MA17 - MOVING-COIL METERS
APPLICATION
The panel meters type MA12. MA16. MB16. MA17. MA19 are designed
to measure current or DC voltage. Magnetoelectric meters with built-in
rectifier type 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. Where the noninusoidal course is appropriately characterized. this 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 EN 60051-2.
MA12 meters. MA16. MA17. MA19 are suitable for mounting in a panel
of thickness not exceeding 25 mm in the holes according to Figures
3 and 4. The meter MB16 is suitable for snap fastening on the 35 mm
rail bracket according to EN 60715.
