It is important to note that when you enter the Quick Select
mode for the H2S cell, you cannot change the flow rate of the
instrument. The Cal 2000 instrument will automatically vary
the flow rate to acheive the different ppm concentrations of
H2S.
Once you have entered the Quick Select mode for the Cal
2000, you can only adjust the ppm concentration in fixed 10
ppm increments, between 20 ppm and 100 ppm.
