Monark Exercise AB

Monark has 100 years’ experience of bicycle production. The Monark tradition has yielded know-how, experience, and a real feel for the product and quality. Since the early 1900s, Monark’s cycles have been living proof of precision, reliability, strength and service. Those are the reasons why we are now the world leader in cycle ergometers and the market leader in Scandinavia in transport cycles.

We manufacture, develop and market ergometers and exercise bikes, transport bikes and specialized bicycles. Our largest customer groups are within health care, sports medicine, public authorities, industry and postal services.

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

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.

Sleep mode

Sleep mode is activated after 10 minutes if you do not press any button or if no rpm is recorded.

All settings are saved, but the personal settings are erased (to protect your personal privacy).

The meter wakes up when you press any button or if rpm is recorded. The meter goes directly to 'Quick start' (see separate section).

We recommend to use only the AC adaptor when using the bike. Without the AC adaptor, there will be no workload control and display alarm is activated.

Calibration and basic settings are saved even when the power fails.

(The display can be powered by batteries, 4x1.5V, R14, but only when you make the basic settings.)

If the values for rpm and watt start ﬂashing during use, the set workload requires higher brake power than 7 kp. To solve this, increase the rpm or decrease the set workload.

Press ENTER to enter the menu for "Personal settings"

Usually you are asked to set the personal data needed when you start a program or a test. This data can also be set before, during e.g. "Warm up" in Training program with this function.

The settings are saved until the meter goes into sleep mode. When the display wakes up the personal settings are changed to default values (this is to protect your personal privacy).

Alternative power / force display

The meter displays power in watts (default). If you want to display the power in kpm / min instead, press the HEART button for 5 seconds. Then you can switch between WATT, KPM / MIN and current kpvalue using the (+/-) button. Press ENTER or wait 10 seconds to conﬁrm and exit the setting.

NOTE! Even if you select kp as unit, it is power in watts which

is set in the background when you press (+/-) button. The displayed kpm / min is a simpliﬁed calculation

(1 kp = 10 N) according to Astrand's tables.

(Although the displayed kp value is correct and not rounded as above. For all calculations in the display the exact value is used, 1 kp = 9.80665 N)

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.
