6.5.2 Verifying the Nebulizer Gas Pressure
Before operating the detector, verify the nebulizer gas pressure setting.
NOTICE Operating the nebulizer with a gas pressure other than the
pressure specified for this nebulizer can damage the nebulizer and the
detector. After installation of the nebulizer, set the nebulizer gas
pressure to the pressure that is specified for your nebulizer. The
nebulizer gas pressure is defined on the gas pressure certificate that is
shipped with the nebulizer.
1. In Chromeleon, open the Command window. Navigate to the Gas
Regulator Pressure Nominal
parameter.
2. Check if the gas pressure on the nebulizer certificate matches the
nebulizer gas pressure set in the Gas Regulator Pressure Nominal
parameter.
If the nebulizer gas pressure deviates from the pressure on the
nebulizer certificate, enter the gas pressure from the nebulizer
certificate.
3. Close the Command window.
4. Monitor the Gas Regulator Pressure until it reaches the setpoint.
