Safety
M211488EN-E 3
Safety
The Vaisala HMT140 Wi-Fi Data Logger delivered to you has
been tested for safety and approved as shipped from the factory.
Do not modify the unit. Improper modification can damage the
product or lead to malfunction.
Batteries
Remove batteries before shipping.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage
to electronic circuits. Vaisala products are adequately protected
against ESD for their intended use. However, it is possible to damage
the product by delivering electrostatic discharges when touching,
removing or inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages:
• Handle ESD sensitive components on a properly grounded and
protected ESD workbench.
• When this is not possible, ground yourself to the equipment chassis
before touching the boards, or ground yourself with a wrist strap
and a resistive connection cord.
• When neither of the above is possible, touch a conductive part of
the equipment chassis with your other hand before touching the
boards.
• Always hold the boards by the edges and avoid touching the
component contacts.

Introduction to the HMT140
The Vaisala HMT140 Wi-Fi Data Logger measures relative
humidity and temperature using the connected probe and
analog signals – RTD, Voltage, Current Loops and Boolean
Contacts. It is powered with three 3.6 volt DC batteries (or
an optional 9-30VDC power supply), outputs data via
wireless transmission, and comes with or without an
optional LCD display.
The HMT140 supports several different signal measurements
(channels), which are monitored in viewLinc:
• Relative Humidity (RH)
• Temperature (T)
•SwitchContact
• Voltage and Current.
Channel types are set at the factory during time of order.
Other wireless parameters can be changed at a later date
using an HMT140 Configuration Cable and HMT140 Utility
software.

Fixed or Remote Probe
The HMT140 is available either with a fixed probe directly
attached to the housing or a remote probe with different (3/
5/10 m) cable lengths. Extension cables can be easily
cascaded in order to obtain longer reach, to a maximum
length of 10 m.
Interchangeable Probe
The HMP110D HUMICAP® relative humidity probe used
in the HMT140 is fully interchangeable. You can easily
remove the probe and replace it with a new one without
having to

Introduction to the HMT140

adjust the HMT140. You have the following options when
purchasing a new probe from Vaisala:
• Order a new probe and keep your current one.
• Order a new probe and return the old one to Vaisala
(replacement probe).
Note: Only probes that have a compatible digital out-
put (VDIGI mode) can be used with the
HMT140. Compatible probes have the letter "V"
as the first letter in their order code. The order
code is written on the probe.
Optional Display
The HMT140 is also available with an optional graphical
128x64 pixel resolution LCD display. The display shows the
measurement results of selected parameters in selected units
(defined at the time of ordering). The parameters are
displayed simultaneously as two separate rows on the
display.
HMT140 Components

Installation Kit
The HMT140 is typically installed mounted on the wall with
up to four screws (not included). See Figure 2 on page 15.
For duct mounting, Duct Installation Kits are available as
accessories. See Options and Accessories, on page 9.
To help you position the screws correctly, use the Drilling
Template, available inside the back cover of the Quick Guide.
HMT140 Utility and Configuration Cable
To connect an HMT140 to your network, you will need to
install the HMT140 Utility software and connect the
HMT140 to your PC with the configuration cable (see,
Connecting to your Network, on page 24).

CHAPTER 3
INSTALLATION
This chapter provides the information you need to:
• Mount the HMT140 on a wall or duct
•ConnecttheHMT140to your network
• Review optional mounting accessories

Mounting
14 VAISALA
Mounting
Depending on your installation requirements, you may wish
to complete the network configuration and setup prior to
mounting (see, Chapter 4 Setup and Operation). Note that
you can complete the configuration and setup procedures
after mounting with a portable PC.
Note: To connect the HMT140 to your network
and view HMT140 data using viewLinc, you
require HMT140 Utility software and an
HMT140 Configuration Cable (shipped with
viewLinc).
Wall Mounting
To mount the HMT140 on a wall:
Note: If mounting against a metal surface, be sure to
keep a minimum of 2 mm between the metal and
the back of the HMT140 to ensure an uninter-
rupted radio signal.
1Open the HMT140 cover. Use your thumb to press and
hold the release tab located between the two glands (see
Figure 9 on page 19), then pull the cover out and up with
your other hand.
2Make sure that the HMT140 is correctly aligned and
attach it directly to the wall with up to four screws (not
included in the package).
• Select the size and type of the fastening screws
according to the wall material (for example, wood or
stone). The diameter of the fastening screws is
typically between 3.5 and 4 mm.

Mounting
M211488EN-E 15
Figure 2: Mounting Diagram
Note: It is strongly recommended that you use all four
screws; however, the HMT140 enclosure fasten-
ing holes are initially covered with a thin plastic
membrane, so less than four screws could be also
be used without sacrificing the ingress protection
(IP) class of the enclosure.
Duct Installation
The duct installation kit includes a plastic pipe with a flange
(Vaisala part#: 215619).
To install the HMP110D probe with the duct installation kit,
drill ahole into the duct wall, assemble theprobe to the duct
installation kit, slide the probe head through the hole, and
attach the flange to the duct wall with four screws.
