Dark Current Test

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.
