Property

Description

AutoActivateUV_Lamp

If set to On, the deuterium lamp is automatically turned on upon power-up. Values: On, Off (default)

AutoactivateVisible_
Lamp

If set to On, the Tungsten lamp is automatically turned on right after power-up of the detector. Values: On, Off (default)

Autozero

Performs Autozero. The command is performed immediately, when issued manually, or at a Program time <0.000 min. With a program time of 0.000, the command is performed before the injection program; with a program >0.000, the command is performed at this program time.

DemoFileName

File name of the demo file. (May contain %d that will be replaced by the sample number)

PeakWidth

Expected minimum peak width in [min] (If you set the PeakWidth, you must also set the Step: see above).
