Getting Started with the Personal Monitor
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 locations (Figure XX). Ensure that the Trigno sen-
sors are properly tted in the recharge pockets. e sensor LEDs will
illuminate to amber during charging and green when charge is com-
plete. e recharge unit will periodically check sensors and apply a
top-o charge to ensure that the battery kept at full capacity during
extended periods of storage, as long as power is connected.
Charging the Personal Monitor
Connect the Personal Monitor power supply to the DC jack locat-
ed on the bottom side of the device. Energize the power supply by
connecting it to a Mains outlet. Be sure to use the appropriate plug
adapter for your locations (Figure XX). Alternatively the Personal
Monitor can be charged via the USB port, by connecting it to a host
device.

Setting the Time
In order to guarantee data integrity and
proper le synchronization with EMG-
works, it is fundamentallly important
that the Personal Monitor retain accu-
rate time settings during operation. e
internal clock is automallicatly synchro-
nized by EMGworks when the device is
connected to a PC. In cases where ac-
cess to a PC is restricted, it is possible
to manually set the time by selecting the
“Set Clock” option from the Menu op-
tions.

Orienting the Sensors on the Skin
Trigno EMGSensorsaretted with4 silverbarcontactsfordetectinUg
the EMG signal at the skin surface. It is crucial that the orientation of
these bars be perpendicular to the muscle bers for maximum signal
detection. e top of the sensor is shaped with an arrow to aid in the
determination of this orientation. e arrow should be placed parallel
to the muscle bers underneath the sensor. e sensor should also be
placed in the center of the muscle belly away from tendons and the
edge of the muscle. e sensor is easily attached to the skin using the

bers. Align the sensor’s arrow with the direction of the underlying muscle
bers.
Prior to axing the EMG sensor on the surface of the skin, the sensor
site must be properly cleaned to remove dry dermis and any skin oils.
Wiping the skin prior to sensor application is critical. If excessive hair
is present, it will also be necessary to shave the site. In cases where the
skin is excessively dry, it may be useful to dislodge dry skin cells by
dabbing the site with medical tape. e dry cells will attach the tape’s
adhesive when it is removed. Be sure to wipe with isopropyl alcohol
to remove any adhesive residue that may remain.
Cleaning the Sensor Site
Applying the Sensor Interface
Trigno System are supplied with specially-designed adhesive inter-
faces to simplify sensor attachment. ese interfaces are cut from
double-sided medical grade adhesive approved for dermatological
applications. Usage of the interface promotes a high quality electri-
cal connection between the sensor bars and the skin, minimizing mo-

16
tion artifacts and the ill-eects 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. Allow the skin to dry completely before apply-
ing the interfaces.
Adhesive Sensor Interfaces are for single use only.
Immediately discontinue use if skin irritation or discomfort oc-
curs. All Adhesive Sensor Interfaces and Reference Electrodes are
for single use only. Discard aer using. Reseal storage bag to main-
tain freshnes
Sensor Pairing
Trigno sensors communicate with a custom wireless protocol that
links each sensor to a Personal Monitor. is linking process is known
as sensor “pairing”, and is initiated through the “Pair” command.
1. Initiate sensor pairing in soware.
When using EMGworks, initiate pairing by right-clicking the Trigno
hardware icon in the system notication area, and selecting the ap-
propriate menu item.
Selecting the Pair command form the Windows Tray Icon.Figure 10.
Right click to access menu options.

TrignoTM Personal Monitor User’s Guide

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 ashes on the sensor, and a conrmational message in the
soware.
Trigno systems are shipped with all sensors appropriately paired. Sen-
sor pairing is typically needed if sensors are being replaced within the
network group, when the communication frequency sets are changed,
and aer a rmware upgrade is performed.
Pushing the sensor button to complete the pairing process..Figure 11.
e system stores calibration information for sensors which have been
paired with it. When collecting data with EMGworks, this calibration
information is used to accurately display measured values, in many
cases without the need for a user-initiated manual calibration. Aer
a pairing operation is completed, the system automatically searches
for pre-existing factory calibration data on the particular sensor. If the
sensor has never been paired with the system (for example, in the case
of a new additional sensor), the soware will prompt the user to enter
factory calibration data, which can be obtained from Delsys. Factory
calibration data are a string a numbers and letters which encode the
calibration values for a specic sensor. Factory calibrations are specic
to a single sensor and will not be accepted by the soware for use on
another sensor. At any time a nominal, “default” calibration may be
selected for a sensor,
or the specic factory
calibration may be re-
entered. is feature is
accessed by re-pairing
the sensor.

autodetected,or entered manually if the sensor is being paired for the rst
time.

Smart Sensors
Aer pairing, the association of sensors to the TPM is retained for all
future uses. Any conguration in EMGworks can be made to reect
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 soware will verify that the sensors currently commu-
nicating match those used in the conguration. If there is a mismatch,
cancel the recording and repair the sensors.
Sensor Modes
Each Trigno sensor can operate in one of 4 possible data collection
modes, which determines the type of data being collected. When
using EMGworks, the sensor mode can be set on the sensor settings
pane for each sensor. Note that the number of modes available is de-
termined by the Trigno sensor type.

Maintenace and Care
Trigno sensor are encased in a sealed polycarbonate enclosure. e
following points should be kept in mind when handling the sensors.
All sensors should be visually inspected before each use to ensure•
that no mechanical deterioration has occurred.
e sensors can be cleaned and sterilized with a damp cloth and•
mild detergent, or with 70% isopropyl alcohol swabs. Ensure that the
sensor contacts remain clean at all times for proper operation.
While the sensors are sealed and are water-resistant, these should•
never be completely submerged in any liquid. ey are design to be
used on damp skin surfaces and in the presence of sweat without com-
promise to safety, sensor integrity or operation.
e sensor contacts are made of pure silver and are quite so.•
Care should be taken to preserve the integrity of these contacts. Do
not scrape or dent these contacts.
Handle the sensors with care: do not drop them on the groun or•
step on them.
Smart Sensors
Do not submerge the sensors in any liquid under any circum-
stance.
e sensors contain sensitive electronic circuitry. Static discharges
and intense magnetic elds should be avoided to prevent the risk of
irreparable damage to the sensors.
