Description
Lumel MA16, MB16, MA17, MA19 and MA12 Moving-coil meters types are designed to measure d.c. voltage or d.c. current and other physical quantities converted into a current or voltage standard signal.
The panel moving-coil meters MA12, MA16, MB16, MA17 and MA19 are designed to measure current of DC voltage. Magnetoelectric meters with built-in rectifier. MA12P, MA17P, MA19P are intended for measuring the effective currents and alternating current with sinusoidal waveform. Measurement of the current and voltage of the non-sinusoidal waveform is subject to a large error proportional to the degree of deformation of the waveform. What follows from the principle of measuring the rectifier device, which reacts to the average value of the straight-run, but it is calibrated like this to indicate the effective value of the sinusoidal waveform. The noninusoidal course is appropriately characterised, The measurement error is calculated. Therefore, the requirements for the influence of the shape of the curve for the medium-responsive instrument (straightened) are not specified in the standard EN60051-2.
