Abstract
A jaw heating element of a handpiece of a thermal tissue operating system is tested on an ongoing basis by supplying a test heater power signal to the jaw heating element between individual thermal tissue operations. Voltage and current through the jaw heating element is sensed and the resistance of the jaw heating element is calculated. If the calculated resistance is outside a range of predetermined acceptable values, an error condition is indicated.
