Optic Test - Teledyne 100E Instruction Manual

Model 100E Instruction Manual

6.7.5. 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 (Fig. 10-15). 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 make sure 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. To activate the electrical test
press the following key sequence.

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
