Note(s):
1. Loggers will be set to call in with meter reading data and other messages to a
server. This could be one of the HWM central servers or to your company’s own
server (with HWM logger communication software installed).
2. Your logger may be pre-configured with a security setting requiring the use of
the HWM DataGate or FCS OmniColl central servers; these are referred to as
“secure loggers” and notes 5, 6 and 7 apply (see below).
Without this security setting, the loggers are referred to as “insecure loggers” and
notes 5, 6 and 7 do not apply (insecure loggers can be used without DataGate).
Alternatively, notes 5, 6 and 7 can be optionally applied (insecure loggers can be
optionally used with DataGate).
3. IDT will allow use without the app first logging in to the DataGate server (see link
at the app login page) but will only work with insecure loggers.
4. For additional information, refer to main product manual,
MAN-157-0002 “User Guide: COMLog2-IS / ISLog - Installation and Setup”.
5. Loggers must be pre-registered on DataGate.
6. User must be pre-registered on DataGate.
Contact your System Administrator (or your HWM Sales representative) to obtain
your server URL, username, and password information, etc.
7. Assumes DMAs are pre-registered on DataGate.

3INSTALLATION
1. Un-pack logger
Dispose of packaging
responsibly.
2. Install logger.
This product is only to be installed and connected by a fully ATEX trained installer.
Check on available space in the meter cabinet and decide where to position the
logger, antenna, and cables. Ensure there is access to the magnetic sensor (see 4).
Securely mount the logger with suitable fixings; keyhole mounting holes
are provided.
Note: The logger should be installed upright (pictured) to give best battery life.
If required, add anti-tamper seals between lid and base using holes provided.
3. Connect antenna to logger
Place the antenna in a suitable location.
Connect antenna to the logger.
Ensure antenna cable has no sharp bends.
4. Connect logger to meter output(s).
Connect the logger Flow1 input to the
meter output.
Use a suitable adapter cable if required.
Alternatively, where a volume corrector
is in place, Flow 2 can be used for
corrected meter flow.
Use a suitable adapter cable if required.
If required, activate pulse repeat outputs of the logger, and connect to any downstream
equipment (not shown).
Locate the cables so they cannot be damaged or cause a trip-hazard, and secure in position.

4ACTIVATE LOGGER /WIRELESS COMMUNICATIONS
Logger must be activated during installation.
Hold a strong magnet in the position shown.
Wait 12s, then remove the magnet.
•If logger Bluetooth-compatible communications
is in standby, it becomes active.
•Logger communications stays active for 120s,
waiting for IDT to communicate.
•Communication with phone remains open
for 600s after last use.
5CHECKING AND ADJUSTING LOGGER CONFIGURATION.
1. Read barcode / Bluetooth scan
Tap “Barcode Scan” icon.
Scan barcode of logger.
IDT connects to Logger.
If fail, try (4) again.
Alternative:
Tap “Bluetooth Scan”.
Select logger from list; IDT connects to logger.
Note: When using IDT app with DataGate login, insecure loggers may be hidden from lists.
There is a menu option to view both secure and insecure loggers together.

7
2. Setup Logger ID and time-zone
Tap
“Configure Device”.
Tap
“Device Information”.
Set local time-zone.
3. Display existing Channel settings (summary)
The required logger settings will vary according to the meter and other equipment used at
the site.
Tap the Channels icon.
(A “Combo” is a way of
setting a combination of
conditions that, together, can generate an alarm).
A summary of number of channels and combos
already configured is shown.
(The illustrations opposite show an example of a single
flow channel with Tamper alarm set).
Flow channels appear as Logging channels. A tamper alarm
uses a status input which appear as a Trigger channel.

8
4 Check / Edit logger Flow Channel 1 settings
Tap the Flow channel line to show its details.
This screen is to set the volume measurement
characteristics of the logger to match the meter’s pulse
outputs.
Note: These details can normally found within the
data-sheet for the meter, but typically are found
on the meter or pulse-head, as shown below.
The meter unit above is metric, so the logger
is required to be set up to use metric units (m3).
Check the “BASIC” tab channel settings match the meter, and if not adjust the settings.
e.g. Using the gas meter pulse characteristic shown above…
•The sensor type is set to Gas.
This matches the meter. ✓
•The unit of measurement shown is set to ft3, which is an imperial measurement. 
- The channel requires adjusting to a metric measurement unit.
Tap on “Recording Unit” and set to m3.
•The “Units / Pulse” field now requires editing. The volume represented by the
meter-pulse needs to be scaled to the setting of the Recording Unit field.
“1 PULSE = 100dm3 “ corresponds to 0.1 m3of gas per
pulse.
The channel therefore requires adjustment of the
“Units/Pulse” to be 0.1 to match.
•For a Flow reading, the channel must be set to “Spot”
(the result is the pulse count since last measurement).
The edited screen is shown opposite.
(Settings are correct for this example).
If any settings were changed, tap on the “ACCEPT” button.

9
5 Check / Edit logger Flow Channel 1 Pulse Sample rate and Pulse replication settings
Tap on the “Advanced” tab.
Check the channel settings…
•The “Global pulse sample rate” should be set to
“Low Power” for most meters, for best battery life.
(Pulse width minimum 500ms, 50% duty cycle).
“High Speed” must be set for meters with high pulse
rates. (Pulse width maximum 10ms, 50% duty cycle).
Refer to the datasheet of the meter.
•If required, the “Replicate Channel” control should be active, as pictured.
(This setting ensures pulses from the Flow input are duplicated on the corresponding
output, allowing down-stream equipment to use the meter pulses).
If any settings were changed, tap on the “ACCEPT” button.
6. Check / Edit Flow Channel 2 settings
If the logger is dual channel, repeat the checks
and adjustments (steps 4 and 5)
for the second meter measurement
(e.g. from the volume corrector).
(Only required on dual-channel models.
For single-channel models, the option is
replaced by a Tamper Alarm option; see below).
7. Check / Edit logger Tamper Alarm settings
Some logger models can support a Tamper alarm to detect un-plugging of the logger from
the meter.
If the logger is single channel, and the meter supports a tamper alarm, then confirm this is
set up (see end of description). If not, follow the instructions below:
Tap on Combo:
No combos have been
set up.
Tap on the “ + “ line.
Ch1✓ Ch2 ?

10
Tap on “Tamper Alarm Combo” to set up the tamper alarm.
(This activates IDT to make several changes to logger settings in
order to produce a Tamper Alarm).
The tamper alarm settings are shown below (a) and (b):
(a)
A new channel is
created measuring the
open-circuit time of
input Status2 (/ Flow2).
The channel input is
tested every 2 seconds.
The channel is not
logged.
The tamper input is
not replicated to any
output channel due to
the “Replicate channel”
control being switched off (see diagram).
(With this setting is not available for use by other equipment).
(b)
There is an alarm condition set up
(via a “Combo” condition test).
The test checks the last 20 samples.
The OK condition (non-tamper) is for a closed-circuit to be
present; the time of an open-circuit condition is to be “0”.
The settings opposite create a trigger condition as soon as
a single measurement shows an open-circuit condition
exists.
The Action taken is to immediately report the alarm (to the
server). It is to report it as a tamper condition.
(Functionality and settings in the server determine if the
alarm is just recorded, or if it is actively forwarded to alert a
user).
When the triggering condition no longer exists, the logger will also send an “alarm cleared”
message. However, this will be sent when the unit next calls in to the server, not
immediately.

11
The channels summary shows
the presence of the newly
added channel and a combo
being set to trigger in the new
channel.
A summary of the
tamper alarm combo
is shown opposite
and can be used to
check if the combo
has already been set.
6SET METER READING OF FLOW CHANNEL(S)
1. Set logger with current Meter Reading.
The logger tracks the volume of gas passing through the meter (from the pulses) and sends
a meter reading into DataGate when it calls in with the flow measurements data.
Initially, the logger has not had the meter value set.
Tap on “Metering Settings”.
Find the units the meter is displaying. For the meter in the example we are
using, the dial clearly states “m3“(see diagram opposite).
The “Meter Factor” must next be determined and entered.
Meter factor =
In our example: The flow channel was set up in m3and the meter similarly measures in m3.
The ratio would be 1 m3/ 1 m3;
Set “Meter Factor” equal to “1”.
Example 2: If the flow channel measured in ft3, whilst
the meter measures in 100s of ft3,
the ratio would be 100 ft3/ 1 ft3;
Set “Meter Factor” equal to “100”.
Unit of volume measurement used on the Meter for each digit
Unit of volume measurement used on the Flow channel

12
Read the main meter, noting its format.
Enter the meter reading into the “Initial reading” field.
When entering the meter
reading, include any
leading zeros, the decimal
point and any other
displayed digits.
For the example shown,
enter “020339 . 82”.
Tap the back-arrow and the entered reading for Meter 1
is now shown. (This is not a live value).
You can confirm logger is set up correctly by doing the
following:
After waiting for the meter to change by a few digits,
note the meter reading and tap the “Meter Settings”
control.
Confirm the “Current value” reading matches the meter
reading (noted earlier).
If the reading is not correct, re-check:
The cables go to the correct meter.
The meter factor is correct.
The channel settings (units/pulse and recording unit) are correct.
… and then repeat the test.
Where two flow channels are used, the meter reading entry
page will be as shown opposite.
Make the settings (as above) for each meter.
Add the initial reading and Meter Factor for the second meter.
Then tap the back-arrow.
A meter reading is now
shown for both meters.
Confirm the readings of both “Current value” fields are
operating as expected, using the method described earlier.
