4.8.6. 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.
Access the Electrical Test from the DIAG Menu (refer to Figure 4-17), then press:
While the electrical test is
activated, PMT should equal:
2000 mV ± 1000 mV
