• 1 quattro user manual. END USER Quattro allows non-invasive recording sEMG detected by superficial electrodes. The end user must be familiar with the technique and received a proper training in EMG detection and interpretation. Contraindications Quattro has no particular contraindications when used jointly with personal computers, provided that all the electrical devices connected to it comply with safety rules and standards concerning grounding and leakage currents. -
Page 7: Safety Cautions And Other Warnings
Contact the manufacturer immediately if extraneous materials permeate into the device (liquids, powders, etc.). In case of hard shocks suffered by the quattro (like a drop to the floor, etc.), verify that no crack or any other kind of damage of the box resulted from the shock. -

- November 2017 • The connection between quattro and other electrical devices must be done in compliance with the European standard EN 60601-1-1 on medical devices. • The use of the quattro is restricted to skilled personnel. -
Page 9: Technical Specifications
TECHNICAL SPECIFICATIONS Quattro is a battery powered and galvanically insulated device designed to guarantee a high safety level for the patient and the operator in all operating conditions. The galvanic insulation separates the circuitry connected to the patient from the circuitry connected to external non-medical devices, such as the PC used for data acquisition. - Page 10 - November 2017 Quattro technical specifications are shown in Table 6.2. EMG channels Number of channels Gain 150 V/V Low pass filter 500 Hz High pass filter 10 Hz Noise level referred to input < 2 V >...

Refer to section 8.3 for additional details about the available adapters. A good procedure is to connect the adapters to the input jacks of quattro when the device is off. No risk for the patient or for the device are known when connecting and removing the adapter and the quattro is on, but big artefact are associated to the connection and disconnection of the adapters on all four channels. -

Analog Out connector The four EMG signals amplified and filtered from quattro are also available on this output connector. The signals are internally sampled for the data transfer to USB or Bluetooth. The digitalized data cross the insulation barrier and is then converted back to analog signals by means of an internal D/A converter. -
Page 15: Use Of Quattro
Bluetooth Interface To use the Bluetooth interface, it is first of all necessary to pair a PC (with OT BioLab installed) to the quattro. The pairing process is a standard process for Bluetooth devices that require a manual intervention to give consent at the interface between two particular devices. -

The other stages into the quattro allow to amplify and filter the EMG signals with a fixed gain of 150 V/V and bandwidth between 10 Hz and 500 Hz (filters respectively of the second and fifth order). - Page 17 - November 2017 ADx5JB This adapter allows the connection of electrode with 1.5 touchproof banana connectors. Figure 8.1 shows the adapter. FIG. 8.1: The ADx5JB adapter ADx5JC This adapter allows the connection of electrode concentric connectors. Figure 8.2 shows the adapter.
