Specifications of the EMG electrode pre-amplifiers included a common mode rejection ratio of 103 dB, bandwidth of 9 Hz-31 kHz, and an impedance of 100,000 MegaOhms
, as reported by the manufacturer.
If the Firefinder is running continuously and the resistivity drops below five megaohms
, the check should be done every few hours to ensure resistivity doesn't drop below one megaohm
of resistivity) was obtained by MilliQ and Elix systems (Millipore Inc).
Moreover, Fairchild's controllers offer a disable function to further reduce power consumption during stand-by mode, and their current-type error amplifiers enable these devices to use a higher Rfb (output-voltage-sensing resistor) over 1 megaohm
, resulting in reduced power loss (80 milliwatts, 2 megaohms
The connector's electrical insulation provides a resistance of over 20 megaohms
, while providing a high temperature life of 1,000 hours at 125 degrees C.
