beam path. Press the
icon to open the program for the wavelength accuracy test.
Confirm with
to start the automatic measuring process. After testing, the result of the
measurement will be displayed (see Figure 90). The actual values are compared against the
reference values stored for the built-in holium oxide filter. The maximum allowed deviation is
+/- 1.0 nm. If all of the values are within the specified confidence intervals, the test will be
rated "Passed."

Via the
icon, the result of the test can be printed as a certificate or stored in the form of a
CSV- and PNG-file on an external storage medium.
If the results of the check exceed or fall below the allowed tolerances, please contact the
manufacturer or your local distributor.

Stray light test
Press the
icon to start the program for measuring the stray light in the instrument. In
addition to the stray light test according to DAB and Ph. Eur. at 340 nm and 370 nm with
potassium nitrate, there is an alternative stray light test available for to the UV range at 220
nm using potassium iodide. To perform a stray light test, you need the appropriate solutions
and a 10 mm quartz glass cuvette. The solutions can be mixed as follows: Dissolve 61.5 g of
potassium nitrite (p.a.) in 1 L ultrapure water and 12.0 g of potassium iodide in 1 L ultrapure
water. Select the desired method via the option button and start the automated measurement
process by pressing
. The result of the measurement will be displayed upon completion
of the test.
Via the
icon, the result of the test can be printed as a certificate or stored in the form of a
CSV- and PNG- file on an external storage medium.
If the results of the check exceed or fall below the allowed tolerances, please contact the
manufacturer or your local distributor.
6.6.1.5
Signal test
The signal test allows you to check the instrument for the signal to noise values in the visual
range at the wavelengths 345 nm, 436 nm, 540 nm, 585 nm and 700 nm. Press the
icon
to start the automated test. The test performs 50 individual measurements for each
wavelength and determines the signal scattering of the detector.
Please note: This test can take up to 15 minutes.
