Shows the actual value of the outputs that are not in leak mode.
e. Instant Leak rate: Shows the instantaneous rate at which the output is leaking. For the
Ps1 and Ps2 leak checks this number is updated every 0.25 seconds and shows "0" for
leaks less than 20 ft/min. For the Pt leak check this number is updated every 3
seconds.
f. Per min. leak rate: This is the amount the output has leaked in the past full minute. It
is updated at the end of every minute on the timer. Until the first minute has elapsed it
shows "WAIT".
While in the Ps1 or Ps2 Screens, if the leak ever exceeds 2000 ft/min, the 6600 will
automatically trip out of the Leak mode and revert back to Control mode. It will then display
