• DEVICE ID= - This parameter sets the Modbus address ID number for the
GFM. This address is used to identify the Device when using the Modbus®
serial communications protocol. Each sensor connected to the Modbus®
network must have a unique ID number assigned. (Value Range 1 to 247)
• Clear Log Timer? – This Option is used to reset the accumulated gas flow
timer used when the log option is enabled. When set to “Yes” the timer will be
reset to 00:00:00.
• Reset Volume? – This option is used to reset the gas volume accumulator to
zero. The accumulator is used when the Log mode is set to yes. Setting this
option to “Yes” will clear the accumulated volume of gas to zero.
• Filter TC = ## - The parameter sets the filter time constant for the displayed
gas flow. Increasing this value will decrease the fluctuation in the gas flow
reading. This filter does not impact the peak readings or accumulated flow
parameters. (Value Range from 1 to 255).
• Argon Gas? - Allows the user to enable or disable Argon Gas conversion
factor. Setting this option to “No” will disable the Argon Gas conversion factor.
Setting this option to “Yes” will enable the Argon Gas conversion factor. (Status
Yes or No) Note: Disabling all Gas types (set to NO) will enable the Air
conversion factor.
• CO2 Gas? - Allows the user to enable or disable CO2 Gas conversion factor.
Setting this option to “No” will disable the CO2 Gas conversion factor. Setting
this option to “Yes” will enable the CO2 Gas conversion factor. (Status Yes or
No) Note: Disabling All Gas types (set to NO) will enable the Air conversion
factor.
• Helium Gas? - Allows the user to enable or disable Helium Gas conversion
factor. Setting this option to “No” will disable the Helium Gas conversion factor.
Setting this option to “Yes” will enable the Helium Gas conversion factor.
(Status Yes or No) Note: Disabling All Gas types (set to NO) will enable the
Air conversion factor.
• 75/25 Argon/ CO2 Gas? - Allows the user to enable or disable 75/25 Argon/
CO2 Gas conversion factor. Setting this option to “No” will disable the 75/25
Argon/ CO2 Gas conversion factor. Setting this option to “Yes” will enable the
75/25 Argon/ CO2 Gas conversion factor. (Status Yes or No) Note: Disabling
All Gas types (set to NO) will enable the Air conversion factor.
• 80/20 Argon/ CO2 Gas? - Allows the user to enable or disable 80/20 Argon/
CO2 Gas conversion factor. Setting this option to “No” will disable the 80/20
Argon/ CO2 Gas conversion factor. Setting this option to “Yes” will enable the
