DMECDPV1 is specific for the monitoring of solar
installations and needs to be connected to at least two
DMED… meters (single or three phase). The user can avail
of data, such as energy produced by the generating
installation, energy consumed by loads as well as exchanged
energy (difference between import and export energy) with
the power supplier.
It is already programmed to automatically calculate the selfconsuming index, mean power values, production (total and
partial values) and the operating status of the AC/DC inverter,
if it is equipped with digital outputs.
In addition, it can be customised by the user for load
supervision, using the EXM series expansion modules,
according to the defined logics and on the basis of the
energy available.

General characteristics
DMK3... and DMK40 digital multimeters are available with
flush-mount housing, 96x96mm/3.78x3.78” size. They
comprise excellent features so distorted waveform
conditions, such as very disturbed supply lines having
voltage and currents with high harmonic content and variable
freqeuncy, do not influence the high accuracy of DMK
multimeter readouts, because of the rigorous deisgn in
addition to the use of the latest generation of microprocessor
technology. Measurement of the phase angle (cos) in
addition to power factor, harmonic analysis and HIGH-LOWMAX DEMAND functions are just a few of those which are
difficult to find on higher category equipment.
The DMK 40 version includes a reliable data-logger system,
extremely easy to use. DMK 3... and DMK 40 multimeters can
display 251 electric parameters; a few of these are listed below:
– Voltage: phase, line and system values
– Current: phase and system values
– Power: active, reactive, apparent phase and total values
– Energy: import, export, active and reactive values
– P.F.: power factor per phase
– cos: angle displacement, i.e. power factor related to
the harmonic fundamental only
– Frequency of measured voltage value
– Harmonics (HARM.): residual and total harmonic
content for each harmonic order up to the 22° per
phase, both for voltage and current values
– HIGH / LOW: maximum / minimum values of phase
voltage and current and W, var and VA power
– Maximum demand (MAX): maximum current and total
active power values, both calculated on programmable
integration time.
The technical features of the DMK 40 data-logger are:
– 2Mbyte (MB) non-volatile memory for data logging
– Real Time Clock (RTC) with replaceable backup lithium
battery
– Sampling time, 1s to 24h configurable
– Number of sampling measurements, 1 to 32
configurable at a time

General characteristics
DMK6... digital multimeters are avaibalble with modular
housing, 6 module size. They comprise excellent
features, superior to devices of the same category
currently on the marketplace. Distorted waveform
conditions, such as very disturbed electric lines having
voltage and currents with high harmonic content and
variable frequency, do not influence the high accuracy
DMK multimeter readouts because of rigorous design in
addition to the use of the latest generation of
microprocessor technology. Measurement of the phase
angle (cos) in addition to power factor, harmonics
analysis and HIGH-LOW-MAX functions are just a few of
those which are difficult to find on higher category
equipment.
DMK 6... digital multimeter can display 251 electric
parameters; a few of these are listed below.
– Voltage: phase, line and system values
– Current: phase and system values
– Power: active, reactive, apparent phase and total values
– Energy: active, reactive import and export values
– P.F.: power factor per phase
– cos: angle displacement, i.e. power factor related to
the harmonic fundamental only
– Frequency of measured voltage value
– Harmonics (HARM.): residual and total harmonic
content for each harmonic order up to the 22° per
phase, both for voltage and current values
– HIGH / LOW: maximum / minimum values of phase
voltage and current and W, var and VA power
– Maximum (MAX): maximum current and total active
power values, both calculated on programmable
integration time.
Operational characteristics
– Auxiliary supply voltage range:
85-265VAC/93.5-300VDC
– Voltage measurement range: 20-830VAC phase-phase
10-480VAC phase-neutral
– VT ratio programming: 1.0-5,000
– Current measurement range: 0.02-6A
– Frequency measurement range: 45-65Hz
– CT ratio programming: 1.0-2000
– Accuracy: Voltage ±0.25% f.s. (830V)
Current ±0.35% f.s. (6A)

– Active energy accuracy: Class 1
– HIGH and LOW value functions to detect and log
instantaneous voltage, current and power values
– Averaging function to slow down repetitive
fluctuations to obtain more stable readouts
– Current connection in ARON configuration via 2
current transformers only
– Single, two, three phase with or without neutral and
balanced three-phase connection via 1 current
transformer only

General characteristics
The DM... series current transformers (CTs) are installed
in electric installations to reduce the line current to a
secondary value of 5A, which is compatible with current
inputs of digital multimeters or protection relays.
These are without primary winding and are used for high
primary current values from 50A upward.
The number of loops of the primary cable does not
modify the accuracy but converts the primary current
value proportional to secondary current.
Consult Customer Service to query about versions with Italian UTF
certificates; see contact details on inside front cover.
