System control command:

Inquiry: <STX>;C;S;<CRC>;<ETX> C = control

S = start span-check

Answer: <STX>;C;S;<CRC>;<ETX> span-check will be started

Example: <STX>;C;S;19965;<ETX> 19965 = CRC16

<STX>;C;S;19965;<ETX> span-check will be started

Inquiry: <STX>;C;S;V;<CRC>;<ETX> C = control

S = span-check

V = value (= read span-check value)

Answer: <STX>;C;V;conc;<CRC>;<ETX> V = value

conc = meas. concentration in ng/m³

Example: <STX>;C;S;V;55038;<ETX> 55038 = CRC16

<STX>;C;V;1.3;14490;<ETX> 14490 = CRC16

Inquiry: <STX>;C;Z;<CRC>;<ETX> C = control

Z = start zero-check (sample volume= 1litre)

Answer: <STX>;C;Z;<CRC>;<ETX> zero-check will be started

Example: <STX>;C;Z;7675;<ETX> 7675 = CRC16

<STX>;C;Z;7675;<ETX> zero-check will be started
