4. Using the ReLog
ReLog settings
Charging the ReLog
In the box in which you received the
ReLog, you will also find a USB cable
that you should use to connect the
ReLog to a PC.
When you receive your ReLog unit,
the charge level of the battery will be
below 30%. As a result, if you plan to
measure vibrations for a longer peri-
od of time, make sure that you give
enough time to charge the ReLog
properly.
Depending on which version of the
ReLog you have in your hands, the
charge time to fully charge the bat-
tery will vary a bit as the different
versions of the ReLog have different
battery sizes. The maximum charging
time should not exceed 9 hours for
the largest battery size.
There are two ways of setting the
sample rate and choosing accelerom-
eter for the ReLog:
Option 1 -
Using VibInspect (recommended)
Having the ReLog plugged in to your
PC, open VibInspect and press the
“ReLog settings” button. Choose the
ReLog root folder, which will be list-
ed as a USB flash drive. Please note
that the location of the USB/Exter-
nal drives might vary depending on
the settings of your computer and
whether other flash drives are con-
nected.

17
Option 2 - use the _settings file
When connecting the ReLog to a PC,
you can find the settings file in the
ReLog root folder (“_settings”). You
can use any text editor to directly
edit the measurement settings in this
file. The structure is that of an .ini file
where key value pairs are separated
with an equals sign. An example of
the settings file is shown below
Once completed, a new dialogue
box will appear where you can set
different measurement parameters.
First, you can choose to use either
the primary or the secondary ac-
celerometer depending on whether
you are doing low-acceleration and
low-frequency measurements or
high-acceleration and high-frequen-
cy measurements.
For the primary accelerometer, you
can choose between the sample
rates 32,000, 16,000, 8,000, and
4,000 Hz, and for the secondary
accelerometer, you can choose be-
tween 4,000, 2,000, 1,000, 500, 250,
and 125 Hz. The secondary accel-
erometer also has three selectable
measurement ranges: 8.192, 4.094,
and 2.048 g. Lastly, you can choose
whether or not to log temperature
and battery voltage by toggling yes/
no in the corresponding box. When
you are pleased with the settings,
press OK and a dialog box will tell
you that the settings were success-
fully saved.
At factory setting, the ReLog uses
the primary accelerometer at 32 kHz
and logs both temperature and bat-
tery voltage.
The available values to each param-
eter is shown in bold in the previous
paragraph “Option 1 -Using VibIn-
spect (recommended)”.

4. Using the ReLog
Mounting
How you mount the ReLog is the
most important aspect for you as a
user when it comes to making sure
that the measurements will be as
good as they possibly can be. Why?
Simply because if the vibration trans-
fer is not perfect it will mean that the
ReLog cannot fully utilise its capabil-
ities and measure the vibrations ac-
curately.
To avoid inaccurate results, the fol-
lowing information should be taken
into account.
Preparations before mounting:
Make sure that the surface on which
the ReLog will be mounted is free
from the following:
• Oil
• Grease
• Dirt
• Excessive amounts of dust
• Water/moist
To ensure this, clean the surface with
an industrial cleaner. Make sure that
you, after having cleaned the surface,
wipe it off properly so that there is
no trace of liquids or moisture on the
surface.
Done? Then you are ready to proceed
to the next step!
There are numerous ways to mount
an accelerometer (we will cover most
of them below) and as stated above,
the choice of method has a big im-
pact on the results of the measure-
ments. We would recommend them
in the order as follows:
• Mounting with screws/studs
• Mounting with adhesive tape
• Mounting with magnets
• Mounting with wax/glue
Mounting with screws/studs
Using screws/studs is the best op-
tion but it does require drilling holes
in the object that you would like to
monitor. If you can do this, great! You
will find that this will ensure most
accurate results when measuring at
higher frequencies. We recommend
using two screws/studs on each side
of the ReLog to ensure that the unit is
firmly attached to the object.
Mounting methods

19
Mounting by double-sided tape
This will most likely be the go-to op-
tion for most users of the ReLog as it
is likely that you do not wish to drill
holes into the object you are measur-
ing on. Each ReLog comes with sev-
eral strips of double-sided tape from
3M that you attach to the bottom of
the ReLog.
Mounting with magnets
Using magnets to mount the ReLog
is a third approach if one of the two
above does not work for you.
There are many upsides to using
magnets, such as them making it
very easy to mount and demount the
ReLog. However, when using mag-
nets you will limit your ability to mea-
sure higher frequencies as magnets
filter away most vibrations found in
frequencies above 1000 Hz. If higher
frequencies are important for your
analysis, please use screws/studs or
double-sided tape.
Mounting with wax/glue
If none of the above fits your pur-
pose you can always use wax/glue to
mount the ReLog. Please do keep in
mind that when you use wax/glue it
can be fairly tricky to remove all re-
mains from the ReLog after the mea-
surement has been completed.
Please also keep in mind that most
wax filters out high-frequency vibra-
tions, so the resolution on your mea-
surements will be worse if you are
looking to analyse high frequencies.
Other mounting methods?
From experience, we know that each
environment is different from the
previous one and that sometimes
you have to be a bit creative when
it comes to mounting the ReLog. We
strongly recommend that you use
the mounting alternatives suggested
above, but if you have any questions
around your specific environment
please do reach out to us and we
will be happy to advise what we feel
would be best.
