Description
• Internal: use of the internal reference junction of the transmitter when using a thermocouple / compensating cable
(relevant for all thermocouples except for type B)
• External - fixed: transfer of thermal cable / compensating cable via copper material at constant thermostat
temperature
• Without: no reference junction
Relevant for external reference junction, specification of constant external reference junction temperature
Value range: −50 to 100 °C
Selects the physical unit for the sensor measuring signal
Units: °C, °F, °R, K, mV, Ω, mA
Defines the value for 4 mA (adjustable)
Defines the value for 20 mA (adjustable)
Configurable τ 63% output signal damping value
Value range: 0 to 100 s
Generates a high alarm signal in the event of a sensor or device error; can be configured 20 to 23.6 mA
• Standard 22 mA
Generates a low alarm signal in the event of a sensor or device error; can be configured 3.5 to 4 mA
Defines the HART TAG name.
• 8 characters, alphanumeric
Specifies the communication type
• Address = 0 conforms to HART operating mode: point-to-point communication, 4 to 20 mA output signal
• Address = 1 to 15 conforms to HART multidrop operating mode output signal 3.6 mA, only the digital HART measured
values are available
• Set Trim low or lower range value > OK
Output signal correction for specified / simulated sensor LRV value to 4.000 mA set point
• Analog current measurement value input 3.5 to 4.5 mA
Output signal correction for specified / simulated sensor URV value to 20.000 mA set point
• Analog current measurement value input 19.5 to 20.5 mA
Output signal simulation corresponding to the value specified
• Value range: 3.5 to 23.6 mA
