Logger Rate
The Logger Rate parameter sets the number of measurements included in the
running average. The display and the current loop output will each have a value
representing the running average of the concentration over a number of
measurements equal to Logger Rate . Enter the required value.
Low Alarm Setpoint
The Low Alarm Setpoint parameter determines the concentration threshold
below which the Concentra Low Alarm fault will be triggered (refer to
“Alarms” on page 2-42). The value entered is compared to the moving
average over the number of measurement points set by the Logger Rate . The
setpoint must have a value less than the minimum range of the analyzer or
minimum dew point to be turned off.
Modbus Address
The Modbus Address parameter sets the analyzer address for when the
analyzer is used as a Modbus device. Addresses from 1 to 250 can be entered.
Modbus Mode
The Modbus Mode parameter sets the communications protocol for the port
selected in the 2 Way Com Port parameter. There are three choices: 0 for
turning the Modbus capabilities off and defaulting to generic serial output as
described in “Receiving Serial Data (Customer Port Output)” on page 3-1
(the ports not designated for two-way communications will also output the
generic serial output); 1 for enabling the analyzer to respond to Gould Modbus
