Part number: 906900
Can be controlled by all known Cardio Pulmonary Exercise devices

The Corival is one of the most popular ergometers worldwide. The low start-up load of 7 Watt is unique. The Corival can be controlled easily by all known stress ECG and pulmonary devices in the world. The Corival has an eddy current electro-magnetic braking mechanism. The biggest advantage of this system is the accuracy which is one of the most important Lode principles. With this ergometer, the stress tests performed are reliable and reproducible. The workload is adjustable in a range of 7 to 1000 watt. Moreover, the noise level is reduced to a minimum. Easy transportation of the device is possible by a simple retractable wheel.

Successor: Corival cpet



Q - In what range are the handlebars of the Corival and Excalibur adjustable?

The Corival handlebar is adjustable within 0-360 degrees.
The Excalibur Sport's handlebar is adjustable in both vertical (465- 855 mm) and horizontal (229- 600 mm) direction.

Q - Is it possibe to estimate the travelled distance?

This is possible for all ergometers from 2004 on. Since 2009 it is possible to create yourn own calculation by using the adjustable resistance. Note: both pedalling speed and workload are taken into account by estimating the travelled distance.

Q - What is Eccentric ergometry

During Eccentric or negative ergometry you have to resist against a workload produced by a motor instead of an electromagnet, see article prof. Folgering: Effects of positive and negative exercise on ventilatory CO2 sensitivity.

Q - Is it possible to control the Lode ergometers and treadmills with external equipment

Yes, you can find interface sheets for most common devices on the website at the "service" tab of this website. If your device is not present you can ask us to support you. In most cases we can quickly provide you with a solution.

Q - What is the principle of the Heart rate option?

The HR option is the well known Polar* heart rate receiver. The receiver is integrated in the software of the controller. The test subject has to wear the heart rate belt around the chest. The receiver is placed in front of the test subject (or integrated in the controller in case of a Corival) and the HR data will be displayed on the controller of the ergometer

Q - What is heart rate controlled cycling / protocol?

During heartrate controlled cycling or running, you can determine a maximum heartrate limit. When this limit is reached, the ergometer/treadmill will adjust the workload/speed so the heartrate will stay more or less stable. You can perform a HR controlled test with the standard controller. You can program HR controlled protocols with the controller of the Valiant, Corival, Angio and Excalibur (more heartrate limits in one protocol (per step)), and the LEM (multi control) software module.

Q - What is the 0 Watt start up system?

The 0-Watt start-up system is an option for the Corival and Excalibur ergometers. It offers the opportunity to start the ergometer at a preset pedal speed (30-80 rpm). The number of revolutions is increased from 0 to the desired rpm by means of a motor drive. With this option there is no energy-loss for the test subject due to the start-up phase. The motor has to be built-in in the ergometer during manufacturing. Example: before starting the test the ergometer must be set at the lowest workload (7 watt), or a protocol must be selected with a first step of 7 Watt (max 10 Watt). When pushing the 0-watt button, the number of revolutions is increased to the required pedal speed. Release the button and the ergometer will have a workload of 7 watt. The test subject does not have to overcome the initial resistance of the braking mechanism and can start the test with the lowest workload at the required rpm in the normal rpm-independent mode.

Q - Is it possible to turn the display around so it is facing the physician?

Yes, before purchasing, you can order or it can be changed by a service engineer.

Q - Is the SpO2 option compatible with LCRM?

Yes the SpO2 results are visible during the rehab session.

Q - Can I change the contrast of the display on my Lode bicycle ergometer?

Your Lode ergometer is standard supplied with one display. The contrast of this display is factory set and can adjusted by qualified service personal only. If your ergometer is supplied with a programmable option the contrast of this display can be set as follows: go to SYSTEM PARAMETERS select SETTINGS go to CONTRAST. Change the visability according your wishes and save the changes.

Q - What is the Q factor of the Lode ergometers?

The Q factor of a bicycle ergometer is the distance from crank to crank. For the Excalibur the Q factor is simular to a racing bike meaning 147mm (+/- 3 mm).
The Q factor of the other ergometers is a little bit bigger (like a city bike), for the Corival this is 180 mm.

Q - Can I use a RS232 to USB converter to connect an ergometer?

Yes you can. Make sure the chipset used in the converter is from FTDI to have good data acquisition.
