Alphanumeric Control and Display
Panel (ACDP) operation
This menu is used to:
- set up the automatic test parameters for 10 part references
memorized as file # 1 to 10,
- select the part to be tested among the 10 memorized,
- modify and check the date and time which are displayed and
printed on the control tickets.
As indicated above, 10 part references can be memorized with
their associated automatic test parameters.
Access to these files is allowed whichever test mode of the detector
(AUTO or MANUAL) has been selected.
An eleventh reference called FILE BYPASS, available in the MANUAL
mode only, allows to reduce the number of menus displayed
because it has no automatic test parameter.
16 alphanumerical characters introduced by connecting the detector
to a (PC) microcomputer allow to customize the 10 part references
(see
page 18
).

Background setpoint
Roughing time
If the Helium signal, when not in a cycle and at the time
the cycle start is activated, is greater than the "background
setpoint", the test cycle is cancelled and an empty cycle is
requested to "clean" the detector (optional, selected with
a switch inside the detector; see page
24
).
The background setpoint can be useful for high sensitivity
tests (reject setpoint in the 10
-9
to 10
-10
mbar.l/s range).
If the detector has not changed to test mode after the
"roughing time", the cycle is stopped and the part rejected
for Gross Leak.
