MA16, MB16, MA17, MA19 and MA12 moving-coil meters are intended
for measuring d.c. voltage or d.c. current. These meters with built recti-
fiers can also be used for measuring a.c. voltages and a.c. currents.
MA17P, MA19P, MA12P meters with built-in rectifiers are used for
measurement of the rectified current or voltage arithmetical mean
value and they are such calibrated that they indicate the RMS value
at sinusoidal curve shape. The measurement of non-sinusoidal a.c.
magnitudes results in additional errors.
MA16, MA17, MA17P, MA19, MA19P, MA12 and MA12P meters
are designed for mounting into panels. MB16 meters are adapted
for a fast assembly rail mounting (35 mm rail) in compliance with
EN 60715 standard MA16, MA17 and MA19 meters are designed for
interchangeable dials.
TECHNICAL DATA
Accuracy class 1.5
Internal resistance,
voltage drop, current
or power consumption acc. tables 1, 2 and 3
Adaptation of the meter
measuring range to the
range of interchangeable
shunts or measuring
transducers by changing of the dial: the dial is
simply extracted with a suitable tool
and replaced through the upper
slot of the case
Note: MA12 (144 x 144) meters
are not provided for interchangeable
dials
CATEGORIES OF METER CLIMATIC VERSIONS
If it is not written otherwise in the order, these meters are intended
to use in moderate climatic conditions. Then, we do not place any
symbol on the scale. On customers’ request, meters can be adap-
ted to use in conditions of a dry or wet tropical climat.
Then, they are marked with the T III symbol.
