GENERALITY
These digital multimeters series 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, energy meters, cosphimeters, wattmeters, 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.

OPTIONS

- internal CT
- digital output (in alternative to the serial port)
- serial port (in alternative to the digital output)
- power supply different from standard version
- current input 1A
