All three outputs can be configured either at the factory or by the user for full scale outputs of 0.1 VDC, 1VDC,
5VDC or 10VDC. Additionally A1 and A2 may be equipped with optional 0-20 mA DC current loop drivers and
configured for any current output within that range (e.g. 0-20, 2-20, 4-20, etc.). The user may also adjust the
signal level and scaling of the actual output voltage or current to match the input requirements of the recorder or
data logger (Refer to Section 6.9.4.3 and 6.9.4.5).
In its basic configuration, the A1 and A2 channels of the M100E output a signal that is proportional to the SO
2
concentration of the sample gas. Several operating modes are available which allow:
Single range mode (SNGL Mode, refer to Section 6.7.4): Both outputs are slaved together and will
represent the same concentration span (e.g. 0-50 ppm); however their electronic signal levels may be
configured for different ranges (e.g. 0-10 VDC vs. 0-.1 VDC – Refer to Section 6.9.4).
Dual range mode(DUAL mode, refer to Section 6.7.5): The two outputs can to configured for separate and
independent units of measure and measurement spans as well as separate electronic signal levels.
Auto range mode (AUTO mode, refer to Section 6.7.6) gives the analyzer the ability to automatically switch
the A1 and A2 analog outputs between two ranges (low and high) dynamically as the concentration value
fluctuates.
EXAMPLE:
A1 OUTPUT: Output Signal = 0-5 VDC representing 0-1000 ppm concentration values
A2 OUTPUT: Output Signal = 0 – 10 VDC representing 0-500 ppm concentration values.
The output, labeled A3 is special. It can be set by the user (refer to Section 6.9.10) to output any one of the
parameters accessible through the <TST TST> keys of the units Sample Display.
Output A4 is not available on the M100E Analyzer.
