(15) Click the (Pre Scan) button on the measurement toolbar. A pre-scan will thus be executed.
(16) Click the (start measurement) button on the measurement toolbar.
(17) When a spectrum is acquired, carry out peak detection and determine the peak wavelength.
Make sure it is within the specification.
Specification: 435.8 1 .5 nm
Now proceed to check of the EX wavelength accuracy.
NOTE: If the photometric value obtained under the abovementioned conditions is excessive
(“***.*” is indicated for the photometric value) due to brightness of the room, try changing the
photomultiplier voltage to 700 V.
