ELECTRICAL MULTIFUNCTION METER
GENERALITY
These digital multimeters allow to monitor all the electrical parameters
present on a distribution line. The local display of 30 electrical parameters
is carried out by 4 display with red LED guaranteeing a good and
contemporary reading of more measures. A simple front panel completes
the intuitive selection of several electrical parameters, with a great quantity
of information. These instruments, over of the instantaneous measures,
display the maximum peak of the main parameters (maximum peak and
maximum demand). The presence of the serial port communication
EIA485 (option) allows the connection in network of more instruments to
realize centralized measure networks.
These multimeters replace in a unique device, all the functions of
voltmeters, ammeters,
varmeters, frequency meters permitting a great economic saving, a reduction of dimension and the wiring energy and
a simplification in the purchase and management of the instruments because this is a model usable at all of need of
local measure in the electrical panel, machine, etc.
