Service Transducer Block
This block is primarily used to setup, configure and diagnose the ST100 from a remote location via a FF configurator, or a system monitor. Variables

set or changed by this block will affect all sensors, when rights are authorized. Write access is authorized through the “PC Configurator” applica-

tion from a computer connected to the ST100 through its USB or Ethernet service ports.
This block provides access to the ST100 basic setup parameters; some are read and write others are read only. This block can be used to review

factory set calibration limits and settings of other process variables, like the Plenum size, and to read and write the engineering units of the

process variables. In addition, this block can be used to view process data from individual sensor elements in a multi-point system.
This block does not have an output, and it does not make any data available to other blocks

Factory Calibration Limits
MAX_CAL_FLOW
parameter
This parameter presents the value of the maximum calibrated flow limit that was set by the factory, for the active flow classification, and

cal group.

MIN_CAL_FLOW parameter
This parameter presents the value of the minimum calibrated flow limit that was set by the factory, for the active flow classification, and cal

group.

MAX_CAL_TEMP parameter
This parameter presents the value of the maximum calibrated temperature limit that was set by the factory during the factory calibration

process.

MIN_CAL_TEMP parameter
This parameter presents the value of the minimum calibrated temperature limit that was set by the factory during the calibration process.

MAX_CAL_PRES parameter
This parameter presents the value of the maximum calibrated pressure limit that was set by the factory during the factory calibration pro-

cess. This parameter applies to instruments that have a pressure sensor.

MIN_CAL_PRES parameter
This parameter presents the value of the minimum calibrated pressure limit that was set by the factory. This parameter applies to instru-

ments that have a pressure sensor.

Process Engineering Units
FLOW_ENG_UNITS
parameter
This parameter presents the engineering units associated with the process flow variable.

TOTALIZER_ENG_UNITS parameter
This parameter presents the engineering units associated with the process Totalizer variable. The Totalizer applies only to flow units that

are volumetric or mass, and it is a parameter that can be turned off.

PLENUM_SIZE_VALUE_DIAMETER parameter
This parameter presents the engineering units associated with the pipe size diameter parameter, or the width parameter of the duct in

which the ST100 Flowmeter is installed.

PLENUM_SIZE_VALUE_HEIGHT parameter
This parameter presents the engineering units associated with the duct in which the ST100 Flowmeter is installed.

PRESSURE_ENG_UNITS parameter
This parameter presents the engineering units associated with the process Pressure variable. This parameter applies to instruments that

have a pressure sensor, and may not be active in all instruments.
