regulating the applied braking force. The force may
be automatically varied in response to changes in
pedal speed to maintain a constant power workload.
For information about how respective control unit
works, see ”Connection to controller”.
Power on crank or flywheel
The Ergomedic 839 Medical is adapted to ECG-work
tests, it is set to measure the power on the crank.
The Ergomedic 839 E is adapted to fitness tests, it is
set to measure the power on the flywheel.
A sticker, placed on the head tube, see fig: ECGsticker, informs that the ergometer is set to measure
the power on the crank.
The Monark Ergometer 839 E/839 Medical can be
controlled externally from a terminal, a computer or
an ECG device. A printer can also be connected to the
ergometer.
The control is performed over a serial line using ANSI/
ISO/ASCII format commands. The interface is a 9-pin
male D-sub connector, compatible with the RS232
standard, located on the front of the electronic box.
To connect to a PC use a 0-modem serial cable with
9-pin female connectors in both ends.
It is also possible to use an analogue control from an
external source to set the workload. This is done by
the contacts b32 and z32 on the main connector on
the bike.
The ergometer need not be turned off prior to
connection of the external components, although
removing the power from all devices may prevent
erroneous data transfer between equipment during
interconnection. Caution must be exercised in the
connection of various types of equipment from
different manufactures to avoid electrical hazards and
physical damage. The user must be certain that the
instrument connector and the cable are designed for
the intended purpose. Serious injury to the user and/
or equipment may result if inappropriate connections
are attempted.
Fig: ECG-sticker
Operation of the ergometer
The Ergomedic 839 E is built on a stabile frame, a large
well balanced flywheel, a break belt and a pendulum
weight which measures the force. Pedals and a chain
drive are provided to spin the flywheel as a tension
device tightens the belt to regulate the braking force
applied to the wheel. The pendulum indicates the
applied force directly on the scale located on the right
side of the flywheel.
The computer system consists of one main unit and
one control unit (terminal, PC or ECG). The main
unit reads in the pedal speed, the applied force
and determines the subjects heart rate by a chest
transmitter. Additionally, the base control activates

The workload of the Ergometer can be controlled
by external devices such as an analog ECG device
(must be between 2 and 4 volts to operate properly).
For settings, see the manual for the terminal and the
manual for the software.
The Ergometer 839 E interfaces to several optional
devices. A parallel interfaced printer may be attached
to provide written reports.
The terminal or the computer attaches both via a serial
cable to the 9-pin interface connector located on the
front of the ergometer. Attach a printer if available to
the parallel port on the front.
If the instrument is a terminal or printer, the system
may need to be set-up. Verify that the System set-up
have been set to enable automatic printout. If it has
been disabled, no output will reach the device until
it has been enabled. Also, the baud rate selected by
the interface cable must match that of the device. If
the device is a printer, proper paper loading and unit
selection must be completed prior to operation (refer
to printer instruction manual).
The automatic printout length is a preset to eleven
inch pages for standard fanfold or zee-fold paper. At
the top of the each page, a header designating the
columns is printed.
The time period between the printing of each line
may be set as desired, from 0 (continuous output) to
255 seconds in one second increments. The standard
setting is 15 seconds between printouts. This provides
reasonable documentation while not wasting large
quantities of paper.

Calibration
Validation
The 839 E is a mechanically weighted and braked
ergometer, making performance validation a simple
procedure. The work performed on the ergometer is
the product of the weight lifted times the numbers
of revolutions (factored). Validation includes both
mechanical and electronic procedures. If the ergometer
fails to pass any section of the validation, proceed to
the calibration and/or service menu (99 in the main
menu).
The following procedure will assure the user that the
ergometer is performing properly on a daily basis.
The test exercises the mechanical braking, pedalling
and speed detecting systems as well as the computer
regulation and sensing capability of the mechanical
system.
Inspection of all mechanical components is suggested
after any repair, or component service. The following
validation should be performed annually:
1. Remove the cover from the flywheel.
2. Loosen the brake belt at the balancing spring.
3. Wait until the flywheel is nolonger moving.
4. The pendulum weight index should be aligned
with “0“ on the scale.
Additionally, if a calibrated ECG simulator is
available, it may be used to verify the heart rate
measuring system. Whether the simulator is used or
not, the heart rate system may be validated by simply
taking a pulse point rate measurement at the neck
for example. While a patient is at rest and has been
prepared for chest belt electrodes or an ear sensor,
the pulse indicator flashes once per pulse beat. The
displayed rate, should agree with the manually
detected pulse rate. If not, check the patient electrode
connection and skin preparation prior to requesting
service.
5. Attach the calibration weight to the point at which
the spring was attached.
Validation of force
6. The known weight should match the value on the
scale. If not see section “Calibration of Pendulum
Weight “.
From main menu go to any start display with Newtons (N).
7. Reattach the tension belt.
8. Reassemble the cover.
1. With the pendulum at zero, the display should
read “ 0“.
Proceed to the validation to complete.
2. Move the pendulum weight to the 4 kp position
and the display should read “39“ Newtons.
3. Decrease the position of the weight by steps of 1
kp. The display should read correctly at all positions.
NOTE!
The brake belt will become loose and because of this
it will take a few seconds before normal workload is
obtained the first time the ergometer is used.
12
Monark 839 E
Electronic calibration
Calibration is necessary to match the mechanics of
the ergometer to the electronics of the computer.
The following steps are required to recalibrate the
electronics to the pendulum scale.
1. Check at the bottom of the flywheel that the brake
belt is loose. If not move the pendulum up to 3 kp
and hold it for a few seconds. Move the pendulum
to the zero position again. Check that the brake
belt is loose.
2. Align the force scale with zero marker
on
the
pendulum.
Refer
to
section
”Zero adjustment of meter panel” for details.
A check of the electronic calibration can be done
as follows: From main menu go to any of the test
windows showing Newtons (N). Move the pendulum
to 4 kp (39 N). This position shall now be read in the
display. If not perform a new calibration.
NOTE!
After this, the brake belt will be loose which means that
the first time the ergometer is used after calibration it
will take a few seconds before normal workload (5
N) is obtained.
3. Press key 5 in the main menu (Calibration) and
follow the display instructions. Hold the pendulum
at 0-position and wait for one “beep”.
4. Hold the pendulum at 2 kp-position and wait for
one “beep”. Hold the pendulum at 4 kp-position
and wait for one “beep”. Move the pendulum to
the 6 kp position as told in the display. Hold it in
position and wait for two “beeps” shortly after
each other.
5. Lower the pendulum to the resting position
(0-marking). Calibration is done.
The calibration coefficient which has been calculated
by the computer is stored in the continuous memory.
Whenever power is applied to the ergometer, the latest
calibration value is restored to maintain memory. A
new calibration replaces previous values.
Generally, it is not necessary to recalibrate the
ergometer often. The coefficient is maintained even
when power is removed and the physical orientation
of the frame, within the limits of normal riding, has
no effect on the electrical calibration. Recalibration
should be preformed following any service, component
replacement, or transport of the unit or after setting
to default in the service menu (99).
A daily validation of the pendulum force sensor
should be preformed. If the procedure reveals an
error, recalibration may be necessary.
Monark 839 E

Calibration of pendulum weight
Although all Ergometers are calibrated at the factory
the user may wish to verify this by performing a
mechanical scale calibration. If so please do the
following.
Remove the cover from the flywheel. Loosen the
balancing spring from the brake belt. Check that the
0-index of the scale is in line with the index of the
pendulum weight. Adjust if needed. NB! Wait until
the flywheel is not moving any longer.
Attach a known weight, e.g. 4 kg (Art. No: 9000221) where the balancing spring was placed. Note:
The weight should not be lighter than 3 kg, due to the
possibility of inferior accuracy.
When correctly set, it should be possible to read this
weight from the corresponding place on the meter
panel.
Should there be a deviation, adjust the pendulum
to the correct position on the scale by means of the
adjusting weight. In order to change the position of
the adjusting weight, loosen the lock screw of the
weight.
Should the index of pendulum weight be too low,
move the adjusting weight upwards into the weight.
Should the index be too high, the adjusting weight is
moved downwards and locked in the new position.
This procedure is repeated until the correct reading
is achieved.

Testing with Ergomedic 839 E
The versatility of the 839 E Ergometer enables it to
be utilized in a variety of testing environments. The
precision and reproducibility of measurements made
with the ergometer in conjunction with the ease of
testing, allow it to be employed in clinical exercise
stress facilities, corporate fitness programs and health
clubs. The backgrounds of both the individuals being
tested and those administering the test may be vastly
different in these widely varying testing situations.
In general, whether in a clinical laboratory or a health
club, the subject may be exercised quite strenuously,
depending on workloads which have been selected. As
a precaution, it may be advisable, prior to beginning
an exercise protocol, that each subject consult with a
physician. Before testing, the operator should review
the entire protocol operation with the test subject,
explaining the work which will be required and the
duration of the procedure. A system of communicating
fatigue, chest pain or other abnormal physical response
to the exercise should be discussed.
Finally, the chestbelt should be applied and monitored
to check for proper heart rate operation. The baseline
heart rate may also be of assistance in determining
the nervousness of the test subject. The test subject
should exhibit a relatively stable resting heart rate
prior to starting the protocol.
Power calculation
1 rpm = 6 m on the flywheel brake surface.
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
(watt = rpm x kp)
The test subject 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 subject should
also refrain from smoking within an hour of the
testing period.
The test subject should be prepared for riding the
ergometer, including the selection of proper clothing
which neither interferes with the physical activity
nor endangers the health of the test subject. The test
subject may need some general education concerning
the pedalling of the ergometer. The saddle and the
handlebars should be adjusted for comfort and
proper mechanical distance. 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 to the bottom position.
The operation of the speed metronome and over/under
display should be reviewed. The maintenance of the
proper speed should be practiced at a low workload.

Heart rate (Telemetry system)
Subject supervision
The test subject’s heart rate can be monitored by
chestbelt telemetry system. The system with chestbelt
electrodes is standard equipment.
The ergometer performs automated tests virtually by
itself, requiring minimal intervention by the operator.
This allows the operator to pay careful attention to
the test subject without distraction. The response
to the exercise protocol can be accurately estimated
and appropriate action to assist the test subject, if
necessary, may be given. The rider is subjected to
considerable exercise in certain advanced protocol
stages. The effect on the test subject should not be
underestimated.
The chestbelt should be secured at a comfortable
tension around the mid section, just below the breast
muscle. Moisten the electrodes before use. Heart
rate monitoring, free from artifact, requires good
electrode contacts and adequate skin preparation.
Prior to placing the electrodes, the test subject’s
skin at the electrodes sites, should be cleaned with a
commercial skin prep solution. To make sure that you
have found the correct position the logo should have
been placed in the center of chest and also be readable
by another person. To enable a reliable contact with
pulse receiver on the bike the distance should be kept
below 100 cm. It is important to identify the chestbelt
with the pulse receiver by standing close to it before
beginning (max 60 cm, concerns Polar belts). After
the chestbelt is placed the heart rate will be displayed
and the heart will verify each beat. If the rpm bar is
set to show optical heart beat in the middle section
this will also verify each heart beat.
NOTE! Electromagnetic waves can interfere with the
telemetry system. Cellular phones are not allowed to
be used near the bike during test.
If the ergometer is to be used without a chestbelt note
that max heart alarm should be set in “off” position
so that external noise cannot cause a random max
pulse or higher. This switch is in “on” position by
default. If the heart rate exceeds the maximum level
set, the alarm will sound and the ergometer braking
force will decrease until the heart rate drops below
the alarm level.
16
During the testing, the general appearance and heart
rate may be the most crucial factors to monitor. The
testing should be stopped immediately if the test
subject reports chest pain, difficulty breathing, etc. A
system of prompt medical attention should be set up
prior to testing, in case of emergency.
The test subject may also show difficulty in regulating
the speed of the ergometer. The power will be properly
regulated regardless of the speed, assuming that the
protocol work type is not force and that the speed is
maintained above the pedal low setting (default is 30
rpm).
In addition, some test subjects may become sensitive
to the display on the terminal. If this is suspected, the
terminal may be removed from its cradle and located
out of view. Similarly, the pulse LED may disturb the
test subject and may be disabled.

Reviewing results
The maximum oxygen uptake is the standard
measurement of cardiopulmonary fitness. 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 subjects who are less
familiar with bicycle exercise and those individuals
who are less fit, are more likely be less efficient than
those who ride bicycles 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.
A relative fitness index can be obtained from the
following tables:

Operation interferences
It is normally considered that about 70 % of all shutdowns on small computers are caused by mains interferences,
i.e. at shot over voltage. These interferences can often be caused by different machinery, which is started or
stopped. The processor in the computer is then reacting incorrectly or is not working at all. The problems can be
solved by means of a mains interference protector, which is connected between the mains and the transformer.
Troubleshooting guide
Symptom
Probable Cause/Corrective Action
LED doesn’t light up.
No current in the outlet. Check the fuses.
Right trafo? Check so that the trafo information in section “Facts” is
in accordance with the trafo used.
No connection to PC.
Check cable.
Right COM port?
Drivers missing when using the USB-serial adaptor. CD with drivers is
included.
Is the right type cmd set?
Does not load work.
Check rpm (no force is applied if rpm is less than the pedal low ref.
Default 30 rpm)
Check calibration
No heart rate.
Check the chestbelt (battery). Wet the thumbs and place them on the
electrodes. A low clicking sound will appear near battery lid while you
click on the electrodes with one thumb.
Use another external HR monitor to check the belt.
Check that the chestbelt is positioned correctly on test person and
tight enough.
Check that the electrodes are wet, in some cases it is necessary to use
a contact gel or a mixture of water with a few drops of washing-up
liquid.
The level for HR signal can vary from person to person. Put chestbelt
on another known person who has a good pulse rendering.
Check for no loose cables or jack if you have a plug-in receiver. Use
another pulse receiver (pulse watch or test bike monitor) to check the
chestbelt.
Check that it is the correct receiver and that it is in the correct place. If
it has a round Polar-sticker it should be placed straight.
No rpm reading.
Check cable.
Unable to calibrate force.
Potentiometer belt may be slipping or broken. Replace if damaged.
Potentiometer misadjusted.
Reboot memory from service menu (99). Set default (3).
Uneven heart rate.
Use an external unit, for example a pulse watch, to check if it also
indicates irregular pulse. If this is the case, there is probably disturbance in the room. Magnetic fields from high voltage cables, elevators,
fluorescent tube etc can cause the disturbance. Other electronic equipment could be placed too close.
If irregular pulse remains we recommend measuring HR manually. If
HR still remains irregular at workload test person’s health needs to be
examined.
There is a click noise with every pedal revolution (increases with the weight).
The pedals are not tight. Tighten them or change pedals.
The crank is loose. Check, tighten.
The base bearing is loose. Contact your dealer for service.
Scratching sound is heard when pedalling.
Check that the carriage block is taken off and that none of the covers
is scratching.
There is a click noise and a squeak noise when Loosen the chain.

Service action:
• We recommend isopropyl alcohol to disinfect the
surface of the bike. Use a damp, but not wet cloth
to clean the surface you wish to disinfect.
• Clean and lubricate your Ergometer weekly.
• Periodically wipe the surface with a rust
preventative, especially when it has been cleaned
and the surface is dry. This is done to protect the
chrome and zinc parts as well as the painted parts
(4 times per year).
• Check that pedals are firmly tightened. If not, the
threading in the pedal arms will be damaged. Also
check that the pedal arms are firmly tightened on
the crank axle, tighten if necessary. When the
Ergometer is new it is important to tighten the
pedals after 5 hours of pedalling (4 times per
year).
• Check that the pedal crank is secure to the crank
axle (4 times per year).
• Be sure that the pedals are moving smoothly, and
that the pedal axle is clear of dirt and fibres (4
times per year).
• When cleaning and lubricating be sure to check
that all screws and nuts are properly tightened
(twice a year).
• Check that the chain is snug and there is no play
in the pedal crank (twice a year).
• Check that pedals, chain and freewheel sprocket
are lubricated (2 times per year).
• Be sure that the brake belt does not show significant
signs of wear (twice a year).
• Check that the handlebars and seat adjustment
screws are lubricated (twice a year).
• Be sure that all moving parts, crank and flywheel
are working normal and that no abnormal play
or sound excsists. I.e. play in bearings causes fast
wearing and with that follows a highly reduced
lifetime.
• Check that the flywheel is placed in the center and
with plane rotation.
Monark 839 E
Batteries
If the meter is battery-operated, the batteries are in
a separate package at delivery. If the storing time
has been long the battery power can be too low to
make the computer act correctly. Batteries must be
changed.
Crank bearing
The crank bearing is greased and normally requires
no supplementary lubrication. If a problem arises,
please contact your Monark dealer.
Flywheel bearing
The bearings in the flywheel are greased and do not
normally require maintenance. If a problem arises,
please contact your Monark dealer.
Transport
At transport the brake belt should be tightened to
prevent it from falling off the flywheel.
Replacement of brake belt
To replace the brake belt remove covers if necessary.
Make sure that the belt is loose.
Alt. 1: To loosen the belt on pendulum bikes with a
motor, turn the power on and move the pendulum
to 4 kp. Hold it there until the brake belt is loose.
Observe how the belt is connected. Take it apart and
remove it from the bike. Attach the new brake belt
and assemble the bike in reverse order.
Alt. 2: To loosen the brake cord on cycles with a weight
basket set the basket to its upper position. Loosen the
lock washer that is holding the cord and remove it
from the tension center. Loosen or cut off the knot on
the other end of the cord and then remove the whole
cord from the bike. When assembling a new brake
cord, first enter one end into the hole in the tension
center, tie a knot and let the knot fall into the bigger
part of the hole. Lock the end of the cord with the
lock washer.
Alt. 3: To loosen the belt on other bikes remove all
possible tension. Observe how the belt is connected.
Take it apart and remove it from the bike. Attach
the new brake belt and assemble the bike in reverse
order.
NOTE: When replacing the brake belt it is
recommended to clean the brake surface. See ”Brake
belt contact surface”.
Brake belt contact surface
Deposits of dirt on the brake belt and on the contact
surface may cause the unit to operate unevenly and will
also wear down the brake belt. The contact surface of
the flywheel should be smoothed with fine sandpaper
and any dust removed with a clean dry cloth.
Remove any covers and loosen the tension on the
brake belt. Smoothe with fine sandpaper. This is
easier to perform if a second individual cautiously
and carefully pedals the cycle.
Irregularities on the brake belt contact surface are
removed by means of a fine sandpaper or an abrasive
cloth. Otherwise unnecessary wear on the brake belt
may occur and the unit can become noisy.
Always keep the brake belt contact surface clean and
dry. No lubricant should be used. We recommend
replacing the brake belt when cleaning the contact
surface. In regard to assembly and adjustment of the
brake belt, see ”Replacement of brake belt”.

Chain 1/2“ x 1/8“
It is strongly recommended to keep the chain clean.
Dirt build-up on the chain will cause excess wear. A
chain lubricant and solvent for normal road bikes
may be used.
Check the lubrication and tension of the chain at
regular intervals. In the middle of its free length the
chain should have a minimum play(3) of 10 mm (1/4
inch). See fig: Chain adjustments. When the play in the
chain is about 20 mm (3/4 inch) it must be tightened
otherwise it will cause abnormal wear of the chain and
chainwheels. Because of this it is always recommended
to keep the chain play as little as possible. Loosen the
hub nut(2) on both sides and tense the chain with the
chain adjuster(1) when needed.

When the chain has become so long that it can no
longer be tightened with the chain adjusters it is worn
out and should be replaced with a new one.
Fig: Chain adjustments
1) Chain adjuster
2) Hub nut
3) Chain play
To adjust or replace the chain remove frame covers if
necessary.
To adjust the chain the hub nuts(2) should be
loosened. Loosening or tightening the nuts on the
chain adjusters(1) will then move the hub and axle
forward or backward. Adjust according to above
recommendation. Then tighten the nuts on the hub
axle again. See fig: Chain adjustments.
To replace the chain, loosen the chain adjuster as much
as possible. Dismantle the chain lock(6) and remove
the chain. Put on a new chain and assemble the chain
lock. The spring of the chain lock should be assembled
with the closed end in the movement direction(5) of
the chain. Use a pair of tongs for dismantling and
assembling the spring(4). See fig: Chain replacement.
NOTE: At assembly, the flywheel has to be parallel
with the centerline of the frame otherwise the chain
and chain wheels make a lot of noise and wear out
rapidly.
Adjust chain adjusters to allow chain play according
to above. Tighten hub nuts firmly. Replace frame
covers.

Freewheel sprocket
When replacing the freewheel sprocket remove frame
covers if necessary. Dismantle the chain as described
in part ”Chain 1/2” x 1/8” ”.
Loosen the axle nuts and lift off the flywheel. Remove
the axle nut, washer, chain adjuster and spacer on the
freewheel side. Place the special remover (Art. No:
9100-14) in the adaptor and place the spacer and axle
nut outside. See fig: Special remover. Replace sprocketadaptor and assemble the new parts in reverse order
according to the above.
NOTE: Do not tighten the axle nut completely. It
must be possible to loosen the adaptor-sprocket half
a turn.
The sprocket should be lubricated with a few drops of
oil once a year. Tilt the cycle to make it easier for the
oil to reach the bearing. See fig: Lubrication.
