4.2.7 Dark current correction
Dark current correction is performed to ensure the accuracy of the measurement results. You should
perform dark current correction when the enviroment changes, which refer to temperature varies
much and installation location changes etc. as well as when you measure high absorbant samples (It
is recommended that perform dark current corretion before you start measurement to ensure the data
accuracy). The operation procedures are shown as follows:
A: Parameters setting page B: Dark current correction
Fig. 4.10 Dark current correction
Press to perform dark current correction on the parameters setting page in spectrum mode. It
will display ―system busy…‖. Then, about 10 seconds later, it will prompt the user with the message
―Please select Item‖, meaning dark current correction has finished, as shown in Fig.4.10.
4.2.8 Quit parameters setting
Press key on parameters setting page to return to the main menu of spectrum scanning, as
shown in Fig. 4.3.
4.3 Baseline correction
On the main menu of spectrum scanning, press key to start baseline correction at the set
wavelength range. Before starting baseline correction, put the blank sample into the sample
compartment. key can be pressed to stop baseline correction operation. If the wavelength
range has been changed, the baseline calibration should be done again.
