5.3.4 Range Menu
The instrument operates on any full scale range from 50 to 20,000 ppb. The range is the
concentration value that equals the maximum voltage output on the rear panel of the instrument.
If the range you select is between 50 and 2000 ppb the front panel will read the concentration
anywhere from 0 to 2000 ppb regardless of the range selected. If the range selected is from 2001
to 20,000 ppb the front panel will read from 0 to 20,000 ppb. The apparently wider range of front
panel readouts is because the M200A has 2 internal hardware ranges, namely 0-2000 ppb and 0-
20,000 ppb. The analog output is scaled for the range selected, however the front panel reading
can display correct concentrations over the entire physical range.
NOTE
Only one of the following range choices can be active at any one time.
If the range is changed such that the physical range switches, the
instrument should be recalibrated. Since the gain is 10x lower on the
0-20,000 ppb range, the offsets may be a factor of 10 less also.
There are 3 range modes:
1. Single Range
2. Auto Range
3. Independent Ranges
