AP05:3 Analogue settings
Valid for version 1 and 2 of circuit board AP05
Analogue settings, version 1 of circuit board AP05.
All analogue signals from AP05 to the processor board AP04 are related to a
regulated 5V supply from AP04 (UREF_POT +5V). This voltage has an accuracy
of ±1%. All boards, including spare parts, are adjusted at the factory.
The potentiometers on the front panel are described in the instr uctions on page
72, which also shows their locations.
