Measurement Modes and Device Variables
The THZ3/TDZ3 can support one or two sensor inputs. With one input it provides an output which
is proportional to the input with options for trimming, custom linearization and scaling. With two
sensor inputs there are many other measurement modes:
Single Measurement - Sensor 1 or Sensor 2 can be selectedBackup Measurement - Sensor 1 fail to Sensor 2 or Sensor 2 fail to Sensor 1. If the primary
sensor fails the secondary sensor will continue to drive the analog output without any
interruption and a HART status flag is set.
Average Measurement - This will output the average value of Sensor 1 and Sensor 2. Differential Measurement - Select from
-Differential: S1-S2
-Differential: S2-S1
-Absolute Differential: |S1-S2|
Low Select and High Select Measurements - This will output the larger or smaller
measurement of Sensor 1 or Sensor 2.
For both single sensor and two sensor inputs there are many other variables, known as Device
Variables, that are calculated from the inputs. Most HART commands use variables known as
Dynamic Variables. The Device Variables need to be assigned or ‘mapped’ to the Dynamic
Variables.

HART Broadcast Messaging (Burst Mode)
The THZ3/TDZ3 supports enhanced broadcast messaging more commonly referred to as burst
mode. When set to burst mode, the THZ3/TDZ3 will proactively send out messages instead
of waiting for the host to request them. This enables event driven communication (high, low,
deviation of signal or change in status) and/or timed communication (every x seconds) to the
host. Up to 3 different burst messages may be configured in the THZ3/TDZ
for more information on burst mode configuration
Note: When using burst mode in the THZ3/TDZ3, the host must also be configured to
communicate in burst mode.

Range Alarms (RA) can be used to detect if a Device Variable is inside or outside of an arbitrary
user specied range. Any Device Variable can be used as the source, including the RJC
Temperature, Loop Current, and Percent of Range (POR). The alarm can be set to a warning

To setup Corrosion Detection, the user captures the nominal sensor resistance value and sets

See chart below for clarication.
Selecting Warning will set a fault message on the TDZ3 display and send a HART message to
any HART Handheld or HART monitoring HOST. In addition an alert will be sent to any FDT
host that is communicating with the transmitter. Selecting Alarm will also drive the Analog output
to Fail Mode if the sensor is assigned to the PV. If the unit is in backup mode, and the primary
sensor has a corrosion alarm, the PV will switch to the backup sensor.
Broken Wire Detection
During operation, the THZ

enabled, and this feature is essential to ensure that dangerous failure of the sensor or signal
input is detected by the THZ3 and TDZ3 and consequently alarmed.

If the THZ3/TDZ

detects a broken wire or burned out sensor during operation, the transmitter
sets the output upscale or downscale to warn of trouble. The transmitter is able to identify
sensor wire(s) causing the problem and indicate the fault as a message to the HART Handheld/

Calibration
Every THZ3/TDZ3 is calibrated to our specifications prior to delivery to our customers. We
recommend that you check the calibration every year and re-calibrate only when necessary.
Please refer to the Long Term Stability Table in Section 8 of this manual. Calibration by the end
user can be performed in the field by capturing or trimming the input and/or trimming the analog
output.
Sensor trimming increases the measurement accuracy of your instrument by matching the
3
reading of its actual input to its scaling. The THZ
/TDZ3 offers the use of a trimming feature
that can be accessed using a HART Communicator, a HART Host, or an FDT Host (such as
PACTware).
Likewise, output trimming increases the measurement accuracy of the THZ
3
/TDZ3 by calibrating
its analog output to the device that is receiving the output (such as a DCS). This ensures that the
output of the THZ3/TDZ3 is being correctly interpreted.

Check the Configure Sensors settings in PACTware. This will help you to be sure to apply the
correct input with which to trim your THZ3/TDZ
and the Type is “Pt3850-1000” and Engineering Units is “degrees Celsius” then you should be
using an accurate resistance source (such as a decade box) to emulate the 3-wire, Pt 3850,

The Trim Mode can be set for One Point or Two Point. If interested in obtaining the best
accuracy at one temperature point, choose the One Point mode. The most common Trim Mode
is Two Point. This mode yields greater measurement accuracy over a temperature range by
trimming points on each side of a specic range or by trimming at your Zero and Full scale
values (as congured in the Ranging and Mapping screen). The below example outlines a Two
Point trim at the Zero and Full scale points..
Note: The current Sensor 1 Reading is -2.53° C.
Perform the following steps -
1. Set Trim Mode to “Two Point”
2. Set your input resistance to match your Sensor 1 Zero point. By example – If your Sensor 1
Zero point is 0° C the input you apply to the instrument will be 1000.00Ω.
3. Enter the Sensor 1 Zero value into the eld entitled Desired Trim Point Value. For my example
I will be entering 0 (as my range is dened as 0-100°).
4. When your reading stabilizes press the Trim Lower Point button and your Sensor 1 Reading
should now read the correct Trim Point Value (0 in this example).
5. Enter the Sensor 1 Full value into the eld entitled Desired Trim Point Value. For my example I
will be entering 100 (as my range is dened as 0-100°).
6. Set your input resistance to match your Sensor 1 Full point. By example – If your Sensor 1
Full point is 100° C the input you apply to the instrument will be 1385.00Ω.
7. When your reading stabilizes press the Trim Upper Point button and your Sensor 1 Reading
should now read the correct Trim Point Value (100 in this example).

You can then perform Sensor 2 Trim if you are using two input sensors.
Your trim values will be automatically saved to your instrument.
The output of the THZ3/TDZ3 is accurately calibrated prior to delivery to our customers.
However, you may wish to trim the instrument’s analog output to match what you are reading
on your monitoring or control system. By example: if the THZ3 is putting out 12.0mA and your
DCS is reading 11.85mA you can trim the output of the THZ
3
so that the two readings will match.
Note: trimming of the analog output will not aect the HART digital data.

The points that will be used for trimming will be the “AO Zero” and the “AO Full” that were
congured earlier. For my example these two points will be 4mA (AO Zero) and 20mA (AO Full).
In the “Output Trim” section of the Parameter screen Set Output to “Lower Output Range”. This
will set the instrument’s output to 4mA. Use your voltmeter to read the voltage drop across the
250Ω resistor and calculate the actual current going through the resistor.
Example: A voltage reading of 1.08v equates to 4.32mA (1.08V ÷ 250Ω = 4.32mA). Enter this
value in the Measured Output Current box and then push the “Trim” button.

Now, select the “Upper Output Range”. This will set the instrument’s output to 20mA. Use your
voltmeter to read the voltage drop across the 250Ω resistor and calculate the actual current
going through the resistor.
Example: A voltage reading of 4.91v equates to 19.64mA (4.91V ÷ 250Ω = 19.64mA). Enter
this value in the Measured Output Current box and then push the “Trim” button.
Now that the 2-point output trimming has been done you can test the results by entering an
output value in the “Set Current to” box. Enter 4 (for 4mA) in the box, select the “Set” button and
the instrument’s output will go to 4mA and you can check for a 1V reading across the resistor.
You can then enter 20 and check for a 5V reading across the resistor.
There is no need to press the “Apply” button as all trim changes take immediate eect.
Note: When complete BE SURE to press the “Clear” button to return control of the output back
to your THZ3/TDZ3.

Example: If your TDZ3 is congured to measure a temperature range of 50-100° F and is now on your test bench and is reading an ambient temperature of 72° then you should expect an output of 11.04mA.
If it is not feasible for you to use the actual temperature sensor for your bench test, or if your
desired temperature range is nowhere near your ambient temperature, then use a temperature

all instruments in their intended application before making any electrical connections. For
DIN rail mounted instruments, allow enough room for pivoting instruments vertically on the rail
for removal in applications involving multiple banks of units. To remove the unit from the DIN
rail you will need a simple tool such as a straight blade screwdriver. Insert the blade of the
screwdriver into the cavity at the bottom of the locking mechanism and rotate it. This will release
the locking mechanism from the DIN rail and allow you to remove the unit.

Recommended Ground Wiring Practices
Moore Industries recommends the following ground wiring practices:
• Any Moore Industries product in a metal case or housing should be grounded.
• The protective earth conductor must be connected to a system safety earth ground before
making other connections.
• All input signals to, and output signals from, Moore Industries’ products should be wired
using a shielded, twisted pair wiring technique. Shields should be connected to an earth or
safety ground.
• For the best shielding, the shield should be run all the way from the signal source to the
receiving device. (see Note below)
• The maximum length of un-shielded input and output signal wiring should be 2 inches.
Note: Some of Moore Industries’ instruments can be classified as receivers (IPT2, IPX2, etc.)
and some can be classified as transmitters (TRX, TRY, etc.) while some are both a receiver and
a transmitter (SPA2, HIM, etc). Hence, your shield ground connections should be appropriate for
the type of signal line being shielded. The shield should be grounded at the receiver and not at
the signal source.
CE Certification-related Guidelines
The grounding and wiring practices described above must be followed in order for the unit(s) to
meet the requirements set forth in EMC standard EN61326.

of custom curves which cannot be generated or imported using the HART communicator.
However, once custom curves have been saved in the unit they can be selected using the HART
Communicator.
The following Configuration Overview is applicable to both programming methods. The
remainder of this Section details programming with a HART communicator. For details of
configuring using FDT/DTM please refer to Section 5.
Configuration Overview
The following will be an overview of configuration for the THZ3/ TDZ3.
Usage of the THZ
• Single Sensor
• Dual with “identical” sensors
• Dual with diverse sensors.
When both sensors are being used, and they both produce the same units the measurements
can be combined to provide additional calculated values such as average, differential, low
select etc. The inputs can be either identical (e.g. the same exact RTD) or be different sensors,
producing the same measurement. For a full list of available measurements please see Tables
8.2 through 8.4 in Section 8.

and TDZ3 can be grouped into three general classifications:
SECTION 4
Note: To use a calculated Device Variable, both sensors’ engineering units (EGU) must be
compatible (i.e. the same, or both temperature units). If a calculated Device Variable has
different engineering units (EGU) from the sensors’ EGU, scaling will need to be used to
change the units.

a. Use the “Configure Input Types” method to select SEN1, and to have SEN2 disabled.
b. Navigate to the Sensor 1 Configuration menu, and make any additional settings as needed.
2) Assign/Map the Device Variables to the HART Variables (PV, SV etc.) The only Device
Variables available are SEN1 and RJC T. In most cases, SEN1 should be assigned to PV
(Default setting).
3) Configure the PV Range (PV URV and LRV).
4) Configure the AO’s Range, limits, and fail response.

THZ 3/ TDZ
Programmable Smart HART Temper ature Transmitter
The following additional features may also be useful:
Sensor Trimming
Sensor Trimming increases the measurement accuracy of your instrument by trimming the
reading of its actual input, to either a calibrated source or the device to which it is connected.
This verifies that the input to the transmitter is being interpreted correctly. You may trim any point
between 0% and 100% along the scale. Note that one-point trimming applies an offset to the
sensor reading, while two-point trimming applies both an offset and a gain.
Trimming can be applied to one or both sensors (SEN1 & SEN2).
Running Average Filter
This function filters the sensor input signal with a user-selected range between 1 and 16. A
higher Running Average Filter setting provides smoother output transitions; however, increases
response time. Conversely, a lower setting provides a faster response time, but may seem more
unstable.
Filter
This setting is used to configure the input filter. The filter is designed to reduce the effects of
mains induced noise. The input filter frequency value should be set to the frequency of the local
AC supply–either 50Hz or 60Hz.
Scaling
Scaling can be applied to any Device Variable including Sensor 1 and Sensor 2. It provides for a
linear transformation from the Device Variable’s units to any other engineering unit (EGU). Two
points are specified (Input minimum, Scale minimum) and (Input maximum, Scale maximum).
SECTION 4
When scaling is enabled, no unit checking is done. It is possible to convert the value from one
unit to another by configuring for unity scaling eg, (0, 0 and 100, 100). However this should be
unnecessary.
Custom Curve (Advance Settings)
The unit provides the capability to program 4 independent custom curves (CC1-4) which can be
applied to any available Device Variable to define a non-linear scaling. Each Custom Curve can
contain up to 128 pairs (X, Y) where X is the input and Y the output.
Custom Curves cannot be entered using the HART Communicator, they must be entered via the
FDT/DTM. However, once a custom curve has been saved in the unit it can be assigned and
enabled or disabled using the HART Communicator.
PV Settings
There are a few settings which apply specifically to the PV:
• PV Upper Range Value (URV) and Lower Range Value (LRV): Used to scale the PV to
the Percent of Range and Loop Current values. These settings are independent from any
other scaling settings.
• PV Damping: PV Damping allows you to introduce a delay into the response of your unit in
order to stop short-lived spikes from initiating faults and generating fault messages. The
damping time setting is the time PV takes to make a 63% change in response to a step
change.

THZ 3/ TDZ
Programmable Smart HART Temper ature Transmitter
Analog Output
The system will scale the PV from its LRV/URV (Lower Range Value / Upper Range Value) range
to the AO’s Zero/Full range. As the PV exceeds this range, the AO will continue linearly until it
reaches the AO URV (AO Under Range Value) or AO ORV (AO Over Range Value), where it
“flatlines.” At this point, the output is considered saturated, and will be limited to that value.
If the PV’s data quality goes BAD, or a system error is detected which should result in the
programmed fail response, the AO will respond as configured by either:
SECTION 4
• Fail High to 23.6 mA
• Fail Low to 3.6 mA
• Hold Last Value
• Fail to a Preset Value, configurable between 3.6 and 23.6mA
Analog Output Trimming
AO Trimming increases the accuracy of your instrument by calibrating its analog output to the
device that is receiving the output. This ensures that the instruments are matched to each other.
Display (TDZ
All dynamic and additional device variables in the transmitter can be selected for display. If none
are selected, then the unit will behave as though the PV is marked for display. A “screen” of data
includes the two main rows of characters on the display. Normally, a floating point value is shown
on the top with a text message on the bottom row. Some items require more than one screen to
be displayed. Each screen is shown for 2 seconds. If the value being displayed changes, it will
be updated while that screen is being shown.

or change in status) and/or timed communication (every x seconds) to the host.
Note: When using burst mode in the THZ3/TDZ3, the host must also be configured to
communicate in burst mode.
Up to 3 different burst messages may be configured independently in the THZ
burst message the following parameters need to be configured:

Update Periods: The Update and Maximum Update periods determine the minimum and
maximum time interval between each message. The update periods can be set to the following
values:
0.5, 1, 2, 4, 8, 16, 32, 60-3600 seconds
The actual frequency of messages sent will be determined by the update periods and trigger
mode.
If the trigger mode is set to Continuous, then the message will be sent every x seconds where x is
the Update period.
If the trigger mode is set to any other value (i.e. it is looking for a trigger) then the message will be
sent every x seconds (update period) if the trigger condition is met. If the trigger condition is not
met then a message will be sent every y seconds where y is the Maximum Update period. This
ensures that the device and host communicate regularly (once per hour if y is set to the maximum
value of 3600 seconds).

Trigger: This determines what triggers a message to be sent to the host. The trigger source value
depends on the HART command and is defined above.
There are three parameters which need to be set for the trigger - mode, level and units
Mode Level Units Description
Continuous 1.0*** Not used Messages will be sent every x seconds where x is the
Update period

SECTION 4
Window positive value set* Messages will be sent if the reading increases or
decreases by the window value
Rising any** set* Messages will be sent if the reading is above the
trigger value (High alarm)
Falling any** set* Messages will be sent if the reading is below the trigger value (Low alarm)
On Change 1.0*** Not used Used for command 48 to detect any status change
*Units must match the trigger source units. If the units do not match then trigger mode becomes inactive.
** The trigger level can be any value in the trigger source range.
*** For continuous and level modes the trigger level and units are not applicable. The level is set to 1.0 by
default.
In all cases, burst messages are sent every x seconds (Update Period) if the trigger condition is
met. If the trigger condition is not met, the update time will drop to the Maximum Update Period.
Slots 1-8: For commands 9 and 33, the Device Variables which will be sent in the message
need to be selected. By default all slots are set to ‘Not Used’. Only Slots 1-4 can be assigned for
Command 33.
If a trigger condition is set, Slot 1 must have a Device Variable assigned and this will be used as
the trigger source.
Burst message examples:
Read PV every second
Burst message settings: HART command 1:Read PV
Update period: 1 second
Maximum update period: 1 second
Trigger Mode: Continuous

Read Additional Device status every 0.5 second if there are any status changes or every
Sensor Drift Alert using Range Alarms and Sensor Corrosion Detection can also be used for
predictive diagnostics to warn of future problems.
Broken Wire Holdoff Time allows you to add an additional time delay before a sensor broken
wire is reported which provides some noise immunity and prevents false alarms caused by other
factors that may be misinterpreted as Broken Wire.
Please refer to Section 1 for more detailed information on Sensor Diagnostics.
Input Quality Alarms
The THZ3/TDZ3 also allows the user to determine how certain types of input quality issues are
handled and how they can affect the Device Variables, Dynamic Variables and AO. There are
3 different quality alarms: Measurement out of Conformance Range, Allow Limited and Allow
Dropping. See Section 6 for more information.

Input Menu:
The Setup menu allows you to access the following menus:
Sensor, and Ranging & Mapping.
Filter [60Hz]– This setting is used to configure the input filter. The filter is designed to
reduce the effects of mains induced noise. The input filter frequency value should be set to the
frequency of the local AC supply–either 50Hz or 60Hz.
PV Damping [DISABLED, 0 seconds]– PV Damping allows you to introduce a delay
(0-60 seconds) into the response of your unit in order to stop short-lived spikes from initiating
faults and generating fault messages. The damping time setting is the time PV takes to make a
63% change in response to a step change.

Input Capture– Input Capture is used to match the device input and output zero and full scale
to a known value.
Adjust input sensor to 0% value to TDZ
will set the device’s output to known 4mA value. Adjust input sensor to 100% value to
TDZ3 or THZ3 and follow the screen instructions. This will set the device’s output to a
known 20mA value.
Variable Trim– This menu allows you to view the following options Device Variable Trim,
Device Variable Trim Reset, and Display Device Variable Trim. Refer to Figure 4.15.
AO Trim– Directs you to a sub-menu. Here you can select Reset Trim, Trim Zero or Trim Full.
AO Trim Reset– Directs you to a sub-menu. Here you can select No or Yes.
Loop Test– A loop test may be performed in order to check output performance and accuracy
and to trim other instruments in the loop. Your output will be a current value, in mA, equal
to the value you input. You can check the other current devices on the loop and calibrate
them to this signal.
Input Simulation – Allows you Clear or Set a simulated Input.
S1 Corrosion Detection – This captures the nominal resistance value of Sensor 1, then
allows setting 2 threshold resistances (warning and alarm) to identify when corrosion
occurs. This applies only to Thermocouples and 3W and 4W RTDs. See section 1 for
more information on Corrosion Detection.
S2 Corrosion Detection – This captures the nominal resistance value of Sensor 2, then allows
setting 2 threshold resistances (warning and alarm) to identify when corrosion occurs.
This applies only to Thermocouples and 3W and 4W RTDs. See section 1 for more
information on Corrosion Detection.

Conguration using FDT/DTM
Software
Before reading this section on the FDT/DTM conguration, please read the Conguration
Overview at the beginning of Section 4 for general information on conguring the TDZ
This section provides information on conguring the TDZ
(an FDT frame application). For users who already have an FDT Frame Application, all the
following information is still relevant except for the PACTware installation. For more information
on FDT/DTM please refer to www.fdtgroup.org.

FDT Frame Application
Moore Industries has always provided manufacturer-specic programs to operate our eld
instruments to the full extent. TDZ
allows conguration and adjustment of any and all eld instruments ,which have a DTM. For
users who do not already have an FDT frame application, Moore Industries provides PACTware.
An FDT frame application, such as PACTware, is a PC program which interfaces with individual
software modules for instrument operation. This interface is regarded as the FDT; the individual
software modules for instrument adjustment are called DTMs (Device Type Manager) . This
conguration makes user-friendly adjustments possible because the interface for instrument
adjustment is optimally adapted to each instrument.

Furthermore, you can communicate with an FDT frame application not only via HART but also
via any standard eld bus system. Moore Industries provides a proprietary serial communication
DTM named MISP, which allows faster device conguration using our USB communication
cable. The MISP DTM will be provided in addition to the TDZ

HART Settings
The HART Settings menu provides access to the following HART settings:
See Figure 5.30 for further clarication.
Poll Address (0-63) [0] – This is the HART Polling Address, enter a number from 0-63.
Number of Response Preambles (5-20) [5]– Enter the number of Preamble Characters
(0xFF) that are sent before any HART response message. This command selects the
minimum number of preambles to be sent by a device before the start of a response
packet in the HART message. A longer preamble means slower communication. The
number of preambles may need to be manually increased for some HART hosts, if there
are missed messages or communication errors.
Tag– Place a unique label that corresponds to your instruments location or specific usage
(8 characters maximum).
Long Tag– Place a unique label that corresponds to your instruments location or specific usage
(32 characters maximum).
Descriptor– Place text that is used as a description of how the instrument is being used (16
characters, maximum).
Message– Place additional information that may be helpful in describing the instrument or its
use (32 characters,maximum).
SECTION 5
Final Assembly Number [0] – You may enter a number that is used for identification purposes,
and is associated with the field device (8 characters, maximum).
Programmed Date– This is a read-only value, displays the date this unit was programmed at
factory.
Device Id (S/N)– This is a read-only value that uniquely identifies the field device when
combined with the manufacturer identification and device type.
Hardware Revision– This is a read-only value corresponds to the revision of the electronics
hardware of the field device.
HART Revision– This is a read-only corresponds to the HART revision installed on field device.
Firmware Revision– This is a read-only value corresponds to the revision of the Firmware of
the field device.
