The study is used to understand the working procedure of the Olympus PSD-30 Electrosurgical Unit which a high-frequency alternating current is to measure the voltage and power output from the unit when used for a surgical operation to determine the extent of tissue damage. The output power and voltage were as examined with the stopwatch, then with an Arduino time based for 1, 2, and 3 seconds to understand the different modes of the cut and coagulation feedback with an RCC circuit used to mimic the human body. This shows a pattern in which the feedback power increases, and voltage decrease as the cut and coagulation mode increases. The percentage between the stopwatch and Arduino is 29% for the 1 and 2 seconds. With this information, Arduino Uno timing was used to carry out the experiment for the device for the different power settings for both the cut and coagulation mode from 2W to 50W at 5W intervals. Based on each trial, the signal was measured for a magnitude of 1Vpp, and the crest factor obtained was 1.5 with a voltage of 1.088v and 1.0519v for both the LabView and Oscilloscope respectively for the Electrosurgical Unit of 350kHz. The power control gives 0.4W, 2.04W, and 3.01W for the power peak at 1, 2, and 3 seconds for the 50W Cut mode of the Electrosurgical Device.
