The ambitious runner can increase the
accuracy further by performing a run-
ning style analysis. The best results
are achieved when you start with the
running style analysis, followed by the
calculation of the personal multiplier.
Now the different calibration routines for
the occasional (personal multiplier) and
ambitious runner (running style analysis
and personal multiplier) are described in
detail. Normally the error can be re-
duced to 4% by the calculation of the
personal multiplier alone. While the
calibration with running style analysis
and personal multiplier reduces the error
to
±
2%.
Calibration for the occasional runner
For a better understanding of the
calibration for an occasional runner
please imagine a numerical axis. If you
run the same distance at different
speeds the results might be like this:
The mark below the axis represents the
true distance of your run. Above you see
examples of displayed distances for
various running speeds.
By calculating the correct personal
multiplier the balance point of the error
is optimised. This will reduce the error
for the slow running speed in the exam-
ple above. On the numerical axis you get
the following picture:
The calculation of the personal multiplier
reduces the average difference from the
true distance.
Calibration for the ambitious runner
Before the calibration starts the following
randomly chosen initial state should be
valid.
The running style analysis allows the
Jogging Speedometer to adapt to your
personal technique. To stay in the pic-
ture of the numerical axis the results
after the running style analysis might be
like this:
The displayed distances are now inde-
pendently from your speed and in a
close range. Normally already close to
the real distance also. But there is still a
possibility to get a systematic error dur-
ing the running style analysis. I.e. mis-
takes in measuring the 50m distance or
stopping to late/early after the finish line
of the calibration run. This systematic
error can be compensated by the run-
ning coefficient which is also called
personal multiplier. When you set the
personal multiplier to the correct value
you will finally get the following result:
No matter at which speed you are run-
ning the displayed distance is always
close to the real distance. The average
error is usually below 2%. If you dis-
cover a lower accuracy there might have
been something wrong in the calibration
process. Please reset the speedometer
and redo the complete calibration. This
procedure can be done as often as you
like and will not damage your Jogging
Speedometer.
The following chapters explain the dif-
ferent calibration routines in detail. The

plier PM.
9a. Running style analysis CALIB
During the running style analysis the
Jogging Speedometer calculates indi-
vidual parameters which describe the
change in your running style when you
change your jogging speed. The closer
you follow the instructions for the run-
ning style analysis the more accurate
the results will be.
Before you actually perform the run-
ning style analysis please read the
following pages carefully. This helps
you to understand the underlying
concept of the routine an well as to
avoid errors during the process.
Put on your running shoes and take this
Speedometer together with all compo-
nents in your speedometer set to the
outside.
Search for a plain running track and
mark a 50m long track. This is easy with
the 10m measuring tape and the white
chalk included in your Jogging Speed-
ometer original packaging.
Put on the display and the chest belt and
activate the transmission between dis-
play and belt by pressing the START
button of your display.
a. Press MODE until you reach the
Speed S or the Distance D Main
mode.
b. Press SET to enter Setup.
c. Press START/STOP until you reach
CALIB off .
d. Turn the Calibration to ON by press-
ing SET/+ or OPTION/-.
e. Confirm Calibration ON by pressing
START.
f. The receiver watch automatically
establishes a communication with
the accelerometer module.
During Calibration, the following will
display:
Upper line: 50:50- indicates the re-
ceiver/watch is using the factory pre-set
values for all variables.
Center Line: i.e. 1:23:08
• 1 - indicates the number of the cali-
bration run (you need to make 3
runs).
• 23 - the approximate number of
steps in that particular 50 meter cali-
bration run.
• 08 - the approximate time in seconds
of the calibration run so far.
g. After the accelerometer and receiver
watch are linked together, a 15 sec-
ond Countdown will start. Display
reads 1:00:15, 1:00:14…
h. After the countdown reaches 0 start
your first 50m run in a slow jogging
speed – this jog should take ap-
proximately 20 seconds.
i. After the finish line STOP! The
Speedometer automatically recog-
