GENERAL INFORMATION
The EMM digital multimeters allow the measurement of the
main electric quantities in the distribution networks. The local
display of more than 30 measurable quantities is performed
by means of four red LED displays, thus providing an easy
legibility and the simultaneous display of several measures. A
simple front panel easier the intuitive selection of several
electric quantities, supplying a great number of information.
These instruments, besides the instantaneous measures,
display the maximum peak of the main parameters
(maximum peak and maximum demand or maximum average
value).
The EMM multimeters group in a single instrument the
functions of voltmeters, ammeters, power factor meters,
wattmeters, varmeters, frequency meters, thermometers,
allowing remarkable financial savings, a reduction of the
dimensions and of the time required for the wiring; also the
purchase and the management of this instrument is easier,
as all the above functions can be performed by one product
only, which can be used for all local measurement
requirements in switchboards, machines etc.
