Ordinary DC voltmeter can only measure DC voltage signals, while the measurement of AC signals must increase the AC/DC conversion circuit. Currently commonly used AC voltmeter to reduce costs and simplify the circuit, are using a simple average response AC/DC converter. Commonly used average response AC/DC converter is an operational amplifier and diode composed of half-wave (or full-wave) linear rectifier circuit, this circuit has good linearity, high accuracy, simple circuit, low cost and other advantages. However, this circuit is in accordance with the standard sine wave average value and the effective value of the relationship (VRMS = 1.111Vp) to define, so this type of instrument can only measure the standard distortion-free sine wave voltage value. For sinusoidal distortion of AC voltage signals, this type of instrumentation will be measured in error, and the use of such instruments to measure square waves, rectangular waves, triangular waves, sawtooth waves, trapezoidal waves, step waves, and other non-sinusoidal signals of the deviation is even greater, the detection results and the actual value of the signal does not match. The use of true RMS digital instruments can accurately measure the RMS value of various waveforms to meet the needs of modern electronic measurement.

Product Description

Ordinary DC voltmeters can only measure DC voltage signals, while AC signals must be measured by adding an AC/DC conversion circuit. Currently commonly used AC voltmeters use simple mean-response AC/DC converters in order to reduce cost and simplify circuitry. The commonly used mean-response AC/DC converter is a half-wave (or full-wave) linear rectifier circuit composed of an operational amplifier and a diode, which has the advantages of good linearity, high accuracy, simple circuitry, and low cost.However, this circuit is defined in terms of the standard sine wave mean value versus rms value (VRMS = 1.111Vp), so this type of meter can only measure standard undistorted sine wave voltage values. For sinusoidal distortion of AC voltage signals, this type of instrumentation measurement will be an error, and the use of this type of instrumentation to measure square, rectangular, triangular, sawtooth, trapezoidal, step wave and other non-sinusoidal signals deviation is even greater, the detection results do not match the actual value of the signal. The use of true RMS digital instruments can accurately measure the RMS value of various waveforms to meet the needs of modern electronic measurements.

The heart of the True RMS meter is the TRMS signal isolation amplifier module. The TRMS module is composed of a monolithic TRMS/DC converter as the core and adopts the new D-S calculation technology, configured with a high-precision signal isolation amplifier. Its advantage is that it can accurately and real-time measure the RMS value of various voltage and current waveforms without considering the waveform parameters and the size of the distortion. In short, the True RMS Measurement Module TRMS is characterized by high accuracy (30Hz-1kHz error <0.25%), good linearity (non-linear error <0.02%), a very wide dynamic current range, fast response time, wide measurement surface, and ease of use. Shenzhen SunYuan Technology Co., Ltd. research and development and production of the new true RMS isolation amplifier module TRMS series products have a high degree of integration, perfect functionality, less peripheral components, simple circuit connections, electrical performance indicators are easy to ensure that many of the advantages of the use of this module can be accurate, real-time measurement of the RMS value of a variety of signal waveforms without regard to the parameters of the waveform and the distortion of the performance of the average value of the measurement instrumentation can not be achieved.
