3-74 49iQ Instruction Manual
The Range Setting screen defines the concentration range of the analog
outputs. For example, an O
output to concentrations between 0 and 500 ppb.
The screen shows the current O
single, dual, and auto range modes. The only difference between the
screens are the words "High" or "Low" displayed to indicate which range is
displayed. For more information about the dual and auto range modes, see
"Range Mode Selection" on page 3-72. Pressing Range Setting, High
Range Setting or Low Range Setting, brings up a numeric keypad whereby
the user can select a range.
Settable ranges according to unit selection include:
ppb 50200,000 ppb
ppm 0.05200 ppm
% 0.0000050.02 %
μg/m 3 100400,000 μg/m
