Symptoms

Calibration: Cut 3 output power (PULSAR II) high voltage

Verification that CUT mode 3 on PULSAR II outputs 6 Watts at 100Ω impedance within ±20% tolerance per IEC 60601-2-2

Ranked causes

1. Routine calibration check per IEC 60601-2-2 standard (common)

First check

Set ESU load to 100 Ohms

Test point: ESU load control
Expected: 100 Ω selected

Verify RF output power accuracy high voltage

Measurement of radio frequency energy output across CUT and COAG modes at various power levels to confirm generator compliance with IEC 60601-2-2 standard

Ranked causes

1. Routine preventive maintenance calibration required (common)

First check

Connect PEAK PlasmaBlade device to generator under test

Test point: Generator RF output connector
Expected: Device connected and recognized
