ELECTRICAL MULTIMETER
The digital multimeter EMM-4 allows to monitor all the electrical parameters present on a distribution line. The local display of 30 electrical
parameters is carried out by 4 displays with red LED. In this way, you are granted a good reading of many parameters at the same time. A
simple front panel completes the intuitive selection of several electrical parameters, supplying a great deal of information. On top of measuring
all parameters instantaneously, these instruments display the maximum value of currents, active power and thermal currents. The EMM-4
multimeter replaces in an unique device all the functions of: Voltmeters, ammeters, cosphimeters, wattmeters, varmeters, frequency-meters
and thermometers allowing a great energy saving, and overall dimensions and wiring decrease. An easier purchase and a better management
in instruments is achieved considering that the same model satisfies all the options of the local measure in electrical board instruments.
EMM-4 is flush mounted in panel DIN 96x96 with extreme depth.

Read carefully the instructions in this manual before installing the digital multimeter.
The instrument described in this manual is intended for being used only by properly trained staff.
This instrument has been manufactured and tested according to IEC 1010 standards. In order to maintain these conditions and to ensure safe
operation, the users must follow the instructions of this manual.
Before the installation, check that it's still intact and no damage has been suffered during transport and make sure that the operating voltage
and main voltage are compatible with the device instructions.
The instrument power supply must not be earthen. Maintenance and/or repair must be carried out only by qualified and authorised staff.
Should it be considered that there is a safety loss during operation, the instrument must be disconnected and precautions taken against
accidental use.
4 WIRES SYSTEM: On 3 wires insertion (with or without neutral not distributed) don't connect the terminal N.
