VS Series Component Leak Detector
Quick external calibration - If a successful internal calibration
NOTE
has been performed it is unnecessary to do an external tuning
procedure since the tuning was done during the internal
calibration. Perform only an Offset and an External Calibration.
Must be active (level high, in order for the leak detector to execute
input commands (calibrate, zero...ECT.). Must in inactive (level
low), to execute commands via the front display panel or RS232.
Active after power up when the Turbo Ready condition is satisfied,
(operating at the programmed RPM) a successful emission for either
filament 1 or 2 an if the optional ConvecTorr gauge is functional. In
the event that the turbo is not at the programmed RPM or no emis-
sion is present for either filaments 1 & 2 the System Ready will not
be active. Take no leak rate measurements. The system is no longer
in test.
When the Busy output is active, the leak detector is performing one
of the following requested routines; waiting for stabilization or sta-
bilizing, internal or external calibration routine, tuning, offsetting,
reading the internal standard leak or zeroing. During the Busy con-
dition, the leak detector is not in test and no leak rate measure-
ments should be made.
Active when a successful ion voltage scan obtains an optimal
Helium peak signal for both internal and full manual external cali-
brations. Not locating a peak Helium signal results in a failed tun-
ing scan No Ion Peak Found (signal < 30% of the most sensitive
decade within the working range of operation). The Tune ok is
inactive upon power up or a failed tuning attempt. Do not test until
this condition is satisfied.
Active after a successful internal calibration routine, which consists
of an offset calculation, tuning routine, zeroing routine and a gain
calculation (Gain:.1 to 9.0). The Internal Calibration ok is inactive
upon power up or after a failed calibration attempt. Do not test
until this condition is satisfied.
