Performance Check: Data Station Type; Baseline (Abs 0 Line) Flatness - Jasco V-530 Hardware/Function Manual

(3) Remounting the sample chamber
a) Locate the sample chamber over the two positioning pins on the main unit and
move it all the way to the back.
b) Ensure that light is incident upon the center of the cell holder. To check it
visually, set the wavelength to 500 nm and place a piece of white paper in front of
the cell holder.
c) Firmly tighten the two fixing screws and close the lid.

Performance Check: Data Station Type

A performance check should be
instrument performance. If the instrument is not operating properly, conduct checks
and take corrective action after referring to the troubleshooting chart in Section 5. After
taking corrective action, run the performance check again to verify that the instrument
has been restored to normal.
Note: This section provides a simple description of operating procedures. For
details, refer to the Operations manual.

(3) Measure the baseline as follows.
a) Click [Measurement]-[Baseline...]. The [Baseline Correction] dialog box
appears.
b) Click the <Measure...> button to display the [Baseline Measurement] dialog
box.
c) Make sure that the sample chamber is empty and then click the <Start> button.
The baseline is measured and stored in the memory of the spectrophotometer.
