Corona Veo RS Detectors
When
•
After installation or replacement of the nebulizer
•
If the nebulizer gas pressure has fallen outside the specified
pressure for the nebulizer
•
If you use the gas regulation modes (only available when operating
the detector from a chromatography data system)
Preparations
Make sure that the nebulizer is installed.
Follow these steps
1.
If the pump flow is turned on and the detector is in Run Mode
a) Turn off the pump flow. Wait several minutes for the detector
pressure to stabilize.
b) In the Run Mode Menu on the detector display, select the Exit
soft key to stop the Run Mode and return to the Main Menu .
TIP If you operate the detector from a chromatography data system,
disconnect the detector to unlock the display functions and access
the
Main Menu .
2. In the Main Menu , press the Gas soft key to navigate to the Gas
Regulator screen and display the gas regulator parameters.
TIP Write down the nebulizer gas pressure reading indicated as the
Pressure parameter for later monitoring of the pressure.
3. On the Gas Regulator screen, select the Setpoint parameter and set
the pressure to the value that is defined on the gas pressure
certificate.
4. Select the Save soft key to save the new pressure setting. Press Exit
to return to the Main Menu .
5. Wait until the gas pressure reading has stabilized and reached the
setpoint. On the Diagnostics screen, monitor the pressure reading of
the Gas Pressure parameter (see section 6.4.2.1, page 112 ).
