Minimum power control setting test
a. For units with stepped or continuously variable power level controls verify at the minimum power setting there is zero output power at the zero control setting. If the unit has no zero setting, verify the minimum output power at any load resistance in the range of 100 to 1000 ohms does not exceed 5 percent of the maximum output power for that mode.
b. For units with momentary activation switches, verify the unit is set to zero power level or “standby” mode at initial power-up.
Line voltage fluctuation test. Verify that the output power measured at the active electrode remains constant within 10 percent when the line voltage is fluctuated over the tolerance range specified for each voltage/frequency combination specified under salient characteristics paragraph 19.
Visual Indicators test. Verify the unit provides separate visual indicators for input power turned on and for output activated.
Audible indicators test. Verify the unit provides distinct audible tones to indicate cut and coag/bipolar activation. Verify the volume cannot be reduced below 45 dB.
Output isolation test. Verify the power delivered to a 200 ohm load connected between each active output and ground does not exceed 4.5 watts at maximum output power setting.
Radio frequency leakage test. Verify the power delivered to a 200 ohm non-reactive resistance connected from the dispersive electrode to ground does not exceed 4.5 W at maximum output power setting with the electrodes operated open-circuited.
Electrical safety test. Verify no more than 500 uA of sink current flows to ground with 110 v. 60 Hz applied to the active or return electrode.
Metric products. Products manufactured to metric dimensions will be considered on an equal basis with those manufactured using inch-pound units, providing they fall within the tolerance specified using conversion tables contained in the latest revision of Federal Standard No. 376, and all other requirements of this document are met.
