Problem Possible Cause
output shuts down prematurely
• Temperature above 100 °C.
• Break in electrode or electrode cables.
May be intermittent problem.
• Set Time setting too low
• Maximum RF Current or Power limit
exceeded
• Electrodes attached to generator do not
match Electrode Setup
Temperature does not reach Set Temp or
Max Temp setting
• Required total RF Current or Power limit
exceeds allowed limit
• Total Impedance too low
• Too many electrodes energized
simultaneously
• Set Temp or Max Temp too high
• Temperature can only be controlled on
one electrode in a Bipolar Pair
• Ground pad used when RF Type=Bipolar
