Assignment of terminal connections for DIN rail device
To check the output current, an amperemeter (DC measurement) can be connected between the "Test" and "-" terminals.
To operate the device via the HART® protocol (terminals 1 and 2), a minimum load of 250
Ω is required in the signal circuit.
NOTICE
ESD - electrostatic discharge. Protect the terminals from electrostatic discharge.
Failure to observe this may result in destruction or malfunction of parts of the
electronics.

Terminal assignment of the sensor connections→  8,  17.
NOTICE
When connecting 2 sensors ensure that there is no galvanic connection between the
sensors (e.g. caused by sensor elements that are not isolated from the thermowell).
The resulting equalizing currents distort the measurements considerably.
‣ The sensors must remain galvanically isolated from one another by connecting each
sensor separately to a transmitter. The transmitter provides sufficient galvanic isolation
(> 2 kV AC) between the input and output.
The following connection combinations are possible when both sensor inputs are assigned:

Supported HART® commands
The HART® protocol enables the transfer of measuring data and device data between
the HART® master and the field device for configuration and diagnostics purposes.
HART® masters such as the handheld terminal or PC-based operating programs (e.g.
FieldCare) need device description files (DD, DTM) which are used to access all the
information in a HART® device. This information is transmitted exclusively via
"commands".
There are three different types of command
• Universal commands:
All HART® devices support and use universal commands. These are associated with the
following functionalities for example:
– Recognition of HART® devices
– Reading digital measured values
• Common practice commands:
Common practice commands offer functions which are supported and can be executed by
many but not all field devices.
• Device-specific commands:
These commands allow access to device-specific functions which are not HART®
standard. Such commands access individual field device information, among other
things.

(hardware write protection), →  26 or
• deactivate the software write protection via the operating tool. See the description for
the 'Define device write protection' parameter. →  84
When hardware write protection is active (write protection switch on the back of the
display to the "ON" position), write protection cannot be disabled via the operating
tool. Hardware write protection must always be disabled before software write
protection can be enabled or disabled.

Sensor adjustment
Sensor transmitter matching
RTD sensors are one of the most linear temperature measuring elements. Nevertheless,
the output must be linearized. To significantly improve temperature measurement
accuracy, the device allows the use of two methods:
50
Endress+Hauser
iTEMP TMT82
Technical data
• Callendar-Van-Dusen coefficients (Pt100 resistance thermometer)
The Callendar-Van-Dusen equation is described as:
RT = R0[1+AT+BT²+C(T-100)T³]
The coefficients A, B and C are used to match the sensor (platinum) and transmitter in
order to improve the accuracy of the measuring system. The coefficients for a standard
sensor are specified in IEC 751. If no standard sensor is available or if greater accuracy is
required, the coefficients for each sensor can be determined specifically with the aid of
sensor calibration.
• Linearization for copper/nickel resistance thermometers (RTD)
The polynomial equation for copper/nickel is as follows:
RT = R0(1+AT+BT²)
The coefficients A and B are used for the linearization of nickel or copper resistance
thermometers (RTD). The exact values of the coefficients derive from the calibration
data and are specific to each sensor. The sensor-specific coefficients are then sent to the
transmitter.
Sensor transmitter matching using one of the methods explained above significantly
improves the temperature measurement accuracy of the entire system. This is because the
transmitter uses the specific data pertaining to the connected sensor to calculate the
measured temperature, instead of using the standardized sensor curve data.
1-point adjustment (offset)
Shifts the sensor value
2-point adjustment (sensor trimming)
Correction (slope and offset) of the measured sensor value at transmitter input
Current output adjustment
Correction of 4 or 20 mA current output value (not possible in SIL mode)
Operating influences

Corrosion monitoring
Sensor connection cable corrosion can lead to false measured value readings. Therefore
the unit offers the possibility of recognizing any corrosion before a measured value is
affected. Corrosion monitoring is only possible for RTDs with a 4-wire connection and
thermocouples.
Drift/difference mode
If two sensors are connected and the measured values differ by a specified value, a status
signal is generated as a diagnostic event. The drift/difference monitoring function can be
used to verify the correctness of the measured values and for mutual monitoring of the
connected sensors. Drift/difference monitoring is enabled with the Drift/difference mode
parameter. A distinction is made between two specific modes. If the In band option is
selected (ISV1-SV2I < drift/difference set point), a status message is issued if the value
drops below the set point, or if the value exceeds the set point if the Out band (drift)
option is selected (ISV1-SV2I > drift/difference set point).
Procedure for configuring the drift/difference mode
1. Start

2. For drift/difference monitoring, select Out band for drift detection and In band for difference monitoring.

Sensor error adjustment (sensor trimming)
Sensor trimming is used to adapt the actual sensor signal to the linearization of the
selected sensor type stored in the transmitter. Compared to sensor transmitter matching,
sensor trimming only takes place at the start and end value and does not achieve the same
level of accuracy.
Sensor trimming does not adapt the measuring range. It is used to adapt the sensor
signal to the linearization stored in the transmitter.
Procedure
1. Start
ß
2. Set the Sensor trimming parameter to the Customer-specific setting.

3. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature. A
temperature which is close to the set start of the measuring range is recommended.
ß
4. Enter the reference temperature for the value at the start of the measuring range for the Sensor trimming
lower value parameter. Based on the difference between the specified reference temperature and the
temperature actually measured at the input, the transmitter internally calculates a correction factor which is
now used to linearize the input signal.
ß
5. Using a water/oil bath, bring the sensor connected to the transmitter to a known and stable temperature
close to the set end of the measuring range.
