Peritonitis is inflammation of the peritoneum â a silk-like membrane that lines your inner abdominal wall and covers the organs within your abdomen â that is usually due to a bacterial or fungal infection.
A true-rms device (rms = root mean square) is one of three tools that can measure alternating current (ac) or ac voltage: 1  True-rms digital multimeters (or clamp meter).2  Average-responding digital multimeter (or clamp meter). more sophisticated true-rms meter can accurately measure both pure waves and the more complex nonsinusoidal waves. Waveforms can be distorted by nonlinear loads such as variable speed drives or computers. An averaging meter attempting to measure distorted waves can be up to 40% low or 10% high in its calculations.
In a direct current (DC) circuit, voltage or current is simple to define, but in an alternating current (AC) circuit, the definition is more complicated, and can be done in several ways. Root-mean-square (rms) refersto the most common mathematical method of defining the effective voltage or current of an AC wave. To determine rms value, three mathematical operations are carried out onthe function representing the AC waveform: (1) The square of the waveform function (usually a sine wave) is determined.
