Performance Characteristics
If the measured resistance is outside the acceptable range(s) noted above, a REM fault
condition occurs.
REM Alarm Activation
REM Polyhesive Patient Return Electrode: When the measured resistance exceeds the
standard range of safe resistance (below 5 Ω or above 135 Ω) or when the initial
measured contact resistance increases by 40% (whichever is less), the REM Alarm
indicator flashes red, a tone sounds twice, and RF output is disabled. The indicator
remains illuminated red until you correct the condition causing the alarm. Then, the
indicator illuminates green and RF output is enabled.
Patient return electrode without the REM safety feature: When the measured
resistance between the patient return electrode pins exceeds 20 Ω, the REM Alarm
indicator flashes red, a tone sounds twice, and RF output is disabled. The indicator
remains illuminated red until you correct the condition causing the alarm. Then, the red
indicator is extinguished and RF output is enabled.
Serial Port

RF Activation Port
The RF activation port is a subminiature telephone jack attached to the contacts of a
small relay. The contacts are closed when the output is energized and open at all other
times. This port provides a means to tell other equipment that RF current is being
generated. This may be useful when making EEG or ECG measurements.
