5.9.4. OPTIC TEST
The optic test function tests the response of the PMT sensor by turning on an LED
located in the cooling block of the PMT (refer to Figure 13-18). The analyzer uses the
light emitted from the LED to test its photo-electronic subsystem, including the PMT
and the current to voltage converter on the pre-amplifier board. To ensure that the
analyzer measures only the light coming from the LED, the analyzer should be supplied
with zero air. The optic test should produce a PMT signal of about 2000±1000 mV.

This is a coarse test for functionality and not an accurate calibration tool.
The resulting PMT signal can vary significantly over time and also
changes with low-level calibration.
