Introduction
Thank you for choosing an HWM data logger(s), we trust it will provide you
with many years of service.
The individual configuration of your logger(s) may differ slightly from the
detailed descriptions that follow, but any additional setup information that you
need, should be available from our website.
Unpacking
As you unpack your new logger, please confirm that you have the following
parts required to install the equipment. If there are any omissions, please
contact our sales team to rectify or supply the missing parts.

Installing the software
1. Insert the CD-ROM supplied into your CD drive.
(If your PC does not have a CD drive, then either copy the files from
the CD-ROM onto a memory stick, or download and run the installation
file from the HWM website at www.hwmglobal.com)
NOTE: If you use proprietary archiving software, such as WinZip or 7zip,
please ensure that you extract the files to a temporary folder using the
automatic extraction buttons that maintain the original folder structure.
2. Ensure you have system administration rights for your computer, ask
your IT department if you are unsure.
3. If the installation does not start automatically, locate and run the file
“setup.exe” (in the IDTInstall/IDT folder), which installs the program
and the necessary USB drivers for the device.
4. Follow the on screen installation instructions to complete the install of
the IDT.
Should the automatic installation fail, please check with your system
administrator that you have sufficient rights to install the driver or try
installing the drivers manually.
You may be required to update Microsoft.Net; the install file is included
with the IDT setup files for your convenience.

5
Installation and site hardware Diagnostics Tool (IDT)
Once you have installed the IDT, connect the USB IR Reader to your PC.
The first time you connect your IR Reader to a new USB port, Windows will
configure the driver, wait until this process is completed before proceeding.
Position the reader head on the logger as shown below:
Take care to position the
head over raised ring area
around the window. The
reader head will hold onto the
logger by magnets in the ring
around the window and this
helps with positioning.
Reading the logger
1. Run the “IDT” program.
2. The main window will appear of which the main items are:-
Toolbar Software version no.
User Mode
Configuration mode
selection tabs
Main setup window
Function
buttons

6
3. Now click the <<Read Logger>> button to load the current logger
settings into the setup window.
4. The IDT will now download the current settings from the logger.
At this point the IDT will check to see if there is a more up-to-
date version of the logger firmware available on your PC, if so,
you will see the message “Update Available”. Click <<Yes>> to
update the logger, the process will take approximately 2
minutes, however the logger will be restarted so you may wish
to transfer any logged data first, in which case click <<No>>.
The IDT checks the firmware version each time you read it.
5. Once all the settings have been loaded you will see this message,
Click <<OK>> to start configuring your logger.

7
Configuring the logger
1. You will now see the main setup menu
(expanded for illustration purposes)
The menu is structured in sections for
easy setup and changes content
depending on type of logger connected
and software mode:
i) Logger Details including ID
and SIM card phone number
ii) Logger start time and data capture interval
(days or time of measurement period)
iii) Logger channel configuration including
calibration factors
(see appendix for info)
iv) Logger recorded meter readings
v) Cellular data service provider settings
vi) Data call settings
Data Destination details, the server address
for the UDP data
vii) Backup call in timing details in case of
main call failure or external battery exhaustion
and SMS message destination number
viii) Alarm configuration
(Advanced mode only)
Final Setup button and
logger time zone selection
Main function buttons
Note that the IDT is regularly updated so may not match the picture above

8
2. Now you can enter the configuration you require for each section
i. Logger –enter the site ID that you wish for the logger, e.g.
Postal/ZIP code up to 7 alpha-numeric characters and the
telephone number associated with the SIM card.
If you ordered a SIM with the logger, this will have been
programmed already for you, otherwise enter the number from
your service provider in international format (e.g. +44…)
ii. Logging Parameters –Accept the default start time or enter
your own. Default start time is in the past so the logger will begin
recording immediately. You can delay this start time by selecting
one from the calendar or enter the time directly from your
number keypad. Set your log interval by ticking the “24 hour”
box or enter a shorter time in the time box. (Default is 15mins)
iii. Logging Channels –Here you can configure your connections
and what data you wish to see.
From the dropdown box select the Type of data
to appear on Channel 1. This will depend on
your individual order, but you may have a
selection like that show here. Click “-----” if you
do not wish to use that channel.
Next choose what mode of collation you wish
Avg = average reading over the log interval
Min/Max = Min/Max values measured over the log
interval
Spot = The value at the log interval
State= the state of the switch at the log interval
Now, if required, enter the scaling factor for the chosen
Type of logger input, click in the box and enter the
multiplication factor you require. See appendix for info.
iv. Meter Readings –If you wish the
meter reading to be sent through to
HWMonline, enter the current value
in the box(s). This needs to be
configured on site as the timing is important, however it can be
corrected later via HWMOnline.
v. APN –If you have ordered a data pack from HWM you can
leave this setting alone (as below) as your logger will have been
preconfigured by HWM.

9
If you have ordered your data service & SIM card, then you will
need to separately configure your service. HWM recommends
that you allow the GPRS test utility to search for these settings
automatically, however if you wish to enter them manually, click
the button beside “Use the following settings”
You can now enter your
data service provider’s
details into the appropriate
boxes.
Alternatively select your
network from the drop
down list of presets
vi. Time(s) Data sent –Here you specify the Call Out requirement
for the logger. There are 2 modes available, SMS and UDP.
SMS is a one way unacknowledged data transfer service using
the common text messaging service. UDP is a true 2 way
confirmed data transfer process via the internet over a GPRS
connection. Both have advantages, however HWM recommends
UDP wherever possible as this offers the most secure method of
data transfer.
Switch on the Call out by
selecting “1” in the Address
selector, then choose UDP or
SMS from the Type selector.
vii. Call Addresses –These will usually have been entered at the
factory and should not be adjusted,
however if you have your own data
server, then you can enter either the
telephone number for your receiving
modem, or the UDP address & port no
for where the logger is to send its data.
The fall back times specified here instruct the
logger what to do in the event of the primary
Call Out requirement not being met. This can be
for 2 reasons:-
a. If a connected external battery goes flat, the logger will
default from the normal call out requirement to a 2 times
per day routine. The times of these calls are specified by
both Fall back 1 & 2.
b. If a GPRS data call cannot be completed due to non-
availability of a GPRS service, then the logger will try to
send an SMS message at the Fall back 1 time.

10
Now choose your Call out mode, this can be
either “Freq” for a call made at a regular
frequency throughout the day or “Time” to
specify up to 8 individual times during the day.
Enter either the frequency (e.g. 00:05 minutes) or the time for
the call in the box.
viii. Alarms –The Multilog LX 2 has a comprehensive alarm system
that you can configure to send out Alarm messages when
certain defined conditions are breached.
When an alarm condition is triggered a new call frequency can be specified to
allow the observer to gain more up-to-date data during an event.
Minimum Night Flow is
measured between Midnight
and the time specified here.
Choose your flow units
If you want SMS alarm
messages to be sent, tick this
box and enter a phone number
There are 8 possible different
alarm conditions that can be
configured, select each one
from the tabs.
Choose the main alarm channel
and then the difference channel
if making a comparison.
Set your persistence or trigger
point, e.g. 3 occurrences out of
5 incidents triggers the alarm
Choose your type of alarm from
the list:-
Lower or Upper Limit breach Enter the alarm threshold
Minimum Night Flow (MNF) not met
Rate Of Change (ROC) faster than x per minute
Difference (Dif) between channels greater or less than limit
Either In or Out of Band set by Upper & Lower levels
Note on Hysteresis: When an alarm is triggered, if the value is
set to zero then immediately the threshold is re-crossed then
another clear message will be sent. If there is a period when the
alarm threshold is borderline, this can result in numerous
messages for the same event. By specifying a value in the
Hysteresis box, you can provide a window that allows the
threshold to be repeatedly crossed without sending repeated
messages. e.g with an Upper limit of 5 and a hysteresis of 1, the
alarm will trigger at 5, but the clear message will not be sent
until the value drops to below 4.
Enter the alarm
clear Hysteresis

11
3. Final steps –By default the logger is set to UTC
(Coordinated Universal Time, equivalent to GMT),
however you can choose either an offset from this time,
or for the logger to use your PC time.
When you are happy with all the settings click the
<<Setup Logger>> button to program the logger.

12
Enhanced Recordings
The logger is capable of making additional recordings at higher than
normal sampling rates. It works in two basic modes, Recording at
specific times to allow you to manually set events to be recorded at
higher speed and Recording triggered on alarm event where the logger
monitors a sensor and if the value exceeds that programmed then the
logger makes a recording.
1. Choose your Sampling Frequency.
You can select either the base system
Sample Interval, this is the rate that the
logger normally samples at before
making its average calculation, or you
can choose one of the available Sampling Frequencies (greater
than 1Hz).
2. If available, choose the channel you wish to sample. Note that the
faster sampling rates are fixed to the primary analogue recording
sensor, e.g. Pressure, so you cannot select any other channels.
3. Now choose your operating mode.
Recording at Specific times
1. Choose the duration of the recording or
set the Stop time for a specific time
period.
2. Choose the repetition settings.
3. The logger will make recordings and
send them to the data system at the
pre-determined times.
Recording triggered by an external State Switch
1. Choose which switch state should
trigger the recording.
2. Choose which digital input that the
switch is connected to.
3. Logger will now start the accelerated recording when the switch is
closed. Note that the state switch is sampled once per minute
regardless of the sample rate setting. If faster rates of state
checking are required, the standard alarms should be used.

13
Recording triggered on alarm event
1. Choose the amount of data to be stored
before the alarm is triggered and
duration of the recording.
2. Configure your alarm condition to trigger
the recording. In this example, the logger
will trigger a recording of 16mins
(including 1m from before the trigger)
when the alarm for the primary analogue
channel (e.g. Pressure) passes the upper level of 52.0
Additional notes:
The data will be displayed on HWMOnline as additional traces on the graph
for a Sample Frequency setting of Sample Interval. For higher Sample
Frequency rates the primary trace on HWMOnline will display a diamond
symbol to indicate the point where a transient occurred.
Click the diamond to provide a close up view of the transient

14
Data Communications Confirmation –GPRS Test
It is important to confirm that your logger is communicating with the data
server before you leave site (or to be confident, your office), so you should
undertake a GPRS test before you leave the logger in the field.
1. Connect an appropriate GPRS antenna to the FME socket on the
logger. The location on the logger can vary depending on the
configuration of logger ordered, but the picture below illustrates a
typical connection.
AER6000 antenna
FME Connector
Note: If this is the final Antenna connection, ensure that the connector
is tightened with spanner or pliers to prevent water ingress to the
antenna plug as this will reduce performance. Do not over tighten.
2. Run the IDT and read your logger as in steps 1 to 3 above.
3. Now click the <<GPRS Test>> function button.
4. The GPRS Test program will now automatically execute a
communications check with the data server, DataGate™ and deposit a
test message that can be checked later on.
The test will take a few minutes
and will confirm that the
communication is successful.

15
Troubleshooting a GPRS test failure.
There are a number of reasons why a GPRS test may fail,
the following points should be checked before calling HWM support for
assistance:-
Possible Problem
Solution
Network Busy due to
excessive traffic. Commonly
occurs around schools.
Retry the test after a few
minutes.
GPRS signal not available at
your location. Not all Cell
masts carry GPRS traffic
The logger will call into the data
warehouse once per day using
an SMS message; relocate the
logger if more frequent
communications is required.
Network signal not strong
enough. You need a CSQ
(reported by the GPRS test)
of at least 8 for reliable
communications.
Relocate the antenna if possible
or try alternative antenna
configurations. Ensure antennas
are vertically orientated where
possible. See Antenna
placement notes section.
APN settings incorrect.
The GPRS tester knows about a
large number of cellular networks
and will try as many settings as
possible and correct any error
automatically.
If there is still a failure, then you
need to check with your network
operator that you have the
correct settings for your SIM.
If you continue to experience problems with communication, you may need to
check the network coverage in your location.

16
Antenna installation considerations
The method of installation at site should be carefully selected.
Signal strength within the cellular network can vary dramatically even within
the same cell; proximity to the transceiver, type of antenna, position and
angular orientation of the antenna, all have a significant effect on the ability of
a device to reliably communicate with the cellular network. To ensure reliable
GSM/GPRS data communications it is essential that the most suitable
antenna is selected and it is mounted in the most appropriate location.
Installing a device without considering the type of antenna and its installation
constraints can lead to disrupted and unreliable data communications and
accelerated battery consumption. The following gives practical advice on how
to minimise potential problems.
General Considerations
Always perform multiple signal strength tests moving the antenna to
different positions (please see below for description of signal strength
test results).
When performing Signal Strength Tests ensure that the chamber
lid/cabinet door is in as close to normally closed position as possible to
ensure an accurate result.
Deploy the antenna as close to the surface as practically possible,
especially when installing in a large chamber.
If the device is installed in an underground chamber consider, where
possible, locating the antenna in a secure position outside the
chamber.
Ensure that the antenna connector is in good condition and correctly
tightened (finger-tight is not sufficient for the type of connectors used).
Adequate tightening of the connector reduces the risk of water ingress
and thereby signal attenuation as a result of changes in impedance.
Never attempt to modify the dielectric seal of the antenna connector, it
is designed to keep moisture away from conducting parts which lead to
corrosion and attenuation.
Consider using secondary environmental protection for the antenna
connector such as self-amalgamating tape.
If a logger is installed in a chamber that is likely to flood (e.g. an
Atlantic Plastics chamber), position the logger upside-down in the
chamber to avoid unnecessarily submerging the antenna connector.
Use the shortest possible antenna lead and ensure that there are no
kinks or tight radius bends in the cable. A kinked cable can cause
signal loss.
Where long transmission leads are required, consider using a low-loss
alternative to corrugated copper cables, e.g. Times Microwave white
braided coaxial cable.
The signal emitted from any antenna submerged under water will be
significantly attenuated; place the antenna in a location where it will not
become submerged.
Always ensure that the latest firmware is installed in the device.

Installation Process Decision Tree
Identify Chamber type
Atplas/Small
Chamber
Side/Hydrant
Chamber
Large (Deep)
Chamber
T-Bar
Fix to Logger top or
underside of atplas lid,
ensuring that the antenna is
as high in the chamber as
possible, 3-4 inches can
make a big difference in
signal strength on
underground assets.
T-Bar on logger
I Bar on chamber
wall
Try the T-Bar as per Atplas
instructions and I-Bar on
chamber wall –use the best
performing antenna in the
position that yields highest
signal strength.
Carant on bracket
T-Bar on logger
I Bar on chamber wall
Try the Carant antenna
attached to a bracket facing
down –do not fit this if the
chamber is likely to flood
regularily. Try T/I-Bar as per
Side/Hydrant chamber
Choose the appropriate antenna and position it within the chamber
Ensure antenna terminal is tightened and wrapped in self amalgamating tape to seal
Perform Signal test with chamber lid/door as close to closed as possible
Signal > 14
This is a sufficient signal
strength for good
communications
Signal 7-14
1) Try an alternate network
logger/SIM card
2) Try an alternate antenna
location
3) Try an alternate antenna
Use best antenna/location
combination.
Signal <7
1) Try alternate antennas /
positions as per 7-14
2) Try to locate an I-Bar
externally (above ground)
where considered safe to do
so.
3) Recommend site for
above ground Antenna
installation. Take supporting
photographs.
Complete GPRS test to confirm correct communication
Ensure antenna terminal is tightened to and wrapped in self amalgamating tape to seal
Phone office (if possible) to confirm data is arriving

18
Cellular Network Signal Strength (as measured by CSQ Test)
0-7 Insufficient, the device may be able to register with network but
will not be able to send or receive data reliably.
7-14 Marginal, depending upon the ambient conditions data
transmission may be possible, important to select the correct
antenna and install it in the most suitable location.
14-21 Adequate, Data transmission should be reliable.
21+ Ideal, Strong signal strength data transmission will be reliable.
Antenna Options
Carant Monopole antenna –For most installations the Carant antenna will
give the best performance.
Carant Installations Considerations
For optimum performance the antenna requires a metal grounding plane,
consider installing a metal bracket made of a ferrous material to attach the
magnetic base of the antenna.
Install the antenna near to as close to the surface in large underground
chambers, ensuring that the lid will not interfere with the antenna when
being opened/closed.
This antenna is vertically polarised, it should always be installed in the
vertical orientation.
Never bend the radiating element of the antenna
The Carant can also be attached to an installation bracket mounted to
an existing marker post

19
T-Bar –This antenna is ideal for installing on top of the device especially in
locations with restricted space.
T-Bar Installations Considerations
Adhere the antenna to external structures using marine quality
adhesive (such as the brand ‘Goop’).
Keep the antenna cable as short as possible, 0.5m.
Avoid attaching the T-Bar to a metallic surface as this can adversely
affect signal strength and performance, however it may be better than
underground
