Cd Scale Check And Adjustment - Jasco J-810 Hardware/Function Manual

wavelength lever will be visible from below, as shown in Fig. 4.10. If the main unit
is mounted on a table or bench, bridge the instrument across two tables or
benches to permit access to the adjustment screws.

(2) Correct the wavelength by adjusting the fine and coarse adjustment screws
located on the wavelength lever. Turning the screw clockwise shifts the HT data
to shorter wavelengths, and turning the screw counterclockwise shifts the data to
longer wavelengths.
(3) Measure the HT data of the neodymium glass sample to check the wavelength.
Note : If the instrument is moved, gently move it back to its original position, and check
wavelength accuracy again.

4.4 CD Scale Check and Adjustment

Note : Before checking the CD scale, warm up the instrument for about one hour after
turning the light source ON.
Note : Use a 0.06% (w/v) aqueous solution of ammonium d-10-camphor sulfonate as
the sample.
<Procedure>
(1) Start up the [Spectrum Measurement] program.
(2) Select the [Parameter...] command from the [Measurement] menu, and designate
the measurement parameters in Fig. 4.11.
