DTM menu path, parameters Description
<Device> / <Configuration>
<Sensor / Connection> Sensor connection type relevant for all Pt, Ni, Cu resistance thermometers
— Two-wire: sensor connection type in two-wire technology
— Three-wire: sensor connection type in three-wire technology
— Four-wire: sensor connection type in four-wire technology
<Sensor / Line resistance> Sensor line resistance relevant for all Pt, Ni, Cu resistance thermometers with a two-wire circuit
Value range: 0 ... 100 Ω
<Device> / <Configuration>
<Sensor / Reference junction> — 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
<Sensor / Reference junction
temperature>
— Relevant for external reference junction, specification of constant external reference junction
temperature
Value range: -50 … 100 °C
<Device > / <Parameterize>
<Measuring range of PV / unit> Selects the physical unit for the sensor measuring signal
Units: °C, °F, °R, K, mV, Ω, mA
<Measuring range of PV /
lower range value>
Defines the value for 4 mA (adjustable)
<Measuring range of PV /
upper range value>
Defines the value for 20 mA (adjustable)
<Current output / damping> Configurable τ 63% output signal damping value
Value range: 0 ... 100 s
<Current output / output upon
error > (overrange)
Generates a high alarm signal in the event of a sensor or device error; can be configured 20 ... 23.6 mA.
— Standard 22 mA
<Current output / output upon
error > (underrange)
Generates a low alarm signal when sensor or device errors occur; can be configured from 3.5 … 4 mA
<Device> / <Maintenance>
<Poll address / TAG>
(HART TAG)
Defines the HART TAG name
— 8 characters, alphanumeric
<Poll address / TAG>
(Address (Multidrop))
Specifies the communication type
