Creating an Instrument Control Method 159
WL shows two different values: the current wave length and the signal.
The wave length’s unit is nm; the signal unit depends on the unit that has
been chosen in the ASM2.1L configuration for the detector.
The right-handed part of the UV section allows for direct control of the
detector, independently from the method setup. During a run this part is
not accessible beside the autozero (AZ) button.
WL: (Direct Control)
Enter the desired wave length for the detector click on the button
to change the wave length in the detector. If the wave length is out of the
acceptable wave length range, an appropriate error message will be
shown.
Fig. 235 Error message Wavelength out of range
Lamp OFF / Lamp On button (Direct Control)
This button allows for switching off or on the detector lamp. The button’s
labeling indicates, what will happen if the button is pressed; it does not
show the lamp status! If the lamp is on, the button shows “Lamp OFF”,
because the lamp will be switched off, if you click on it. It shows “Lamp
ON” if the detector lamp is off – clicking the button will switch on the
lamp. While the deuterium lamp is heating, the (inaccessible) button
shows “Heating”.
AZ button (Direct Control)
If you click on this button, the detector will perform an autozero, which
means, the current signal will be set to 0 (zero). This button will also be
active during a run, please be careful then: Clicking this button if a peak
elutes will make the peak information (area, maybe also retention time)
unusable.
Valve(s)
The left-handed part of the Valve(s) section shows the valves current
position.
Fig. 236 ASM2.1L status tab – Valve(s)
Position: (Status)
The current position of all configured valves will be shown. For each
valve the name given in the configuration is shown. If the AMS2.1L is
configured using the “Auto Configuration” option, the default name for a
valve is “Valve”, followed by an extension for the valve’s position in the
ASM2.1L case (L = left, M = middle, R = right). For Knauer two-position
valves the position can be either I (injection) or L (load), for Valco twoposition
valves A or B. For multi-position valves the position can be 1 –
16, depending on the valves configuration.
The right-handed part of the Valve(s) section allows for direct control of
the valve(s), independently from the method setup. During a run this part
is not accessible.
