7. Resume from Step 6 to test the other power output presets.
Note Note: Nominal impedance is 200 ohms. However, due to output
modulation, the electrosurgical analyzer power signal is unstable
at 200 ohms. Therefore, this test is conducted at 250 ohms, where
modulation does not occur.
If this test reveals that power output levels that are outside of the suggested values,
please return the SERFAS Energy generator for service, as described in Services
and Claims.
