The third menu option is "Duration (sec)". As the name implies, the
amount of time the gas will be read by the analyzer before performing the calcu-
lations must be entered, in seconds. A typical value for this is 120 seconds (two
minutes). It may be better to enter a longer duration if the sample system creates a
condition where the analyzer takes longer to stabilize to changes in gas concentra-
tion. To change the value, type in the desired number using the keypad, then press
Enter. To back out without changing the value, just press the Backspace (BKSP)
key.
