Sphygmomanometer Definition. A sphygmomanometer is a device that measures blood pressure. It is composes of an inflatable rubber cuff, which is wrapped around the arm. A measuring device indicates the cuff's pressure. A bulb inflates the cuff and a valve releases pressure. A stethoscope is used to listen to arterial blood flow sounds.
A true root mean square (RMS) multimeter is a measurement device that measures the effective level of alternating current (AC) or voltage.Root mean square is a mathematical term that suggests effective level. Other multimeters may be designed to measure just the average level.he true RMS level is defined as 0.707 of the peak level for a pure sine wave. When the waveform is not a pure sine wave, the relationship between peak and RMS will not be a scale of 1:0.707. Ad. There is a simple relationship between the VDC and the volts root mean square (Vrms).
