Page 15: Basic Operations
Basic Operations Charging the Trigno Sensors Connect the Trigno power supply to the circular DC jack located on the side of the Recharge Station. Energize the power supply by connecting it to a Mains outlet. Be sure to use the appropriate plug adapter for your location. -
Page 16: Charging The Personal Monitor
Charging the Personal Monitor Connect the SC-P07 power supply to the DC jack located on the bottom side of the device. Energize the power supply by connecting it to a Mains outlet using an appropriate IEC320 power cord. Alter- natively the Personal Monitor can be charged via the USB port by connecting it to a PC. -

empty battery is expected (if discharging). As different functions are performed on the TPM, the rate of battery depletion will change so too will the charge level estimates. Battery time to empty estimates update approximately once every minute. When connected to a PC, EMGworks will also show the charge state of the TPM. -

Page 19: Getting Started
Getting Started To use the Trigno Personal Monitor, it must be first connected to a PC with EMGworks in order to create a data collection protocol, and load it onboard. Data can then be collected on the Personal Monitor which communicates with up to 16 wireless sensors (and the optional GPS module). - Page 20 Figure 14: Connecting the TPM to a USB port. Choose “Start Recording” to automatically launch EMGworks. If this dialog does not appear, launch “EMGworks Acquisition” from the Start menu or desktop. As EMGworks is launching, the following dialog will be displayed: Figure 15: Initializing the TPM with EMGworks software.

the device if it remains idle for the duration specified. Keep Sensors On: This feature will ensure that the wireless sen- sors remain turned on even when idle. When this feature is disen- gaged, the wireless sensors will turn off after 5 minutes of inactivity. Time Format: This option specifies whether to display the time in 12h or 24h format. -
Page 29: Log File (Main Menu)
Only a limited range of adjustment is allowed, to accommodate time zone differences from coordinated universal time. Since the local time is updated by EMGworks, daylight savings time can be automat- ically corrected by connecting to a PC and launching EMGworks. In the absence of a PC, daylight savings time may be manually adjusted directly on the device. -
Page 30: Retrieving Log File
Figure 29: Viewing the Log File from the Main Menu. Retrieving Log File The log file can be retrieved through EMGworks. To do this, launch EMGworks and open or create a protocol that uses the TPM. Click “Retrieve Device Log” from the A/D Settings pane under the Hard- ware node in the configuration tree. -
Page 31: Resetting The Device
Resetting the Device Initialization If the battery is fully depleted, initial configuration is needed to re- store device settings. To perform this configuration, plug the USB cable into any PC with EMGworks installed and launch EMGworks. When EMGworks is closed, the device will be fully configured. Figure 31: Initializing the TPM with EMGworks. -
Page 32: Reformatting The Data Partition
Reformatting the Data Partition In general, it is not necessary to reformat the data memory (partition) on the device, however, under particular circumstances this partition may become corrupt (for example if the device is disconnected while a data file is being read), and reformatting will be necessary. EMGworks offers an option to reformat the data partition, and it will make a best effort to restore the files stored on the data partition to the device after the reformat is completed. -
Page 33: Using The Wireless Emg Sensors
Using the Wireless EMG Sensors Orienting the Sensors on the Skin Trigno EMG Sensors are 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. -

connection between the sensor bars and the skin, minimizing mo- tion artifacts and the ill-effects of line interference. To ensure a strong bond with the skin, it is advised to remove excessive hair and wipe the skin area and the EMG Sensor with isopropyl alcohol to remove oils and surface residues. -

2. Complete the pairing process by depressing the desired sensor but- ton for a minimum of 3 seconds. Successful pairing will result in 3 green LED flashes on the sensor, and a confirmational message in the software. Figure 35: Pushing the sensor button to complete the Trigno systems are shipped with all sensors appropriately paired. -
Page 36: Smart Sensors
Smart Sensors After pairing, the association of sensors to the TPM is retained for all future uses. Any configuration in EMGworks can be made to reflect the last paired set of sensors by clicking the “Refresh Smart Sensors” button in the “Add Sensors” pane in EMGworks. When data collec- tion starts, the software will verify that the sensors currently commu- nicating match those used in the configuration. -
Page 37: Data Streaming
1) Data Streaming This is the typical data transmission state, where a sensor is commu- nicating with the TPM receiver and all data packets are being prop- erly received. This state is indicated by a constant green blink every second. 2) Receiver Scanning This state indicates that the sensor is not transmitting data to the re- ceiving unit, and more specifically not receiving any information from... -
Page 38: Mains Isolation
Appendix I Mains Isolation The Trigno Personal Monitor is provided with a Medical Grade iso- lated power supply which is compliant with IEC60601 series of har- monized standards for Medical Devices. However, full compliance with IEC60601-1 Basic Safety for Medical Devices requires that the PC operating the software be isolated as well.
