6.3.2 AOM
Analog output mode. Characteristic curve of the recorder
output. See Chapter 5.3.5 Recorder output (Ao),  27.
S: AOM[,a,b]<CR>[<LF>]
R: <ACK><CR><LF>
S: <ENQ>
R: a,b<CR><LF>
6.3.3 BAU
Baud rate. Transfer rate of the RS232C interface. See
Chapter 5.3.2 Baud rate (bAud),  27.
S: BAU[,a]<CR>[<LF>]
R: <ACK><CR><LF>
S: <ENQ>
R: a<CR><LF>
NOTE:
The acknowledgement of the BAU command will al-
ready be sent with the changed transfer rate.
6.3.4 COM
Continuous mode. Continuous transmission of measure-
ments to the serial interface.
S: COM,a<CR>[<LF>]
R: <ACK><CR><LF>
The acknowledgement is immediately followed by the
continuous measurement transmission. The measure-
ments are always output in the exponential format.
R: b,±c.ccccE±cc,d,±e.eeeeE±ee,f,±g.ggggE±gg
