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 mADC 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 (See Sections 4.6.3.3 and 4.6.3.5).
In its basic configuration, the A1 and A2 channels of the T101 output a signal that is
proportional to the H S concentration of the sample gas. Several operating modes are

available which allow them to be slaved together (SNGL Mode, see Section 4.4.4.4 or
