text colour and comments are in
GREEN
text colour.
5.1.1 Setup before measurement
This describes the interface commands used for setting up the Gas Monitor
before a measurement. The example sets up all the five filters for
measuring.
SE L_U,U_METER
set gas monitor display unit for length
SE H_U,U_TDEW
set gas monitor display unit for humidity

set gas monitor display unit for pressure
SE T_U,U_CE
set gas monitor display unit for temperature
SE C_U,U_PPM
set gas monitor display unit for concentration
SE C_C,Y
enable cross compensation
SE W_C,Y
enable water compensation
SE C_S,Y
enable cross compensation
SE N_T,20.0
set normalization temperature
SE CL,"10:08"
set time
