4. Using the ReLog
ReLog settings
Charging the ReLog
In the box in which you received the
ReLog, you will also find a USB ca-
ble 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 period of time, make sure
that you give enough time to charge
the ReLog properly.
In order to charge the ReLog as fast
as possible, we recommend having
the ReLog turned off and plugged in
to a computer. When plugged in to a
electrical outlet, the ReLog charges
at a slower rate.
Depending on which version of the
ReLog you have in your hands, the
charge time to fully charge the
battery 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 when plugged into a
computer and being turned off.
There are two ways of setting the
sample rate and choosing acceler-
ometer 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
listed as a USB flash drive. Please
note that the location of the USB/
External drives might vary depend-
ing on the settings of your comput-
er and whether other flash drives
are connected.
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 di-
rectly edit the measurement set-
tings 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
Once completed, a new dialogue
box will appear where you can set
different measurement parame-
ters. First, you can choose to use
either the primary or the second-
ary accelerometer depending on
whether you are doing low-acceler-
ation and low-frequency measure-
ments or high-acceleration and
high-frequency 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
between 4,000, 2,000, 1,000, 500,
250, and 125 Hz. The secondary
accelerometer also has three se-
lectable 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 successfully
saved.
At factory setting, the ReLog uses
the primary accelerometer at 32
kHz and logs both temperature
and battery 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
transfer is not perfect it will mean
that the ReLog cannot fully utilise
its capabilities and measure the vi-
brations accurately.
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 pro-
ceed 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 impact on the results of the
measurements. We would recom-
mend 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
option 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 en-
sure 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 at-
tached to the object.
Mounting methods
Mounting by double-sided tape
This will most likely be the go-to
option for most users of the ReLog
as it is likely that you do not wish
to drill holes into the object you are
measuring on. Each ReLog comes
with several 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
magnets you will limit your ability
to measure higher frequencies as
magnets filter away most vibra-
tions 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
measurement has been completed.
Please also keep in mind that most
wax filters out high-frequency vi-
brations, so the resolution on your
measurements will be worse if you
are looking to analyse high frequen-
cies.
Other mounting methods?
From experience, we know that
each environment is different from
the previous one and that some-
times 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.
