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 o󰀨ers 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 1m
(3ft), 3m (10ft), 6m (20ft), 9m (30ft), 15m (49ft), 25m
(82ft) or 30m (98ft) (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 di󰀨erent, unique serial number.
If a problem occurs with your HTZ, check for a tag
listing these numbers a󰀩xed 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 xed Pt3850 1000 ohm RTD
temperature sensor. The temperature sensor’s ohms
measurement is linearized to temperature.
-FLEX120
The -FLEX120 exible sensor cable extension
option provides a exible extension for your humidity
and temperature sensors. Attached at the sensor
connection head, it extends the sensor placement
to locations as far as 120 inches (3.48 meters)
away. This gives you access to locations where
the connection head can’t be placed such as hung
ceilings, and allows the sensors to be suspended
to obtain readings mid-room at lower than ceiling
heights. Being exible, the sensors won’t break when
bumped during facility changes.
Note - The FLEX120 120-inch exible sensor
extension requires -CL3.75 and -GRIP1 with LH4P
housing.
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 congurable 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.

EW = 10^ (0.66077 + (7.5 * T / (237.3 + T) ) )
EW_RH = EW * RH / 100
Dew Point (Dp)= ( (0.66077 – log10 (EW_RH) ) * 237.3) / (log10 (EW_RH) – 8.16077)
This is the saturation vapor pressure over water
Multiply EW with RH
Equation 1. Dew Point Calculation
* High accuracy relative humidity measurements are achieved within a RH range of 33-75% using the trimming feature of Moore Industries’ Intelligent PC
Conguration Software with the RH sensor calibrated against a controlled RH environment (See the -VTRH option under “Sensor Length/Calibration” in Ordering
Information). High accuracy temperature measurements are achieved using the trimming feature of the Intelligent PC Conguration Software with the temperature
sensor immersed in a temperature calibration bath (Sensor-to-Transmitter matching factory calibration; See the -VTB option under “Sensor Length/Calibration”
in Ordering Information). High accuracy dew point measurements are achieved using the trimming feature of the Intelligent PC Conguration Software at 25°C,
between 40-90% RH. Stated accuracies do not include ambient temperature e󰀨ects.

HTZ
Smart HART® Humidity
and Temperature Transmitter
Connecting the HTZ to the PC
Connect the RS-232 cable to the PC’s COM port or
Optional USB Cable to the USB port.
Refer to Table 1 for necessary equipment.
Connecting the HTZ to the HART
Communicator
Connect the HART Communicator or HART Modem to
the HTZ’s Analog Output 1 (AO1) as shown in Figure
5.
Once the Conguration Program is installed onto your
PC, you now have the ability to program the HTZ or
while connected, monitor the HTZ’s input and output
parameters in real time.
No Transmitter Needed
It is not necessary to connect the transmitter to a PC
to create conguration les using the software. The
Conguration Program can be run without connecting
a transmitter, and most parameters can be set
without the connection of an HTZ.
This makes it easy to create a conguration le
o󰀪ine, 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 conguration le and
save the conguration le from the transmitter’s
memory.
Installing the Conguration Software
Refer to Table 1 for necessary equipment.
1. Download the latest conguration le from the
website http://www.miinet.com/
2. Or insert the Moore Industries Interface
Solution Conguration Tools CD into the CD
drive of the PC. Access the CD and open
the following folders: Conguration Software
and Tools/HTZ Conguration Tools/HTZ PC
Conguration Software.
3. Double-click the installation program located
in the folder. Follow the prompts to correctly
install the program.
Conguring the HTZ
One of the benets 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 Conguration software or
a HART congurator 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-
guration File and stored in the unit’s nonvolatile
memory. You can choose to save a backup copy of
the le 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.

Or, click the button in the Tool Bar.
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 veries 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 o󰀨set
to the sensor reading, while 2 Point trimming applies
both an o󰀨set 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. This can be done using the
Trimming Menu on the Menu/Tool Bar (Refer to Figure
9 for Trimming Menu location).

Fail Mode– In the case of an input failure, you have
the ability to set a mode you choose to alert of the
failure.
High – Choosing this option will send the output
to a High fail mode (user-selectable
between 20.0mA to 23.6mA).
Low – Choosing this option will send the output
to a Low fail mode (user-selectable
between 3.6mA to 4.0mA).
Hold Last –This will display the last value present
before the failure.
The Sensor Error Value box displays your selected
value.
Damping– Output Damping allows you to introduce a
delay (0-30sec) into the response of your unit in order
to stop short-lived spikes from setting o󰀨 alarms.
1. Select Enabled if you choose to use Damping.
2. Enter your damping time into the associated
text box.
Output Current – Displays the value present at your
output when the PC Conguration Software is in
Monitor mode.
Trimming– 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.
1. Click the Lower button to trim the Lower Output
Range.
2. To “ne tune” trimmed values, place the value
read on the external multimeter, connected to
your instrument for trimming, in the Measured
Loop Current text box and click Trim.
3. Click the Upper button and repeat Step 2 to
trim the Upper Output Range.
4. Once you have performed your output
trimming, click Unx.
Note: Do not click the Reset button in the Trimming
menu unless you want to disregard your trimmed
values and return to the manufacturer’s trim values.
Analog Output
Steps discussed in this section apply to both the
Analog Output 1 and Analog Output 2 tabs of the HTZ
PC Conguration Software.
Source– This user-congurable parameter denes
the variable that the analog output will monitor. By
default, AO1 monitors the humidity value; AO2
monitors temperature.
Source Range– These values reect the Lower
Range and Upper Range values as displayed in the
Sensor Range section of the Input tab.
Output Range– Sets the analog output range limits.
Default value is 4-20mA.
1. Enter your low and high limit values into the
text boxes.
2. In the Under Range Min. Value box, enter the
lowest value your output can reach (typically
between the Fail Low and the Zero % output
value). The allowed limits are 3.6mA to 4.0mA.
Default is 3.8mA.
3. In the Over Range Max. Value box, enter the
highest value your output can reach (typically
between the Fail High and the 100% output
value). The allowed limits are 20.0mA to
23.6mA. Default is 21.8mA.

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 nd
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
“xed” value in the Output Current display and
on the external multimeter.
3. Once you have nished, click Unx.
Note:
Once you have congured 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’ conguration sheet
indicating the Device Descriptions that you require.
We will load the Device Descriptions of your choice
for a nominal charge.
For installation of the latest device description
through the HART Foundation, contact the HART
Communication Foundation at the location below:
HART Communication Foundation
9390 Research Blvd., Suite I-350
Austin, TX 78759-6540
USA
Phone: [phone]
Fax: [phone]
www.hartcomm.org
Ensure that you contact the HART Foundation
to determine their requirements in sending the
instrument to their facility.
Programming When a Device
Description is Available
With the transmitter connected, apply power and
turn on the communicator. After a brief self-test, the
communicator will show the main menu and identify
the unit as an HTZ.
This section contains the instructions for programming
the transmitter using a HART Communicator that
has been programmed with a HART Device
Description. If your communicator does not have the
appropriate Device Description, skip to The HART
Communicator Menu without a Device Description
section of this manual.
Figure 14 shows an overview of the programming
menus for the conguration process.
