4.6.5. 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:
