5.3. SETUP – DAS: INTERNAL DATA ACQUISITION SYSTEM
Use the SETUP>DAS menu to capture and record data. Refer to Section 0 for
configuration and operation details.
5.4. SETUP – RNGE: ANALOG OUTPUT REPORTING RANGE
CONFIGURATION
Use the SETUP>RNGE menu to configure output reporting ranges, including scaled
reporting ranges to handle data resolution challenges. This section describes
configuration for Single, Dual, and Auto Range modes.
5.4.1. AVAILABLE ANALOG OUTPUT SIGNALS
The analyzer has three active analog output signals, accessible through a connector on
the rear panel.

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 T100 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.
