PC Application
Installation
To install the software, please contact our sales team who will arrange for an engineer to install your
software remotely.
Future versions will include an installation programme which will complete the process
automatically.
Starting the Application
To start, first connect your AT-100 to a spare USB port on your computer using the USB cable
provided. Unscrew the battery cap to expose the USB port in the device. Remove the batteries and
connect the USB cable. The front of the device will illuminate in green to indicate USB is connected.
Locate the shortcut to the application and double left click it to start. The application will start in a
new window.
Four tabs are available: Report, Settings, Info and Update… . Also three information boxes are
shown at the bottom of the window, showing USB connection status, system time and date (from
your computer’s clock), and AT-100 device status. The device status box will update with the current
temperature measured by the device every time the USB link is active.

V0.2 Page 6
Report tab
The report tab is used for downloading recorded temperature data from the device, and provides a
graphical display as well as a text summary.
Select the “Download Data”checkbox. “Summary” will appear next to “chart” to indicate the chart
and data type being transferred. The device user name will appear in the User box, the text window
and the chart, and the serial number will appear in the text window. Summary date, time and
temperature data will be transferred from the device, starting with the most recent records and
proceeding to older records so that the latest data are readily accessible. As the transfer progresses,
2-minute blocks of data are summarised by block reference, start date and time, and maximum
temperature in the right-hand (text) window. After a short delay, the maximum temperature,
thresholds and date/time are plotted on the chart.
When the desired date/time range has been displayed in the text window, left click the “Download
data” checkbox again to terminate the transfer. Left click “OK” when a message box appears
showing “Data download complete”.
The AT-100 records data in 2-minute blocks. Please note that in its default configuration, 2-minute
data blocks are only recorded if they contain at least one temperature record exceeding the active
threshold. This causes gaps in the date/time information (when the temperature was too low to
record) but compresses the data for faster and more efficient transfer.

V0.2 Page 7
You can zoom in to select any particular region of interest on the chart. Move the cursor into the
chart area and position it over the start or end of the region you wish to inspect. Click and hold the
left mouse button, drag the cursor to the other end of the region of interest, and release the left
mouse button. The chart will zoom to show this area, and the “Start” and “End” boxes will show the
selected start and end dates/times.
Now select “Download Data” again. The chart and data windows will clear, “Detailed” will appear
next to “chart” to indicate the chart type is now detailed. The complete data record for the selected
period will be transferred from the device, and the text window will show block reference, start date
and time, and both maximum and minimum temperatures for each 2-minute block. The chart will
update to show full temperature details at one point per second. Left click “OK” when the “Data
download complete” message box appears again.

V0.2 Page 8
Again, you can zoom in on the chart to select an area of interest by dragging the cursor as before. A
horizontal scroll bar will appear with a button to the left. You can use the scroll bar to inspect other
areas of the chart. Left clicking the button will zoom out to the previous zoom level.
The chart can be saved, and/or the text data can be saved or printed, using the “Save Chart”, “Save
Data” and Print Data” buttons.
To access temperature data from a different period, select the “Clear Data” button. This will clear
the chart and text windows and reset the transfer settings. Select the “Download Data” checkbox to
transfer the summary data again, allowing you to select a different region for transferring detailed
data as before.

AT-100 device
Installing batteries
To install the batteries, unscrew the rear cap (marked with the battery symbol ). Insert two
good-quality AA alkaline batteries, negative terminal first. Replace the rear cap, tightening until the
yellow LED illuminates and the unit is sealed.
When the batteries are properly connected, the front yellow LED will illuminate briefly, then a self-
test sequence initiates. The front and rear LEDs will illuminate in sequence (red-yellow-green), then
the vibration signal will activate. Following a successful self-test, the unit will reset and commence
normal operation.
If the self-test does not complete successfully, first unscrew the rear cap. Remove the batteries and
check that they are inserted correctly (negative terminal first, positive terminal towards the rear
cap). Re-fit the rear cap and check that it is tightened fully. If the self-test still fails, replace the
batteries with known new, high-quality alkaline cells. If the self-test continues to fail, return the AT-
100 for servicing.
Please note that the AT-100 is not designed for use with rechargeable batteries.
Mounting the AT-100
The AT-100 may be installed in a torch mount with minimum 32mm circular aperture, or in the
universal bracket if supplied. For bracket selection and fitment, please refer to the instructions
accompanying the bracket kit.
Once the bracket is attached to the helmet, insert the AT-100 from the rear. Adjust its position and
orientation so that the front LED is visible in the user’s peripheral vision. Once the positioning is
correct, secure the unit in place by tightening the retaining grubscrew with the Allen key provided.

Alarms and indicators
The AT-100 has a number of operating modes depending on temperature. Additionally, the device
can be configured to record temperature data continuously when on battery power, or (factory
setting) only when the temperature exceeds the active threshold during the current 2-minute
recording block (see “Administrator settings” above).
Ready mode –active when temperature is below the Active Threshold. The front LED flashes
every five seconds. The colour of the front LED indicates battery condition:
oGood battery –indicated by green LED.
oWeak battery –indicated by yellow LED. Be prepared to change the batteries as
soon as the red indicator shows. However, the AT-100 will remain fully operational,
and may be used in high-temperature environments, while the battery status is
yellow.
oLow battery –indicated by red LED. Change the batteries as soon as the red
indicator shows. DO NOT ENTER A HIGH-TEMPERATURE ENVIRONMENT as the
accuracy and efficacy of the temperature alarms could become compromised.
Active mode –active when temperature is above the Active Threshold and below the
Warning Threshold. Indicates that the AT-100 has detected temperatures above the Active
Threshold and is recording data. The front and rear green LEDs flash every three seconds.
Warning mode –active when temperature is above the Warning Threshold and below the
Danger Threshold. Warns the user that temperature exposure is approaching dangerous
levels. The front and rear yellow LEDs flash every three seconds.
Danger mode –active when temperature is above the Danger Threshold and below the
Critical Threshold. Indicates dangerous levels of temperature exposure. The front and rear
red LEDs flash every three seconds.
Critical mode –active when temperature is above the Critical Threshold. Indicates
potentially life-threatening levels of temperature exposure. The front and rear red LEDs and
the vibration signal activate three times, repeating the sequence every three seconds.
Error –indicates possible failure of the temperature sensor. Front and rear LEDs flash in a
green-yellow-red sequence, repeating every ten seconds. DO NOT ENTER A HIGH-
TEMPERATURE ENVIRONMENT as the temperature alarms may not be functional. Return the
AT-100 for servicing.
The factory-set alarm levels are:
Ready –below 40°C
Active –40-50°C
Warning –50-100°C
Danger –100-150°C
Critical –above 150°C
These settings can be changed in the PC application, by an Administrator on the Settings tab.
