Audio Volume; Return Electrode Sensing; Low Frequency (50-60 Hz) Leakage Current - Bovie AARON 2250 Service Manual

Audio Volume

The audio levels stated below are for activation tones (cut, coag, and bipolar) and alarm tones (return electrode and
system alarms) at a distance of one meter. Alarm tones meet the requirements for IEC 60601-2-2.

Return Electrode Sensing

The system presents audible and visible alarms when it senses no return electrode.

Cut: 1 kHz
Blend: 1 kHz
Coagulation: 2 kHz
Fulguration: 2 kHz
Bipolar: 2 kHz

Trip resistance: 0 Ω to 5 Ω ± 3 Ω
Continuous measurement:
Once the system establishes the solid return electrode resistance, an
increase of 20 Ω ± 5 Ω in resistance will cause an alarm. When the
alarm condition exists, the system deactivates output power.
Trip resistance: 10 Ω ± 5 Ω to 135 Ω ± 10 Ω
Continuous measurement:
Once the system establishes the split return electrode resistance, an
increase of 40% in resistance will cause an alarm. When the alarm
condition exists, the system deactivates output power.
