Connecting to a Voltage Monitoring Device
Connect the 0-2V output jack (see figure 8) to any instrument
capable of reading from 0-2 Volts (digital voltmeter, analog
voltmeter, polygraph, integrator, etc.). Make certain the instrument
is battery operated or complies with IEC 601-1. The output voltage
will always be in the 0-2 Volt range; however, the actual EMG level
in microvolt RMS is dependent upon the Gain setting. Range values
are obtained by multiplying the output voltage reading as follows:
Switch = x1, multiply by 10
Ex: Voltage = 0.9; EMG = 9
V
Switch = x10, multiply by 100
Ex: Voltage = 1.5; EMG = 150
V
Switch = x100, multiply by 1000
Ex: Voltage = 1.1; EMG = 1100
V
Care of Your Instrument
Basically, no maintenance, other than cleaning, is required.
Any surfaces which come in contact with skin should be cleaned
after each use by wiping with a damp cloth. If conductive gel is
used, be careful not to apply any gel on the sensor head. If gel gets
inside the sensor’s electrode connectors, clean immediately with a
moistened cotton swab to remove the gel.
IMPORTANT POINTS TO REMEMBER:
Protect from static electricity
:
The MyoTrac and MyoScan
are sensitive electronic instruments, and should be handled as such.
Damage can occur if used in dry, carpeted areas without a static mat
or a static guard product sprayed on the carpets.
