Instrument Setup
When the Instrument is opened by double clicking on it’s icon,
ChromGate
®
initializes the Smartline PDA Detector 2800 and switches on
the lamp(s). The Error LED goes off.
(The D
2
lamp first needs about 20 seconds warm up time)
In the Instrument Setup menu (accessible via Method / Instrument Setup)
the method’s main settings can be selected.
•
Time constant: 0.1, 0.2, 0.5, 1, 2, 5, 10 sec (default: 0.1 sec)
•
Sampling: 0.5, 1, 2, 5 Hz (default: 1 Hz)
•
Run Time: (default: 10 Min)
•
Acquisition Delay: (default: 0 min)
•
Channel: up to four separate channels can be activated for data
acquisition (default: one channel)
•
Bandwidth: for each channel bandwidth can be set separately
(default: 1 nm, recommended: 8 nm)
•
Detector (Time) Program: for every channel the wavelength can
be programmed separately – the entered wavelengths must be
within the scan range
•
Scan (If the PDA option is activated): Start, End and Bandwidth
can be chosen within the shown range (e.g. 190-1025 nm –
default: 200-500 nm)
•
Bandwidth: (default: 1 nm, recommended: 1 nm)
•
Signal Mode: Absorption / Intensity (default: absorption)
•
Acquire 3D data: If this option is not activated only the selected
channels will be recorded – spectra will not be recorded
•
Analog output scale: Here you can select which absorption
should represent 10 V output signal on both analog outputs
•
Autozero at wavelength change: Here you can decide whether an
autozero should be performed when the wavelength is changed
