Dark Current Test - Agilent Technologies 1200 Infinity Series User Manual

Dark Current Test

The dark-current test measures the leakage current from each diode. The test
is used to check for leaking diodes which may cause non-linearity at specific
wavelengths. During the test, the slit assembly moves to the dark position,
cutting off all light falling onto the diode array. Next, the leakage current from
each diode is measured, and displayed graphically. The leakage current
(represented in counts) for each diode should fall within the limits.
When In case of problem.
1 Run the Dark Current Test with the recommended user interface (for further
