Diode Array Detector (DAD)
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 (see Figure 53 on page 176).
The leakage current (represented in counts) for each diode should fall within
the limits (red bands) shown in the plot (see Figure 53 on page 176).
