•
Hexane
: Sets the mole fraction of hexane in the dry gas mixture
used when calculating the dew point temperature per ISO
18453:2006. The default value (0.00000) corresponds to the natural
gas mixture NG3.
•
High Alarm Setpoint
: Determines the concentration threshold
(ppmv or dew point C/F) above which the
Concentra High Alarm
will be triggered (see
•
I-Butane
: Sets the mole fraction of i-butane in the dry gas mixture
used when calculating the dew point temperature per ISO
18453:2006. The default value (0.00293) corresponds to the natural
gas mixture NG3.
•
I-Pentane
: Sets the mole fraction of i-pentane in the dry gas
mixture used when calculating the dew point temperature per ISO
18453:2006. The default value (0.00020) corresponds to the natural
gas mixture NG3.
•
Keypad Watchdog
: Sets the allowable time (in seconds) that the
analyzer can be on the MODE screen and the
Mode 2
(Set Parameter
Mode) password screen before automatically reverting to
Mode 1
(Normal Mode).
•
lb ConvFactor 01
: Sets a custom conversion factor when the
parameter Concentration Unit = 1 (lbs/MMscf) and this value is
greater than 0.0. The default conversion factor is used when it is
equal to 0.0.
•
Logger Rate
: Sets the number of measurements included in the
running average.
•
Low Alarm Setpoint
: Determines the concentration threshold
(ppmv or dew point C/F) below which the
Concentra Low Alarm
will
be triggered (see
•
Methane
: Sets the mole fraction of methane in the dry gas mixture
used when calculating the dew point temperature per ISO
18453:2006. The default value (0.88204) corresponds to the natural
gas mixture NG3.
•
mg ConvFactor 03
: Sets a custom conversion factor when the
parameter Concentration Unit = 3 (mg/Nm3) and this value is
greater than 0.0. The default conversion factor is used when it is
equal to 0.0.
•
Modbus Address
: Sets the analyzer address when the analyzer is
used as a Modbus slave device.
•
Modbus Mode
: Sets the communications protocol for the port
selected by the
2 Way Com Port
parameter.
•
N-Butane
: Sets the mole fraction of n-butane in the dry gas mixture
used when calculating the dew point temperature per ISO
18453:2006. The default value (0.00441) corresponds to the natural
gas mixture NG3.
