If the "measured Helium signal" is
≥
Reject setpoint,
the part is rejected.
If the "measured Helium signal" is
≥
Warning setpoint and
< Reject setpoint, the part is accepted but a warning*
signals that the measurement is approaching the Reject level.
If the "measured Helium signal" is < Warning setpoint, the
part is accepted.
Note: The test parameters can be programmed
independently for the 10 different file # available.
A test ticket is printed if a printer is connected (see
B 40
) and if
this parameter is activated.
When automatic tests are performed for a selected part reference,
each individual test is identified by a number called TEST REFERENCE.
Two kinds of test references are available:
TEST Nr : test number automatically incremented after each cycle.
SERIAL Nr :serial number incremented after each cycle but manually
modifiable and validated at the end of each test (see
page 12
).

When the detector is changed to test mode, the "test time" is
counted down. After the test time, the Helium signal is
measured (instantaneously) and the result analysed according to
the next parameters.
