6.9.6. Electrical Test
The electrical test function creates a current, which substitutes the PMT signal, and feeds it into the
preamplifier board. This signal is generated by circuitry on the pre-amplifier board itself and tests
the filtering and amplification functions of that assembly along with the A/D converter on the
motherboard. It does not test the PMT itself. The electrical test should produce a PMT signal of
about 2000 ±1000 mV.
To activate the electrical test press the following keys.
