Vs C15 Startup Scenario - Agilent Technologies VS Series Operation Manual

NOTE
System Startup Function
Power up unit: 24 VDC
Turbo ramps to programmed RPM
Turbo reaches programmed RPM
Filaments 1 & 2 are checked and selected
filament activates
System background and turbo bearing
temperature are measured. If these
parameters meet the startup limits the 15
minute stabilization timer stops or times
out.
Refer to Section 2.2.5.1 "Calibration Set-Up Screen" on page 2-23 to properly set-up the
leak detector for auto-calibration.

VS Series Component Leak Detector
Table 4-6 describes the startup scenario for the RS232 interface
option.
Table 4-6 VS C15 Startup Scenario
If the system was recently calibrated before shut down, it can
be used for qualitative testing. Read the standard leak to verify
accuracy. For more accurate quantitative leak values, perform a
calibration 30 minutes after start-up.
To accurately read in the most sensitive decades of each
working range, perform a full internal or external calibration
after a 20-30 minute warm up.
The VS C15 Base unit is always in Test/Measurement mode.
