Dark Current Test
The dark- current test measures the leakage current from the sample and
reference circuits. The test is used to check for defective sample or
reference diodes or ADC circuits which may cause non- linearity or
excessive baseline noise. During the test, the shutter is moved into the
light path. Next, the leakage current from both diodes is measured.
