LC6 / LC7 5
Thank you for choosing a test cycle from Monark!
Ideal position is important for performance to reach its maximum. LC6/LC7 has a brand new frame
that is adjustable in all directions. The frame also allows the Q-factor to be reduced, which further
increases the possibilities for a perfect performance. The new setting options, along with an upgraded
braking system, make Monark's renowned bike even better.
LC6/LC7 gives the conditions; the rest is up to the rider.
In today's society we are used to customizing our machines and tools for our own needs. The
same applies to LC6/LC7. Through intelligent solutions parts can be customized according to user
requirements. LC6/LC7 is also prepared for additional equipment, channels behind the covers make it
easy to install different equipment for different needs. LC6/LC7 is a great bike as it is, with additional
equipment, it can be even better.
Force is a strong word which brings many associations. For us, force is interesting when it can be
measured and calibrated. For a brake-force to be correct, regardless of the system, it must be calibrated
and controlled. On LC6/LC7 the brake system and calibration have been updated so that it is safer
and more accurate. It is also quicker to adjust and has more options in that it is speed-independent,
but can be switched into constant braking force as an alternative.
Monark has always been known for the bikes measurement accuracy, now it's even better.

Cycle adjustments
Seat height should be adjusted to a comfortable
position. The appropriate height is to have the knee
slightly bent when the sole of the foot is centred over
the pedal axle with the pedal in the bottom position.
When adjusting the saddle height and vertical
position, loosen the respective locking handles. See
Fig: Overview at page 7.
The handlebar setting should be in a comfortable
position when cycling. During longer exercise sessions
it is recommended to occasionally change handlebar
position. The handlebar can be adjusted both
horizontally and vertically. This is done by loosening
the respective locking handles. See Fig: Overview at
page 7.
NOTE! Be sure that the stem and seat post are inserted
to at least 100 mm in the frame. This is marked with
“MAX” on the stem.
Initial operation
LC6 / LC7 is mechanically calibrated in the factory.
The user may wish to verify this by performing the
mechanical calibration of the pendulum weight. See
”Electronic calibration”.
Apply power to the test bike by first connecting the
cable from the power adaptor to the test bike at the
power connector (3) at the right side of the bike, see
Fig: Front cover right. Then plug the power adaptor
into the wall outlet. Turn on the power switch (2) and
a green LED (1) lights up.
The cable from the power adaptor can be locked
with the clamp (4) which is placed below the power
connection.
Perform the electrical calibration as specified in section
"Calibration Electronics”. Test by pedalling the bike.
If the bike is working properly, it is ready for use.

Power on crank or ywheel
Monark bikes measure the effect of the flywheel, so it
will be a friction of 6-8% if you measure the impact
of the pedals (measure the effect of the crankshaft,
the difference is 4-5 %). These percentages will be
primarily due to friction in the chain, pedals and
bearings.
LC6 / LC7 is designed for fitness tests and is set for
power measurements on the flywheel. The bike can be
set to work with effect in the pedals / crankshaft (the
cycle constant).

Measured quantities
The following units are normally used. Where multiple
units are specified, the user can select, see the software
documentation.
Control of the bike
LC6 / LC7 is built on a solid framework, a large
well-balanced flywheel, a brake belt and a pendulum
that measures the braking force. The pedals operate
around the brake wheel via a chain, while a stretch
mechanism tightens the brake belt to regulate the
braking force to affect the flywheel. This brake force
is given directly by the pendulum against the scale on
the right side of the bike.
The computer system consists of a main unit (built in
the bike) and a control unit (integrated computer on
the bike, PC, terminal or other external equipment).
The main unit reads pedal speed and braking force
and to determine the test subject's heart rate by a
chest belt, where applicable. In addition, the main
unit activates an actuator, which adjusts the brake belt
tension that regulates the braking force. This brake
force is varied automatically in relation to changes in
pedal speed, so that a constant power is maintained
The bike is as default rpm-independent.
For information about how respective control units
works, see respective sections.
The bike can be controlled externally by PC, terminal
or other external equipment.
Here are instructions for connection and options for
connection to external devices. If advanced technical
documentation / data protocol for system builders or
similar are required, contact Monark Exercise AB.
The control is performed over a serial line using ANSI/
ISO/ASCII format commands. Connector, a 9-pin
D-Sub (male) located below the RPM meter, see Fig:
Connector, is compatible with the RS232 standard.
The bike need not be switched off when connecting
external components, but it is recommended to pre-
vent transmission of incorrect data between devices
over the connection.
Be careful when connecting different types of external
equipment to prevent flash-over and subsequent
injury. The user must ensure that the correct cables are
used, otherwise you risk serious injury or equipment
damage.

Checking the pulse function
This bike does not have a meter that shows the heart
rate. However, the heart rate is displayed in the
computer software or other external equipment.
While the patient rests, with the chest belt on, compare
heart rate in the software with the manually taken
pulse. If it does not correspond, check the chest belt
contact area and moisten if necessary the electrode
surfaces with water. Electrodes on the back of the
chest belt. If this fails, call customer service.
The following procedure ensures that the bike works
for daily use.
Check the pulse function, see section.•
Check the brake force, see section.•
Test by pedalling and check that a reasonable•
rpm is obtained - verify by a clock. Feel if the
pedals move smoothly. Listen for unusual sounds.
Remedy if necessary.
Adjust the handlebar and saddle and make sure•
they are securely attached and that the adjustment
is working properly.
Make sure the support legs are in position by•
rocking the bike. Tighten if necessary.
If something unusual is found during the daily
inspection that you cannot resolve, please call
customer service.

Validation Validation of force
Start the PC software (it is available for free download
from our web site: www.monarkexercise.se) and
select a test programme from the menu "Test". In the
dialogue box that opens is a box showing the braking
force in Newton, see Fig: Force and HR display. You
do not have to press "Start" (1) to get the heart rate
showed (2), but you must press "Start" to show the
force (3).
With the pendulum pointer at 0, the display should1.
read "00N".
Move the pendulum pointer to 4 kp and the display2.
should now show "39N".
If the braking force is not displayed correctly, an
electronic calibration must be done. See section
"Calibration electronics".
NOTE!
After this verification, the brake belt will be loose,
which means that it takes about 15 seconds before the
regulating device has tense the brake belt to normal
again (5 N).

Zero adjustment of scale
Check that 0-index (3) on the scale (2) is in line with
the pendulum pointer when the bike is at a stand
still and the brake belt is loose. If not, an adjustment
must be done. Loosen the screw and adjust the scale.
Tighten the screw (1) after adjustment. See Fig:
Adjustment scale.
Calibration
All LC6 / LC7 are calibrated in the factory, but a
calibration of the pendulum can still be done to verify
this. If so, please do the following.
Open the front cover. Check that the brake belt (3) is
loose. If not, move the pendulum to 4 kp and hold it
there a while to loosen it. Unhook the brake belt from
the spring. Check that scale 0-index is in line with
the pointer. Adjust if necessary, see section "Zero
adjustment of scale".
Calibration weight 4 kg (Art. No: 9000-211) is
hooked on the spring.
NOTE!
The flywheel must be completely stopped before the
weight is hung on!
This weight (4 kg) can, when properly adjusted, be
read at the corresponding point on the scale. If there is
a deviation, adjust the pointer to the correct position
by adjusting the weight (2) inside the pendulum. To
change the adjustment weight loosen the adjustment
screw (1). If the pointer shows too low, the internal
weight must be moved upwards. If the pointer shows
too high, the adjustment weight is moved down.
This process is repeated until pointer is in the correct
position. Hook the brake belt in the spring and close
the front cover.
Check the calibration of the pendulum weight once a
year or when needed.

Electronic calibration - with the pendulum
Calibration electronics
Usually it is not necessary to recalibrate the cycle
electronically, but it should be done after each service,
change of electronic part, movement, if you adjusted
the 0-index, or after you have programmed the
"Reset" by default settings.
The calibration coefficient calculated by the computer
is stored in main memory. No matter when the power
is turned on, the last stored calibration will be placed
in main memory. New calibration automatically
replaces the old.
A check of the electronic calibration can be done in
the computer programme, see section "Validation of
force". NOTE!
The pendulum must be kept still at the different
positions. This is done by pressing down the pointer
into the groove on the scale at each kp value.
Calibration
LC6 / LC7 has a mechanical brake and pendulum
weight, making performance validation a simple
procedure. Calibration is necessary so that the
electronic and the mechanical parts of the cycle
conform. The work carried out on the bike is a
result of the braking force (pendulum mode) and the
number of pedal revolutions (= distance). The effect
is then counted out by dividing the work done by the
time it took to accomplish it. Validation includes both
mechanical and electronic procedures. For detailed
information, see the computer programme's user
manual. If the bike fails to pass any section of the
validation, proceed to the calibration and/or service
menu.
After any repair or service, a "Daily Check" should
be done.
It is also possible to calibrate from the software. See
the menu "Monark Ergomedic" - Check calibra-
tion..." in the computer software.

Testing with LC6 / LC7
The versatility of the LC6 / LC7 enables it to be utilized
in a variety of testing environments. The precision
and reproducibility of the test values obtained with
the bike, along with the uncomplicated way to set up
the tests, means the bike can be used in clinical work
tests, in occupational health services for the fitness
tests as well as fitness centers, schools, sports clubs
and the like.
In general, one should note that stresses on the tested
person can become quite severe, whether in a clinical
work test or a simple fitness test in physical activity
contexts. As a precaution, it may be advisable, prior
to beginning an exercise protocol, that each subject
consults with a physician.
Before testing, the operator should review the entire
protocol operation with the test person, explaining
the work which will be required and the duration of
the procedure. One should also agree on how the test
person shall give signs of any fatigue, chest pain or
other abnormal physical reactions.
The test person should not engage in heavy physical
activity for several hours prior to testing to establish
maximum oxygen consumption. In addition, all
testing and exercise protocols should be performed
a reasonable time after meals. The test person should
also refrain from smoking within an hour of the
testing period.
The tested person shall also have the appropriate
clothing for a work test. Training suit or loose-
fitting clothing is best. More detailed instructions
are rarely needed, regarding the ride, but it may
still be appropriate for the test leader to give some
advice on pedalling, saddle height and position of
the handlebars. It should be comfortable to ride. The
appropriate height of the saddle is when the knee is
slightly bent when the sole of the foot is centred over
the pedal axle with the pedal in the bottom position.
Let the test subject try to ride with low workload and
see how it feels to hold a steady rpm.
Finally, the chest belt shall be put on, see Fig: Placement
heart rate belt in section "Heart Rate (telemetry)" for
correct placement. Check for a minute that a proper
heart rate is displayed. The baseline heart rate may
also be of assistance in determining the nervousness
of the test subject. It may be appropriate to let the test
person rest long enough before the test so a more or
less stable resting heart rate can be read.
Power calculation
1 rpm = that a point on the flywheel moves 6 meters
per minute.
50 rpm = 300 m
2 kp force makes 2 x 300 = 600 kpm/min
100 rpm= 600 m
1 kp force makes 1 x 600 = 600 kpm/min
Exact calculation:
Watts = rpm x kp x 0.98065
"Rule of thumb" calculation:
Watts = rpm x kp
(2% error, but may be good enough in many cases)

Test person enforcement
The bike performs automated tests virtually by itself,
requiring minimal intervention by the test operator.
This allows the operator to pay careful attention to
the test person without distraction. The response to
the exercise protocol can be accurately estimated and
appropriate action taken to assist the test person, if
necessary. Some programmes have sections where
the test person may develop significant physical
activity. The effect on the test person should not be
underestimated.
During the test it is important to observe the test
person's appearance and heart rate. The testing should
be stopped immediately if the test person reports chest
pain, difficulty in breathing, etc. A system of prompt
medical attention should be set up prior to testing, in
case of emergency.
The test person may also have difficulty in keeping a
steady pedalling speed. This is of minor importance
(except in cases where the program assumes a constant
braking force, since the effect is automatically adjusted
to the correct value as long as the pedal speed is at least
35 revolutions / min (rpm)). However, it is important
to consider what each test documentation says about
the pedal speed.
Heart Rate (telemetry)
A person's heart rate can be measured with a chest
belt that senses the electronic output of the heart. The
chest belt is standard equipment.
The bike does not have a meter that shows the heart
rate, however, the HR is displayed in the computer
programme or in other externally connected devices.
Fuss-free HR measurement requires that the belt is
correctly placed. When it is correctly fitted the logo
on the belt will be central and readable, outward
and upright, by another person. Before putting on
the belt, clean the skin where the belt is to be placed.
The chest belt should be secured at a comfortable
tension around the mid section, just below the breast
muscle, see Fig: Placement of the chest belt. Moisten
the electrodes before use, see Fig: Electrodes on the
back of the chest belt. To make contact with the HR
receiver on the bike, the distance should not be more
than 100 cm / 39 1/3". It is especially important when
first used to identify the chest belt with the sensor, by
standing close to get the HR (maximum 60 cm). This
relates especially to the Polar heart rate belt.
NOTE! Electromagnetic waves can interfere with the
telemetry system. Cellular phones are not allowed to
be used near the bike during test.
In case of problems, turn off WiFi, Bluetooth and
similar on computers nearby (including the display
with integrated computer on LC7).

Reviewing results
The maximum oxygen uptake is a
standard measure of the condition of the heart- and
lung-functions. Dependent on the linear relationship
between work and oxygen uptake and between work
and heart rate, the heart rate response to work may
be used to estimate the oxygen consumption. If the
maximum heart rate is considered, the maximum
oxygen consumption may be determined.
The YMCA and Åstrand protocols estimate
the maximum oxygen consumption, based on a
submaximal workload while all others report the
oxygen consumption required by the final workload.
The Bruce and Naughton protocols require that the
test subject exercise at a workload level for a minimum
of one minute to establish the oxygen consumption.
If less than one minute is observed, the previous
workload value is used.
The estimated maximum oxygen consumption
derived from some of the ergometer tests is subject
to the error of the “age related predicted maximum
heart rate“. Although there is a definite and linear
relationship between work and oxygen uptake, there
are some differences in actual oxygen uptake based
on individual work efficiency. Test persons who are
less familiar with bike exercise and those individuals
who are less fit, are more likely be less efficient than
those who ride bikes frequently.
It should be noted that these results are estimates or
predictions of maximal response and have a greater
chance of being in error than if the individual were
tested to their actual maximum value. Interpretation
should therefore be made more carefully with an
understanding of the possibility of errors in the
methodology.
