Lovato DMG300 - MODULAR LCD MULTIMETER - EXPANDABLE - GRAPHIC 128X80 PIXEL LCD - HARMONIC ANALYSIS - AUXILIARY SUPPLY 100-240VAC/110-250VDC - MULTILANGUAGE - ITALIAN - ENGLISH - FRENCH - SPANISH AND PORTUGUESE

General characteristics

DMG 300 digital multimeters are available with a modular housing, 4 module size, and are equipped with a graphic backlight LCD capable of providing extremely clear, intuitive and flexible viewing of all electrical parameters of a system.
The very accurate measurements combined with their extreme compactness provide an ideal solution for every type of application.
Expandable with up to 3 EXM series modules interfaced by infrared beam.

Main measurements:
– Voltage: phase, line and system values
– Current: phase values (neutral current calculated)
– Power: apparent, active and reactive phase and total values
– P.F.: Power Factor per phase and total
– Frequency of measured voltage value
– HIGH-LOW-AVERAGE value functions for all measuements
– Maximum demand of power and current values
– Voltage and current asymmetry
– Total harmonic distortion (THD) of voltage and current values
– Harmonic analysis of voltage and current up to 31° order
– Energy meters for active, reactive, apparent partial and total values, programmable tariff functions
– Hour counter for programmable total and partial hours
– Pulse counter for general use: consumption pulse counting for water, gas, etc. with expansion module only.
