Laboratory wattmeter of CV720.
Ampervoltmetr measures by CV-720 current, tension, power, frequency, power factor with high precision a class of accuracy 0,1.
The CV-720 device is used in power engineering specialists, metrology, expert scientific centers to checking of transformers of current, measuring devices, setup of power supply units, definition of characteristics of electric devices, svetodio and other.
The measuring instrument CV 720 has 3 displays that allows to display 3 parameters at the same time.
The CV-720 measuring instrument can work together with portable transformers of current.
Functions:
TRUE RMS - measurement of mean square values.
High noise stability.
The interface to the personal computer - optionally.
Possibility of calibration via the computer.
