VS Series Component Leak Detector
Use with the internal calibrated leak option only. Routine consists
of an offset calculation, tuning routine, zeroing routine and a gain
calculation. Verify the system test valve is closed during the calibra-
tion process.
After power up and a successful internal calibration, the
NOTE
internal calibrated leak gain is applied to the system gain until a
successful external calibration is performed.
Tune Pin 20 (input) - Scan ion voltage for peak Helium
signal.
External Calibration Pin 22 (input) - Calculates the system
gain (.1 to 150) by exposing a external calibrated leak to the
leak detector.
Offset Pin 18 (input) - Establishes the zero reference point.
Isolate any external Helium sources from the leak detector
for proper system characterization.
The input routines, Internal Calibration, Tune and Offset can be
NOTE
aborted while in process. This is done by re-initializing the
input commands via the Front Panel display (Control Panel), I/
O or RS232.
