TROUBLESHOOTING YOUR PEDOMETER
Many
issues may be resolved by taking time to understand the correct operation, use,
as well as the limitations of what pedometers can and cannot do.
Below
are some tips of what to do If you feel your pedometer is not working
correctly,
1.
The step count does not match the number of steps I take, either fast or slow.
Pedometers
are designed to be worn on the waist and detect HIP MOVEMENT by use of a
PENDULUM inside each pedometer. When the pedometer is used correctly, each time
the pendulum makes contact with a sensor, a step is added to the digital count.
A. IS THE PEDOMETER
PLACED CORRECTLY ON YOUR WAIST?
Pedometers must
remain vertical and parallel to the body while walking. If the top of a
pedometer is tilted outward (more common in heavier people or those wearing a
pedometer low on the waistline) the pendulum may not swing freely, and may not
count the number of steps taken. If the pedometer is tilted instead of horizontal
on the waistline, the pendulum may not count the number of steps taken. It is
easy to accidentally bump a pedometer with the inside of the arm while walking
and not realize it. Walkers should occasionally check their pedometer to make
sure it is in the correct position.
Additionally, moving
a pedometer a few inches to the left or right on the waistline can affect the
number of steps counted. Most people find a pedometer works best placed on the
right side, over the hip bone, straight up from the knee. Others, because of
the way their hips swing, find more accuracy with the pedometer out to the
side, along the line where the arm falls straight down. Everyone has a unique
stride, so each person must find the position that is most accurate for them.
B. ARE YOU WALKING A
STEADY EVEN PACE?
For greater accuracy,
walk at a comfortable, steady pace for a period of time without multiple
starts, stops, abrupt turns, or other changes in stride. This is true with any
pedometer model. (More expensive models may claim to be able to distinguish
actual steps vs unintended movement, but the reliability is questionable.)
The numbers on your
pedometer display may not always match the number of steps you’ve actually
taken if you make these kinds of movements, but your pedometer will still be
very close to the actual number of steps you’ve taken. Just as the clearer you
speak, the easier it is for people to understand you, the clearer your
movements are when walking, the easier it is for your pedometer to correctly
count each step you take.
TIP: Pedometers
studied have been shown to be more accurate walking at about 3.5 mph than a
slower pace of 2.5 mph.
C. ARE YOU WEARING
THE RIGHT KIND OF CLOTHING?
Clothing material
that is too thin may cause a pedometer to tilt or move and count inaccurately,
or fall off the waistband more easily. Do not attach to loose or hanging
clothing, or parts of the clothing that shift or slide when you step. A
pedometer is most accurate when placed at the widest part of the waist, where
it will hang vertically. Low hanging pants may cause the pedometer to tilt,
leading to inaccurate readings.
D. ARE YOU READING
THE CORRECT DISPLAY MODE? (MULTIFUNCTION MODELS)
Depending on the
model, multifunction models have some type of indicator to let the walker know
which MODE the pedometer is displaying (such as STEPS, DISTANCE, CALORIES) Some
models display those names, or an abbreviation. Others will show arrows
pointing to the word. Be sure the pedometer is in STEPS mode.
2.
The distance walked, calories burned, or other measurements are not accurate.
If
your pedometer is a multifunction model, the distance walked, calories burned,
and other measurements are calculated based on the number of steps taken. Some,
but not all multifunction models allow you to program your individual stride
and/or weight for more accurate measurements such as distance walked and calories
burned. All multifunction models have built-in DEFAULT measurements if custom
measurements are not programmed into the pedometer, giving the user a general
estimate of those measurements.
3.
The digital display does not show. The screen is blank.
A. DOES YOUR
PEDOMETER HAVE A SLEEP FUNCTION?
Some pedometer models
have a sleep function to save battery power. The sleep function also acts as a way
to keep the pedometer from counting while the user is sitting or standing
still. When no movement is detected, usually about a minute, the display shuts
off. When movement is detected, the pedometer display will come back on and
continue to count steps. The display may not wake up instantly depending on
model.
DO NOT PRESS THE
RESET BUTTON TO WAKE THE PEDOMETER UNLESS YOU ALSO WANT TO SET DISPLAY TO 0. If
the pedometer does not wake up, tap the side of the side of the case with your finger,
and the display will show.
B. DOES THE PEDOMETER
HAVE A BATTERY TAB?
If your pedometer
model came with a tab under the battery, it may not have been removed. Check
for a small piece of plastic sticking out of the side of the case. If the tab
was removed and the display does not show, a piece of the tab may still be
under the battery. Depending on your model, you may be able to remove a panel
or battery door and remove the battery. Some models require a small phillips
screwdriver to access the battery.
C. DID THE PEDOMETER
GET COLD OR HOT?
Exposing
the display to extreme heat and direct sunlight, such as on the dashboard of a
car, may cause the display to go out. The display will return to normal once cooled.
In extremely cold weather, the pedometer display may also go out. Allow the pedometer
to warm up to room temperature before using again.
If your pedometer display
doesn’t show numbers or is frozen, remove the battery from the pedometer and
re-insert. Make sure the plus side (+) of the battery is facing upward.
Depending on the model and features, you may have to re-program your custom
measurements into the memory. See the instruction manual for your pedometer.
IF NOTHING ELSE
WORKS, THE BATTERY IS PROBABLY DEPLETED.
Pedometer batteries
typically last 1 year or longer. In rare instances a new battery may become
discharged. Replace with the same battery and recycle the old one.
4.
My pedometers keep resetting to 0 OR 00000.
A. ARE YOU
INADVERTENTLY PRESSING THE RESET BUTTON WHILE WALKING?
Depending on the
position of the pedometer on your waist, the location of the buttons on the
pedometer, and how you swing your arms when you walk, it's possible to
inadvertently bump the RESET or other button on some pedometer models. This is
less likely to happen with clamshell style pedometers, as the buttons are
covered while walking.
B. IS ANY CLOTHING
RUBBING OR PRESSING AGAINST THE PEDOMETER?
Coats, jackets, heavy
clothing pressed against a pedometer's buttons may cause it to reset.
C. COULD YOU BE
PRESSING BUTTONS WHILE YOU ARE NOT WALKING?
Buttons may also be
accidentally pressed in certain situations while not walking. Here are several
examples: Leaning over while taking a seat, or bending over to tie a shoelace
can press the pedometer against the thigh, accidentally pressing the button. A person
who wears their pedometer closer to the front of their body than the side may
be more likely to press a button this way. The pedometer may also be pressed
against a steering wheel or seat belt if worn in a vehicle. The more overweight
a person is, the more likely this could also happen. Children tend to lean
against table edges, counters, etc, and are more likely to lay on their stomach
or side. This may cause the pedometer to reset.
5.
When I walk with someone, the step counts are different on each of our
pedometers.
Two
different people, walking an identical distance, typically will have two
different step counts on the pedometer
display. There are several reasons for this:
A. DIFFERENT PEOPLE
HAVE DIFFERENT STRIDE LENGTHS.
The shorter your
stride length, the more steps it will take to cover the same distance as
someone with a longer stride length. It is unlikely two people walking the same
distance will have the same number of steps.
B. DIFFERENT PEOPLE
HAVE DIFFERENT WALKING STYLES.
Some people start out
more slowly or quickly than others. First and last step(s) may or may not be
counted depending on how quickly they start or stop. Some people, especially
children, tend to move more while standing in place, which could add to the
step count.
C. DIFFERENT PEOPLE
SIT DIFFERENTLY, AND THE PEDOMETER MAY OR MAY NOT COUNT.
Two different
pedometers may not count the same while sitting or engaging in other
non-walking activities. Some models may interpret certain movements as a step,
others may not. The comparative body shapes of the two people has a factor in
this also, as well as each person's posture. A pedometer may not be accurate if
it is tilted at an angle, or if the case leans forward. If you are comparing
two different kinds of pedometers, each model may have slightly different
sensitivity tolerances, causing one model to count when sitting compared to
another model.
D. PEDOMETERS HAVE A
RANGE OF ACCURACY.
Most pedometers have
a range of accuracy, typically + or - 5%. That is, in taking 100 steps, the
display should read from between 95 to 105 steps. Most pedometers fit this
tolerance range. If you want to compare two different pedometers for accuracy,
the most accurate way is for one person to test both of them. See below on HOW
TO TEST YOUR PEDOMETER FOR ACCURACY.
6.
When I walk on a treadmill or eliptical, the step counts don’t match those on
the pedometer.
Comparing
counts on a treadmill or eliptical is not a reliable way to check for pedometer
accuracy. Pedometers use a pendulum to detect hip movement caused by foot
contact with the ground. Treadmills measure steps by one of several methods. A
programmable treadmill lets you enter stride length. When you walk, the treadmill
counts wheel rotations and calculates the total based on stride length
programmed in. While this is fairly accurate, a walker's steps vary with each
step and may not all be the same length over time. Also, as an example, say the
walker programs in a stride of 25" but their typical stride length is
actually 30" on a treadmill, for every six steps, the counter will
estimate only 5 steps were taken.
A
treadmill is also a moving surface. A pedometer may or may not detect hip
movement compared to walking on a non-moving surface. Some treadmills are
cushioned to reduce impact on the feet, which may also affect step counts on a
pedometer.
Elipticals
may not read the correct step counts either. Pedometers are calibrated to
measure the specific motion of walking. Movement in an eliptical manner is a
different type of movement than walking, and may or may not count on a
pedometer. This is also why pedometers are generally not accurate while riding
a bicycle.
Treadmills,
elipticals and other devices also need to be recalibrated occasionally for
accuracy. Home equipment
is not likely to be maintained in this way. Commercial fitness equipment may be
more likely to be checked for accuracy.
7.
My pedometer counts movement other than steps.
A
pedometer is designed to detect hip movement while walking. However, it may
also count other types of movement.
A. IT COUNTS WHILE I
STAND IN PLACE.
Depending on how a
person stands, their movements may be interpreted as a step, such as bouncing
up and down, twisting or turning, rocking back and forth. This is more likely
in school age children. This type of movement burns a similar amount of
calories that each step will, so if someone is making enough of a movement
while standing in place to get the pedometer to count the movement, it is equal
to taking the same number of steps.
B. SHAKING A
PEDOMETER
If you shake a
pedometer in your hand, it will count. Some models claim to only count steps,
but all models, from the least to most expensive, will add to the step count if
shaken in a way that imitates hip movement. Pedometers have computer chips in
them, but they aren't smart enough to tell if someone is trying to cheat
8.
How to test your pedometer for accuracy.
The
proper way to check on the step count accuracy of any model pedometer: 1) Put
the pedometer on and make sure it is adjusted properly according to
instructions. 2) Press the reset button to set the display to 0 (or 00000).3)
Take 25 evenly paced, steady steps. If the display reads more than 26 or below
24 steps, move the pedometer to the left or right on the waist a few inches.
This changes the sensitivity of the pendulum slightly. Make certain your
pedometer is also level horizontally. Then take 25 steps again to re-test.
Note
that depending on your individual gait, the pedometer may or may not read your
first or last step when starting up or stopping. Your pedometer may not record
sharp turns or abrupt movements. It may record exaggerated movements as more
than one step. Pedometers always work best while walking at a steady, even
pace. It is a good idea to recheck the postion of your pedometer regularly to
ensure it is level horizontally.
COMPARING
TWO OR MORE PEDOMETERS.
Comparing
two different models on two different people is not an accurate way of
comparing pedometer accuracy. To compare one model to another model, the same
person should repeat the same steps with both models, walking at the same pace,
and adjusting each until most accurate. Because the stride, weight, gait and
body shape of each person is unique, each pedometer has to be adjusted to fit
the individual, and continually checked to make sure it is always level.
All
other pedometer measurements on multifunction pedometers are based on step
counts. If other measurements,
such as distance walked and / or calories burned are different on two different
multifunction pedometers, the custom measurements which have been programmed
into each model which may be different. This will give different results, even
if worn by the same person.
