Product Information
Thank you for choosing a test cycle from
Monark!
The Monark 928 E G3 / 928 G3r is designed to, in a
simple way, be used for submaximal exercise test and
make calculations of the maximum oxygen uptake.
The bike can also be used for normal exercise.
Ergometer 928 G3 is equipped with a meter that
is available in two versions - 928 G3 and 928 G3r
928 G3 has 6 different programs and 928 G3r has
two programs. The cycle can also be connected to
a computer with software for testing (software is
available for free download from our website: www.
monarkexercise.se).
The G3 models also have a new and more powerful
engine for faster power control.
For more detailed description of the meter's functions,
see the section "Display Description".
All 928 G3 and 928 G3r are calibrated at the factory.
This means that you can begin to use the ergometer
directly after assembly. However, if the user wishes to
verify the scale calibration please read the instruction
for ” Calibration” in this manual.

Operating Instruction
Workload adjustment
A change of the workload is done either by changing
the pedal speed or by pressing (+/-) button on the
meter to increase or decrease the brake belt tension
on the flywheel. See Fig: Workload adjustment and
connections.
Power measurement
The cycle is designed to measure the power on the
flywheel, because tests/protocols are made for it (for
example Åstand’s and YMCA).
Power Connection
The bike is designed to be used with the AC adaptor
which is included with the bike. Connects (3) to the
bike as shown in Fig: Adjustments.
Fig: Adjustments
1) Locking knob, saddle
2) Locking handle, handlebar
3) Connection unit
Fig: Workload adjustment and connections
1) USB
2) Workload (+/-)
Connection to an external unit
When the USB connector is inserted or when the meter
detects a connected computer, you will hear a quick
double beep. An icon for the USB lights in the display.
Otherwise, the meter will turn off except rpm and HR.
When the meter is connected to a computer, it turns to
passive mode. No buttons are active except HEART
button (to pairing the display and chest belt).
The socket for the USB connector (1) is shown in Fig:
Workload adjustment and connections.
Calories
There have been different theories on how to calculate
this, since it depends on several factors and this means
that it can only be seen as an estimate.
As a standard calculation when we display calories
on our calibrated bikes we use: 1 minute with 100W
gives 7 kcal. It is easy to convert watts to calories if it
was on the flywheel (the formula is 1W=0,2388x10-3
kcal/s with four decimals), but when you normally
show calories you want to show the total amount of
calories your body has used during your training, not
only the calories "burnt" on the flywheel.
We have chosen the formula given above that we
think complies with the results given for a standard
cycle position.
Cycle adjustments
When adjusting the seat height:
Turn the knob (1) on the seat post and pull it out.
Adjust the height and lock the knob again.
Handlebar settings
To adjust the handlebar angle loosen the quick release
lever (2). See Fig: Adjustments.

Monark 928 G3 / 928 G3r 7
The user's heart rate can be measured with a chest
belt that senses the electronic output of the heart.
Chest belt ANT+ is supplied as standard.
Fuss-free HR measurement requires that the belt is
correctly placed. Make sure that your skin is clean
where the chest belt should be placed. When it is
correctly fitted the logo on the belt will be central and
readable, outward and upright, by another person.
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: Moistening the
electrodes.
NOTE! Electromagnetic waves can interfere with the
telemetry system. Cellular phones are not allowed to
be used near the bike during test.
Pulse standard (chest belts)
The following pulse standard / chest belts can be
used:
Standard, uncoded 5K chest belts (5-5.6 kHz)•
Chest belts with ANT+•
Short range ANT+: 0.6-0.8 m (24"-31 ½")
Long range ANT+: 4-5 m (13-16 ft)
Range 5K: 0.8 m (31 ½")
Pairing display and chest belt
Normally the display connects to the first ANT+ chest
belt in "short range" and shows the heart rate until
the chest belt is outside the "long range". If there is no
ANT+ chest belt but a 5K chest belt in "short range",
the heart rate from the 5K chest belt is displayed until
the signal is lost.
ANT+ is prioritized and the first choice of the display.
5K is discriminated, but after 30 seconds with only
5K the display is locked to this chest belt as long as
you do not lose the signal.
Pulse function
Monark Exercise AB recommend that you
use an ANT+ chest belt for best function.

Fig: Metronome
Here you can make individual adjustments to
optimize the bike for your needs on first use and when
needed.
Cycle constant
The cycle constant is as default set to 1.00. Change
using the (+/-) button.
When the cycle constant is set to 1.00 the power is
measured at the flywheel. This is used in Astrand test,
YMCA etc.
When the cycle constant is set to 1.05 the power
is measured at the crank. This is often used on
electronically-braked bikes.
Metronome cadence
Metronome diodes show pedalling revolutions (rpm)
relative to the set reference value. The metronome is
located at the back of the meter. The default value is 60
and can be adjusted with (+/-) button. The green LED
in the middle flashes twice for each pedal revolution
which helps to keep the right pedal cadence, see Fig:
Display and Fig: Metronome.
The meter can be rotated so that the rider does not
see the values in the display, but only sees the flashing
diodes (in order to keep the right pedal cadence).
If START STOP is pressed, or if no
button is pressed for 20 seconds (in
all steps), the changes are saved and
the display returns to normal with
the new settings active.

Steady State (SS) HR is used only in Astrand program.
SS is checked by comparing the mean value of HR
during the period 4:45 to 05:00, and the mean time
between 5:45 to 6:00. If the difference between these
two values is the same or less HR is counted in SS.

Scale - zero adjustment
Connect power to the bike. Loosen possible tension
in the brake belt by moving the indicator to 0.5 kp.
Hold it there until the belt feels loose. Then move the
indicator to 0 again. Now check if the indicator is
aligned with the 0-index on the scale.
If adjustment is needed, loosen the locknut(1) and
then change the position of the scale board, so that it
will have its 0-index in line with the pointer. Tighten
the lock nut after the adjustment. See Fig: Scale
adjustment.

Mechanical calibration
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:
First, follow the steps in the "Scale - zero•
adjustment”. Adjust the pendulum if necessary.
Loosen the calibration hook from the hook•
bracket, see Fig: Calibration mode.
A checked and approved weight(4), 4 kg (Art. No:•
9000-211), attached to the calibration hook (5),
see Fig: Calibration. Note! The calibration hook
should always be left in the hook control.
If the calibration is correct, the indicator should•
point to 4 kp on the scale.
Lift off the weight and replace the calibration•
hook in the hook bracket, see Fig: Normal mode.
Note! The hook must be inserted in the holder
during operation.
If there is a deviation, adjust the pendulum to the right
position on the scale by adjusting the weight inside
the pendulum (2). To do this the left cover must be
removed.
To adjust the position of the weight, the locking screw,
in the center of the pendulum(3), must be loosened.
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.
Check the calibration of the pendulum weight once a
year or when needed.

METS
During the test METS and l/min are continuously
counted and displayed.
Calculation
METS values are displayed and calculated from the
current workload. The two VO2values displayed
during the test continuously calculate the average
value for 5 seconds.
The formula used (values from ASTRAND original
table) to calculate VO2at different workloads is:
0.2333 ... l / kpm = 0.01428 L / W (2.8 l / min at 1200
kpm)
This is according to Astrand's table between 150 W
and 300 W, and a good approximation for 15-700 W
and a cadence of about 50-65 rpm.

Steady State (SS) is checked by comparing the average
HR during the period 4:45 to 5:00 with the average
HR during the period 5:45 to 6:00. If the difference
between these two average values is the same or less
considered SS.
When the test is completed the results are calculated
and shown directly in the display.
You can stop the test manually after six minutes by
pressing START STOP even if SS is not active (an
error message is shown). The result is calculated and
displayed.

The end pulse is too low and outside
the Astrand tables so no results can be
calculated.
The end pulse is too high and outside

(Except 928 G3r) The test is automatic after it has been started. Two
or three levels (6 or 9 minutes) run automatically
according to the table on the next page.
After six or nine minutes the test stops automatically
and the YMCA will stop flashing. The results are
shown in the display.
You can stop the test manually after two levels (6
minutes) by pressing START STOP and the results are
calculated if the values are within the tables.
If the test values are outside tables so that no results
can be given, you will hear a long beep and an error
message appears.
