Analyzer

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 12-18). 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.
Access the Optic Test from the DIAG Menu (refer to Figure 5-16), then press:
While the optic test is
activated, PMT should be
2000 mV ± 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.
