The range of LOVATO Electric metering instruments is continuously being extended with the release of the new
flush mount graphic LCD models.
DMG 700 and DMG 800 digital multimeters are capable of viewing the
measurements with high accuracy on the wide graphic LCD, which allow
to control energy distribution systems. They are available with a
flush-mount housing, 96x96mm size, and 4 expansion slots to fit
plug-in expansion modules suitable for numerous applications. The
main features of these multimeters include an extended power supply
voltage range, high measurement accuracy, expandability and graphic
interactive interface for simple use.
The models are differentiated as follows:
- DMG 700 basic version
- DMG 800 with harmonic analysis version
The
main electric parameters are:
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 function: instantaneous
measurement and storing of minimum and maximum values of
voltage, current, power P.F. and frequency values
Averaging function
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 the 31° order with DMG 800 only
Energy meters for active,
reactive, apparent partial and total values with programmable
tariff functions
Hour counter for programmable
total and partial hours
Pulse hour counter for general
use: pulse counting for water, gas, etc. consumption with
expansion module only.
