AZURA® Detector UVD 2.1S Instructions, V6820
Adjusting V/AU ratio
By assigning different absorption values to a voltage value of 1 V, you can
stretch or compress the chromatogram. You can choose the absorption
value out of 4 values:
0.01 AU
0.1 AU
1 AU
10 AU

operating hours
The number of operating hours is displayed and afterwards the status
display appears.
If the deuterium lamp has been operating for approximately 2000 hours
consider lamp replacement.
Using the analog port
To use the analog port for setting the wavelength of the detector, you
have to set a zero point and enter a scaling value.
Setting the zero point
The zero point is predefined by the applied voltage.
Device has been connected to GROUND.
ANALOG port has been selected.
