6.13.7.3. 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.
