Output Configuration
The Output Configuration options allows the user to set up an analog output milliamp signal
from the SGSM to a chart recorder or other device for recording or controlling another process.
There are two outputs that can be set up for the gas being measured (the options are
External
&
NDIR Gas ).
When “NDIR Gas” is selected, the user can choose a 0 – 20 mA or 4 – 20 mA output range for
the gas percentage calibration range.
The “External” option is for special cases where an additional analog output is required from an
external source. Contact SSi for additional details about this option.
The Output Configuration screen allows you to adjust output parameters for loops 1 and 2.
For each loop, the following parameters can be adjusted:

Source: A selected source: External or NDIR Gas.
