Corival
To 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.
Overview

Highlights
Reliable and reproducible stress tests
The experience of professionals who calibrate many ergometers has learned that the Lode ergometers are the most reliable over the complete workload and rpm range and still within specifications even after many years of intensive use.
Stability
Since athletes are getting more and more powerful and testing more extreme, the ergometer is designed for high workloads up to 2500 watt. Even the strongest and most powerful athletes will experience a stable and comfortable basis.
High standards
Lode is a social and environmental responsible company.
All Lode products are RoHS/WEE compliant.
Furthermore, Lode is ISO 9001:2003, ISO 13485:2008, FDA 510K, IEC 60601-1 and DIN 13405 certified.
Rotatable handlebar
The handlebar can be rotated 360 degrees and is constructed in such way that the test subject can be installed comfortably at every seating height. This design makes a height adjustable handlebar redundant.
Features
Compatible with ECG and pulmonary devices
The Lode ergometers have both analog and digital interfaces and can be controlled easily by all known stress ECG and pulmonary devices available in the world. This is one of the reasons why the Lode ergometers are very popular worldwide.
7 Watt start-up load
Extreme low start up load
The extreme low start-up load of 7 watts and the adjustability in small steps of 1 watt make this ergometer perfectly suitable for many different applications. The standard control unit shows multiple ergometry parameters and you can determine your specific default setting and start-up menu.
Silent Design
Low noise
Due to accurate manufacturing and the careful choice of materials the product has an extremely low noise level
Accurate over a long period of time
The Lode ergometers have an electro-magnetic braking mechanism of Lanooy (eddy current). The biggest advantage of this braking system compared to a friction braking system is that it is more accurate. Moreover, friction braking systems have more wearing parts.
1 Watt adjustment
Small adjustment steps
The workload of the Lode ergometers is adjustable in steps of only 1 watt. Depending on your wishes, the test operator or the test subject can adjust the workload. The steps of 1 watt are possible in the manual mode as well as within protocols.
Versatile controls
Additional features with PCU
Besides the possibility to program 24 protocols easily, this control unit offers the following features:
- better monitoring because of the additional and larger display
- a perfect combination with BPM
- possibility to measure SpO2
Low step-up
Easy step-through
The Corival has a comfortable step-through: a must for people who are not so mobile a must!
RS232 connectivity
RS232 ports enable connectivity to most ECG and ergospirometry devices as well as PC's

FAQ

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 support section 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.
