Instrument Configuration
This webpage allows the user to make changes to the sensor’s configuration. .
Set Date/Time: This option, when pressed, will sync the current time of the main board
to the computer on which the web interface is running.
Web Access Code: This is the code that allows the user to have access to some of the
webpages in which critical setting changes can be made.
Min. Gas%: This reading indicates the point at which anything below will be read as zero
for internal calculations.
N2/NH3/DA/H2 Flow: Gas flow values can be manually entered into these fields for
nitriding calculations such as nitriding potential (Kn), percent dissociation (%DA),
percent ammonia (%NH3), and/or super Kn. These calculations are displayed on the
Main webpage when selected on the SSI Configuration webpage.
CO2 Pres.: This is a special calculation for specific applications. The input should be set
to 0 as a default, unless specifically discussed with SSi.
Sup Neg: (Suppress Negative) When activated, any negative readings will be treated as
zero.

Output Configuration
The Output Configuration options allow 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 or a calculated
value based on the gas measurements. The options include:
H2: Percent hydrogen reading from the sensor.
