Start
Options
Push Button Start – Each LogTag has a Start button. Selecting Push Button
Start means the Logger will not begin logging until that button is pushed. This is
the option to use for vaccine frid
g
es.
Record
Options
Record Readings Continuously – Most often you will want to choose the first
option. This will record until the memory is full and then keep recording new
reading while deleting old readings to fit them in. This way, no matter when you
download the data, you will always record the latest temperatures. You should be
downloading and clearing your data logger weekly though, so it should never get
‘full’. We recommend that you leave the Number of Readings to Record setting
at its maximum.
Sample rate
“Record a reading every” is the sample rate. This is how often the Logtag will
measure and store the temperature. Set this to ‘5 min intervals’ as per the NSW
requirements for monitorin

After
Because the logger might experience a very short fluctuation in air temperature,
e.g. when someone opens a refrigerator door, we recommend using the first After
box to set a delay before the Red LED begins flashing. If you set this to 4
consecutive readings, that means, on a five-minute sample rate, the logger will
have to have been out of range for 20 minutes before the Alert light starts flashing.
This will minimise false alarms. Leave the second ‘After’ box clear.
Clear and
reset
The “clear and reset alert” option allows the user to press the “Clear” button on the
logger to stop it flashing red and start flashing green. Tick this box to allow this. If
a staff member ever notices the alert light flashing – they should immediately
quarantine the fridge until they investigate with a data logger download to the
computer.
Passwords
Do not enter a password in the password fields, unless you specifically require
the security feature. If you lose or forget the password, there is no way for you to
retrieve it without sending the logger back to the supply company.
Push Button Start
If you selected Push Button Start in your LogTag configuration, the logger will now be waiting for you
to start it.
Press and hold the Start (or Start/Mark) button for about a second until both the red and green LEDs
on the front of the logger flash for a few seconds to show that the logger is starting. After that, the
green OK LED will flash briefly about every 8 seconds to show you that the logger is recording.

STEP BY STEP DETAILS
1. Remove the data logger from the fridge
2.
Press the STOP button
This will stop the logger from reading temps
whilst it is out of the fridge)
Press the START/MARK button
Press and hold the Start/Mark button for
about a second. Both lights will flash briefly.
This will put a mark on the results graph that
you can reference.
By default, pressing the Start/Mark button
will not stop the logger, but it will leave a
mark on the graph. This is essentially a way
of marking when the logger was removed
from the fridge, so if the temperature rises,
you can see it was because it was out of the
fridge
3. Connect the data logger to your computer (using the Dock or using the USB depending on
your model type) and Open the LogTag Analyzer software (if it doesn’t automatically launch
for you).
4. Download the data. If it doesn’t do this automatically – select the ‘Download’ option from the
menu
QUICK STEPS FOR DOWNLOADING WEEKLY
1. Take data logger out/off the fridge
2. Press the Start/Mark button (for LogTag models with a desk top dock)
or Press the STOP button for LogTag USB models.
3. Connect data logger to computer
4. Download data (it saves automatically)
5. Clear data (using the ‘Quick Re-configure’ option on the computer)
6. Restart data logger (hold down the START button until both lights
flash)
7. Put back into fridge (don’t leave the data logger on your table for
extended periods of time whilst you analyse the data. Put it back in
the fridge first)
8. Now analyse the data that was just saved onto your computer

5. A box (Figure 1) will briefly appear telling you that the Reader has found your LogTag.

The Reader will read the data from your LogTag and save it to your computer to the default location.
Once the data has been saved, LogTag Analyzer will automatically open your report.

Clearing, Resetting and re-starting the data logger
It is best to clear the data after each download so that each weekly download only includes data from
the previous week’s readings.
Before unplugging the data logger from your computer, click up the top of the software on LogTag -->
Quick Reconfigure. This will re-program the logger with the same settings and clear it ready to start
again.
DON’T FORGET - press and hold the START button again when you are putting it back in
the fridge.
Press and hold the Start button for about a second. Both the red and green LEDs
on the front of the logger will flash for a few seconds to show that the logger is
starting.
After that, the green OK LED will flash briefly about every 8 seconds to show you
that the logger is recording.
The data logger is now ready to place immediately back into the fridge.
Return the data logger to the fridge asap
As soon as the report appears, you know that the data has been saved, so it is OK to
remove the logger from the reader (or the USB port) and return it to the refrigerator.
Follow the steps below to clear the data logger first and make sure you press START to
start it recording again).

Analysing the report
There are four parts to the report:
1. Report
2. Graph
3. Data
4. Summary
By default, the graph will show first. The other sections can be accessed by clicking on the tabs at the
bottom of each page.
What to look for
The easiest way to check if everything is OK is to click on the Report Tab at the bottom of the screen.
At the top left of the Report should be two green ticks showing the Alarm Status for both low and high
temperatures.


If you have a red cross, instead of a tick, you know something is wrong. Look for a section of the
Report labelled Recorded Data.
In the second column of this section it will show you the Temperature Statistics, including the lowest
and highest temperatures experienced by the logger. Below this, you will find details of the alarm.
This will tell you how long the temperatures were out of range.

Trouble shooting
Help! My LogTag says it hit -40°
If you retrieve the temperature data from your LogTag and you see a reading of -40°C, don’t panic.
This is just LogTag’s way of telling you it couldn’t read temperatures. Your refrigerator didn’t really get
that low.
So what happened?
It could be one of two things. Firstly, (for data loggers that use a probe cord attached) check the
actual data readings to ascertain if there was an exact time that the data logger displayed a -40°C
reading. If the -40°C is the last reading then what is happening, is that during the time the logger is
disconnected from the probe to download, when it is being walked over to the computer, it is taking a
reading. As the probe is not connected, it cannot take a reading and shows -40°C to show the probe
was disconnected at that time. It is not a fault at all, most practices get it at some stage or another.
The only way of minimising the chance is to reduce the time the logger is disconnected. No health
department will have any issue with this.
To remove the -40 reading from the minimum on the report, you can click and drag on the graph to
zoom in, and cut off the last reading (-40 reading). This will update all the number.
The second option indicates an issue with the probe connection. If you have a LogTag that takes an
external probe, like the one on the left, and you got -40°C readings, chances are that you did not
attached the probe correctly or forgot to attach it at all. Remove the probe and reattach it. Make sure it
clicks into place properly.
If your LogTag has a blue sensor on the side, like the one on
the right, it has an internal temperature sensor and you cannot
attach an external probe.
Sometimes practices with multiple log tags units (more than
one vaccine fridge) may mix up their LogTags and try and
attach a probe to a LogTag that cannot accept one. Usually,
this will damage the sensor and cause the error readings of -
40°C.
Only attach a probe to a LogTag that has a brass attachment
point, like the Tag on the left.
If none of these is the case in your situation and you are getting error readings, call LogTag on
1300 30 33 34 for assistance.
