During the instruments set up the pH value this is an external measured precision reference barometer value is entered via service routines The characteristic values S PH input value and MWH ADC value are stored in EEPROM when the analyzer is put into operation and must be resaved when a board and or a component replacement is made There are additionally 3 analog sensor connections provided at the C2 Connector Board which are actually not used One sensor pressure sensor can optionally be connected on the COBA Control Board The operational amplifier I44 is intended for connection to a pressure sensor The signal SENSE GAS is connected with the wC ADC channel 14 The selection of the analog signals to be measured are performed by the 8 channel multiplexer 4051 122 The multiplexer is supplied with 5 V analog to allow switching of the analog signals The channel switching results from three control lines MUX 0 MUX 1 MUX 2 The output of MUX I22 3 is connected to the resistor R31 of the filter In order to avoid measurement problems external switching peaks from inductive loads power noise an active low pass filter simplified Bessel filter third order with a limit frequency of 30 Hz is used Therefore a time constant rise of the signal of about 60 ms results when level variation occurs In order to make use of the accuracy of the ADC the measurement of the analog signal starts 120 milliseconds after a multiplexer c
