Trigno System Components Wireless EMG Sensor Each Trigno Sensor is equipped with the following features: • transmission range of 20m • inter-sensor latency < 500us • self-contained rechargeable battery • EMG signal bandwidth 20- 450 Hz • EMG signal sampling rate of 4000 samples/sec •...
• power LED Figure 2. Trigno Base Station Power Supply Trigno Systems are equipped with an isolated medical grade power supply. The green power LED on the base station will illuminate when power is connected to the Base Station. The power supply is provided with interchangeable country-specific plug adapters.
Refer to Appendix I for further details. No PC isolation is required for operation on a battery-powered laptop. Sensor Adhesive Skin Interfaces Trigno sensors can be affixed to the body with convenient dou- ble-sided adhesive interfaces. Ensure that the sensor site is cleaned with isopropyl alcohol immediately prior to application.
Getting Started with the Trigno System Powering the Base Station Connect the Trigno power supply to the circular DC jack located on the side of the Base Station. Energize the power supply by connecting it to a Mains outlet or to an isolation transformer.
Define a Hardware Configuration and an appropri- ate Test as described in the EMGworks User’s Guide. Note that the sampling rate for Trigno Sensors is fixed 4000 samples/sec for EMG data and 296 samples/sec for accelerometer data. When the Trigno Test is initiated, the Trigno System Console will appear in a separate window.
Using the Wireless EMG Sensors Orienting the EMG Sensors on the Skin The Trigno EMG Sensor is fitted with 4 silver bar contacts for detecting the EMG signal at the skin surface. It is crucial that the orientation of these bars be perpendicular to the muscle fibers for maximum signal detection.
Using the Delsys Adhesive Sensor Interface The Adhesive Sensor Interfaces use medical-grade adhesive spe- cifically designed for dermatological applications. Usage of the interface promotes a high quality electrical connection between the sensor bars and the skin, minimizing motion artifacts and the ill-effects of line interference.
Recharging Base Station The Trigno System is designed to provide years of reliable ser- vice when proper care is followed. While the Base Station enclo- sure is made of durable plastic, the following points should be kept in mind when using and handling it: •...

• The Base Station can be easily cleaned with a damp cloth and mild detergent or with a 70% solution of isopropyl alcohol. DO NOT IMMERSE THE BASE IN LIQUID. • The units are not shockproof and should not be dropped or be subjected to excessive forces or accelerations.
