Performance Check: Intelligent Remote Module 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.

4.4.1 Baseline (Abs 0 line) Flatness

This check should be performed more than one hour after turning the instrument on.
(1) Select [Spectrum] from the main menu and measure the baseline of the entire
region after setting the following parameters. (Refer to Section 5-4 of the
Operations manual.)
This data is stored in the baseline memory.
Note: This data is used for correcting the baseline spectrum (0 Abs line) to be
measured in (2) below.
(2) Set the following parameter and measure the baseline spectrum (0 Abs line) with
the sample chamber empty. (Refer to Section 5-3 of the Operations manual.) A
measurement example is shown in Fig 4.1.
