Acceptable Resistance Range
REM resistance measurements are ± 10% during RF activation and ± 5% when RF output
is not activated.
REM Polyhesive patient return electrode: 5 to 135 ohms or up to a 40% increase in the
initial measured contact resistance (whichever is less)
Patient return electrode without the REM safety feature (single section electrode): 0 to 20
ohms
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 ohms or above 135 ohms) 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 ohms, 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
RS-232 compatible; 9600 baud, 8 data bits, 1 stop bit, no parity
The 9-pin connector supports the following signals:
• Pin 2 – isolated transmit (serial data output transmit line)
• Pin 3 – isolated receive (serial data input receive line)
• Pin 5 – isolated ground (reference for transmit and receive)
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.
