Portable Calibrator Versa
Easy and efficient calibration of ergometers
The Calibrator Ultra is an easy to set up and very accurate portable calibration station. The calibration station is controlled by a PC or laptop. With this station it is possible to control or calibrate all existing ergometers accurately. The Lode Calibrator is mounted on the axis of the ergometer. This system is approved by an independent institute, and is used by calibration institutes all over the world since 1993. Calibrations can be done up to 750 watt. Due to the possibilities you create when using a normal PC to calibrate the calibrator you can print a calibration report for your customer and/or create your own database of calibration data. The Calibrator Ultra is the essential tool for professionally and efficiently servicing ergometers.
The Calibrator Versa is the next development in professional portable calibration equipment, coming from a pedigree of 2 decades of calibration devices supporting accurate ergometry.
Please note, specifications at 110 V are different than at 230 V.

FAQ
A static calibration is used for some ergometers to check the assumed linear relationship between 2 workload points with use of weights. This type of calibration is not accurate because the driving gear is not taken into account and the relationship is not totally linear at higher and lower workloads. Historically mechanical ergometers are calibrated by this method the accuracy is shifting a lot between tests because the belt-length (mechanical braking part) is influenced by heatening. Static calibration is not fulfilling any relevant norm. Dynamic calibration is performed by a service engineer with a calibrator. The ergometer is calibrated at the axis in the total workload and rpm range (instead of 2 points without any movement of the driving gear). The data can be compared with the initial calibration report from the factory to check drifting in time. A calibration report is printed for the customer and stored by the service engineer. Dynamic calibration performed with a Lode calibrator is accurate and fulfills all relevant norms and certifications.
Yes, Due to the fact that the scientific research on the spread of Covid-19 is not yet conclusive Lode recommends to disinfect and clean all Lode products and their accessories (cuffs, heart rate belts, SpO2 sensors, handgrips/rails, touchscreens etc) that are in contact with the patient and or the medical personnel with a standard disinfectant as used in the hospital before and after every patient, with attention and care!
Since these agents are sometimes aggressive it might be advisable to check the effect on sensitive surfaces, like cushioning on non-visible areas. Lode will not take responsibility for discoloration due to these agents.
