Cosman G4 Radiofrequency Generator Service Manual (SPI 

11291

 Rev A) 

8.2.1 Additional Example Screens 

 
The Graphing Thermal RF screen will appear differently depending on the current settings: 

• 

Electrode Setup settings (see Section 7.1) 

• 

Thermal RF Mode: Standard or Stepped (see Section 8.2.2) 

 

 

Temperature Readings

: 

One Temperature reading 
from each electrode in 
bipolar pair.  For instance, 
“E1” indicates a reading 
from Electrode 1. 

 

Electrode Panel (Black area): 

Displays all readings for the 
indicated bipolar electrode pair, 
e.g. “Electrode 1+2”. 

Standard Mode 

One Electrode 

Standard Mode 

One Bipolar Pair 

Bipolar readings

: Voltage, 

Current, Power, and Impedance 
between the two electrodes in 
the bipolar pair 

Stepped Mode 

One Electrode 

Timer

: Cannot be reset 

in Stepped Mode.
