• Value of the alarm setpoint, AL–1 ####
• Out-of-range direction, HI or LO
• Defeated? Dft:Y/N (Yes/No)
• Failsafe? Fs:Y/N (Yes/No)
• Latching? Ltch:Y/N (Yes/No).
• To define the setpoint, use the < > arrow keys to move the
blinking over to AL–1 ####. Then use the
change the number. Holding down the key speeds up the
incrementing or decrementing.
• To set the other parameters use the < > arrow keys to move the

4.6 The Range Select Function
The Range function allows you to manually select the concentration range
of analysis (
In the
(concentration) limits of each Range, and select a single, fixed range to run.
CAUTION: If this is a linearized application, the new range must
be within the limits previously programmed using the
System function, if linearization is to apply through-
out the range. Furthermore, if the limits are too small
a part (approx 10 % or less) of the originally linear-
ized range, the linearization will be compromised.
In the screen, you are further allowed to select which gas applica-
tion (PREVIOUSLY defined in System function) to run.
