Bagnoli™-8 EMG System - Specifications

All electrodes and systems are tested and calibrated before shipment to ensure that manufacturing specifications have been met. Performance according to specifications is guaranteed for environments devoid of noise sources. Examples of common noise sources include electric motors (such as those found on treadmills and fans) and high current power supplies. Performance according to specifications cannot be guaranteed if DelSys devices are used in conjunction with other equipment that has not been reviewed and approved by DelSys Inc. Examples include proprietary A/D cards and electric exercise equipment.
