Audio Volume; Return Electrode Sensing; Low Frequency (50-60 Hz) Leakage Current - Bovie Aaron 1250 User Manual

Audio Volume

The audio levels stated below are for activation tones (bipolar, cut and coag) 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.
Single Plate
Split Plate

Low Frequency (50-60 Hz) Leakage Current

Enclosure source current, ground open
Source current, patient leads, all outputs
Sink current at high line, all inputs

40 to > 65 dB
Cut: 610 Hz ± 10 Hz
Blend: 610 Hz ± 10 Hz
Pinpoint: 840 Hz ± 10 Hz
Spray: 840 Hz ± 10 Hz
Bipolar: 840 Hz ± 10 Hz

> 65 dB at a distance of one meter
2.44 kHz / 450 ms / 1.22 kHz / 450 ms
Trip resistance: 0 Ω to 8 Ω ± 1 Ω
Continuous measurement:
Once the system establishes the single-plate electrode resistance, an
increase of 20 Ω ± 25 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-plate electrode resistance, an
increase of (35 ± 5)% in resistance will cause an alarm. When the alarm
condition exists, the system deactivates output power.
