HTZ
Smart HART® Humidity
and Temperature Transmitter
Introduction
This is the user’s manual for Moore Industries’ HTZ
Smart HART Humidity and Temperature Transmitter.
The HTZ is a loop-powered, HART enabled,
transmitter that measures temperature and relative
humidity and calculates dew point. The HTZ consists
of two specialized components. The Humidity/
Temperature Sensor Module (HSM) has temperature
and humidity probes which can easily be removed
from the housing for replacement or service. The
second component, the Humidity/Temperature Display
Module (HDM), can remain connected to output wiring
when the sensor assembly (HSM) is removed thus
maintaining the output current loops.
The HTZ comes with optional factory trimming
(VTB) that offers higher temperature measurement
accuracy. It is applied to the sensor module (HSM)
and is independent of the display module (HDM).
For ease of viewing, the HSM and HDM may be
placed apart from each other using a dedicated 10ft
(3m) (standard), 20ft (6m) or 30ft (9m) (optional)
cable utilizing quick disconnect connectors at both
ends.
About this Manual
Wherever you see a “Note”, “Caution” or “WARNING”
pay particular attention.
WARNING - Hazardous procedure or condition that
could injure the operator.
Caution - Hazardous procedure or condition that
could damage or destroy the unit.
Note - Information that is helpful for a procedure,
condition, or operation of the unit.
Model and Serial Numbers
Moore Industries uses a system of model and serial
numbers to keep track of all of the information on
every unit it sells and services. The HSM and the
HDM each have a different, unique serial number.
If a problem occurs with your HTZ, check for a tag
listing these numbers affixed to the suspect module.
Supply the Customer Support representative with this
information when calling.
Inputs
The HTZ includes a pre-calibrated relative humidity
sensor and a fixed Pt3850 1000 ohm RTD
temperature sensor. The temperature sensor’s ohms
measurement is linearized to temperature.
Outputs
Analog Outputs
The HTZ is equipped with two analog outputs (-AO1
and -AO2). Both -AO1 and -AO2 are externally
powered (sink only) by 12-42Vdc and output a
4-20mA range with their outputs isolated from each
other.
Both are configurable to output current proportional to
any of the three available input variables (temperature,
relative humidity and dew point).
-AO1
This output powers the HTZ. It provides primary loop
power for the unit. It may be used without -AO2.
HART communications may only be utilized using
-AO1.
-AO2
This output requires its own separate loop power. It
may not be used if -AO1 is not in use.
There is no HART communication capability at this
output.

HTZ
Smart HART® Humidity
and Temperature Transmitter
Connecting the HTZ to the PC
Connect the RS-232 end of the cable to the PC’s
COM port.
Refer to Table 1 for information on the necessary
equipment.
Connecting the HTZ to the HART
Communicator
Connect the HART modem cable into the loop as
shown in Figure 3.
Once the Configuration Program is installed onto
your PC, the HTZ can be connected to equipment
to simulate input and monitor output. You can then
change the operating parameters of your unit.
No Transmitter Needed
It is not necessary to connect the transmitter to a PC
to create configuration files using the software. The
Configuration Program can be run without connecting
a transmitter, and most parameters can be set
without benefit of input from a HTZ.
This makes it easy to create a set of operating
parameters, save and download them to one or more
transmitters at a later time.
The HTZ must be connected to the PC in order
to: trim input, trim output, assign a tag, perform an
output test, receive (via download) a configuration file
and save the configuration file from the transmitter’s
memory.
Installing the Configuration Software
Refer to Table 1 for the equipment needed.
1. Insert the Moore Industries Interface Solution
Configuration Tools CD into the CD drive of
the PC. Access the CD and open the following
folders: Configuration Software and Tools/HTZ
Configuration Tools/HTZ PC Configuration
Software.
2. Double-click the installation program located
in the folder. Follow the prompts to correctly
install the program.
Configuring the HTZ
One of the benefits of the HTZ is that there are no
internal or external controls to adjust or settings to
change. All operating parameters are set using Moore
Industries’ Intelligent PC Configuration software or
a HART configurator if using HART communication
capabilities (-AO1 only).
Once these software settings are made, they are
downloaded to the instrument in the form of a Con-
figuration File and stored in the unit’s nonvolatile
memory. You can choose to save a backup copy of
the file on your PC hard drive or external media. The
HTZ communicates with the PC through a proprietary
communications cable via the PC’s serial (COM) port
or using a HART modem cable if HART communica-
tions are used.

Trimming
Trimming– Trimming increases the measurement
accuracy of your instrument by matching 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 1 Point trimming applies an offset
to the sensor reading, while 2 Point trimming applies
both an offset and a gain.
By default all three variable options are disabled. To
perform trimming each variable must be enabled
(individually). In order to enable each variable, user
must place a check mark in front of the variable that
requires trimming (See Figure 7.). This can be done
using the Trimming Menu on the Menu/Tool Bar (Refer
to Figure 6. for Trimming Menu location).

Output Test– This test may be performed in order to
check output performance and accuracy and to trim
other instruments in your setup. Your output will be a
current value, in mA, equal to the value you enter into
the text box. You can check the other devices on the
system and calibrate them to this signal.
This feature is independent of the input. If you find
that the output requires adjustment, you may perform
the Trimming function.
1. Ensure that HTZ monitoring is stopped. In the
Fix current text box, enter a value between 3.6-
23.6mA and click the Fix button.
2. Return to monitoring the HTZ. You will see the
“fixed” value in the Output Current display and
on the external multimeter.
3. Once you have finished, click Unfix.
Note:
Once you have configured all parameters, download
to the unit by selecting Download in the Transfer
dropdown menu located in the Status Bar. Or, click
the button in the Tool Bar.

Using the HART
Communicator
The HTZ can be programmed using a HART
Communicator. If your communicator is equipped
with the Device Description (DD) for your
transmitter, The HART Communicator Menu with a
Device Description section gives an overview of the
menus and instructions for programming.
The HTZ DDs are available on the HART
Foundation’s Device Driver Library Release
December 2007 and later. To determine if
your communicator has the appropriate Device
Description, follow the manufacturer’s instructions.
A list of companies will appear which, if you have
the appropriate Device Description, will include
Moore Industries HTZ.
If your communicator is not equipped with the
required Device Description, go to The HART
Communicator Menu without a Device Description
section of this manual. Some capabilities can only
be accessed if your communicator is equipped with
the proper Device Description.
If you are using a Fisher-Rosemount Model 375
HART Communicator, you may download the latest
Moore Industries DD at www.miinet.com.
If you are using a Fisher-Rosemount Model 275
HART Communicator and require the latest version
of the DD, you must either send the Communicator
to Moore Industries or the HART Foundation. To
send the instrument to Moore Industries contact
our Customer Service department for a Returned
Material Authorization (RMA).
Include Moore Industries’ configuration sheet
indicating the Device Descriptions that you require.
We will load the Device Descriptions of your choice
for a nominal charge.

and analog outputs (AO1 and AO2).
4. Setup Menu– Scroll through the Setup menu
to access configuration menus for the following
parameters: Configure Inputs, Configure Output,
Configure Dev Info and Configure Display.
A. Configure Inputs
This menu allows access to input configuration.
1 Filter– This is used to configure the input filter
which helps reduce mains-induced noise. The value
selected should match the frequency of the local AC
supply (50Hz or 60Hz).
2 EGU Selection– Specify an EGU setting using this
parameter. This affects the PV and TV. The SV has a
constant EGU read in percentage (%).
3 PV LRV / 4 PV URV– Select your primary
process variables (Temperature) lower and upper
range values, respectively. Ranges are displayed in
temperature.
5 SV LRV / 6 SV URV– Select your primary process
variables (Relative Humidity) lower and upper
range values, respectively. Ranges are displayed in
percentage.
7 TV LRV / 8 TV URV– Select your primary process
variables (Dew Point) lower and upper range values,
respectively. Ranges are displayed in temperature.
9 PV Snsr S/N– Enter your Temperature sensor’s
serial number.
10 Sensor Information– Displays the Lower Sensor
Limit (LSL), Upper Sensor Limit (USL) and the
minimum span of PV, SV and TV of the HTZ.
B. Configure Output
This menu allows you to configure the analog outputs
(-AO1 and -AO2) as well as the HART output (-AO1
only).
Analog Output
These instructions apply to both -AO1 and -AO2
configuration. By default, AO1 monitors humidity;
AO2 monitors temperature. You may select to change
this.
1 AO1 Source– Select the variable that this output
will monitor.
2 AO1 Zero– Enter your zero range output value.
This value corresponds to the unit of measure (°C, °F
or Kelvin) as selected in the EGU selection section.
Default value is 4mA.
3 AO1 Full– Enter your upper range output value.
Allowed values range from 3.6mA to 23.6mA. This
value corresponds to the unit of measure (°C, °F or
Kelvin) as selected in the EGU selection section.
Default value is 20mA.
4 AO1 Damping Rate– Damping allows you to
introduce a delay into the response for your unit
in order to stop short-lived spikes from setting off
alarms. To utilized damping, select a value between
0-30sec.
5 AO1 URV– Select a value between 3.6mA and
4.0mA as your analog output under range value (AO1
URV). If the analog output drops below the set value,
a fault will be declared. Default value is 3.8mA.
6 AO1 ORV– Select a value between 20.0mA and
23.6mA as your analog output over range value (AO1
ORV). If the analog output exceeds the set value, a
fault will be declared. Default value is 21.8mA.
7 AO1 Fail Mode– In the case of an input failure, you
have the ability to set a mode you choose to alert of
the failure. Select from:
High– Choosing this option will send the output to
a High fail mode (user-selectable between 20.0mA to
23.6mA). If selecting High fail mode, enter your value
in the following step (Fail AO1).

20 The Interface Solution Experts
HTZ
Smart HART® Humidity
and Temperature Transmitter
Low– Choosing this option will send the output to
a Low fail mode (user-selectable between 3.6mA to
4.0mA). If selecting Low fail mode, enter your value
in the following step (Fail AO1).
Hold Last– Selecting this will display the last
value present before the failure occurred.
8 Fail AO1– Select your High or Low fail mode value.
Allowed values are 20.0mA to 23.6mA for High Fail
mode and 3.6mA to 4.0mA for Low Fail mode.
9 AO1 Trim– Output trimming increases the accuracy
of your instrument by calibrating its analog output to
the device that is receiving the output. This ensures
that the instrument is being correctly interpreted.
Connect a multimeter to your HTZ output to indicate
present output reading.
Setting fld device to Output Zero will be displayed on
your communicator. Select OK if ready to proceed.
When prompted, enter the value displayed on the
multimeter into your communicator. Press Enter. If
your output matches the value on the multimeter,
select Ye s .
Next, Setting fld dev to Out Full is displayed on
your communicator. Select OK if ready to proceed.
When prompted, enter the value displayed on the
multimeter into your communicators. Press Enter.
If your output matches the value on the multimeter,
select Ye s .
10 AO1 Trim Reset– Select this in order to use
manufacturer’s trim values.
Note:
Do not perform the Output Trim Reset function
unless you want to disregard your trim values and
return to the manufacturer’s values.
Repeat Steps 1 to 10 to configure -AO2, if required.
HART Output
Use this portion of the menu to configure the Poll
Address, Burst mode and Burst Option.
1 Poll addr– The HART polling address is
represented by a number between 0 and 15. This
identifies the transmitter on the loop. In a loop with
only one HART slave on it, this address should be
0. In a multidrop loop, any of these numbers can be
used.
Note:
If the polling address is set to 0, the transmitter is
automatically set to analog mode. Multiple units on
the same bus must have different addresses.
2 Burst mode– This function allows you to achieve a
higher data rate. When enabled (On), your instrument
repeatedly transmits a data message as if it were
being commanded to do so. The Master device
receives the data more frequently than if it were
only polling the transmitter, achieving a higher data
transfer rate.
3 Burst option– Once Burst Mode is enabled, choose
which value is transmitted–PV, % range/current or
Process vars/crnt (Process variables/current).
C. Configure Dev Info
This menu allows you to configure identification
parameters for your HTZ.
1 Tag– Place a unique label that corresponds to your
instruments location or specific usage (8 characters
maximum).
2 Descriptor– Place text that is used as a description
of how the instrument is being used (16 characters,
maximum).
3 Message– Place additional information that may
be helpful in describing the instrument or its use (32
characters, maximum).
4 Date– Store a date that corresponds to specific
system function, i.e. instrument configuration date,
calibration due date, preventive maintenance
schedule, etc.
5 Final asmbly num– You may enter a number that
is used for identification purposes, and is associated
with the field device (8 characters, maximum).
6 Dev id– This is a read-only value that uniquely
identifies the field device when combined with the
manufacturer identification and device type.
7 Hardware rev– This is a read-only value that
corresponds to the revision of the electronics
hardware of the field device.
8 HSM Device ID– Displays the device identification
of the connected Humidity/Temperature Sensor
Module (HSM).
