(*) Channel 04 = The « -15V signal » of the multiplexer is an indicating measurement, but not a direct
measurement of the – 15V voltage really present on the board and which can be measured with a
voltmeter. The tolerance on the real – 15 V is ± 50 mV.
(**) Channel 05 = 600 V effective only when the (GM) counter is supplied.
