Measuring System

The Power Analyzer NORMA 4000 measures exactly current and voltage and calculates active, reactive and apparent power and other derived values.

The accuracy of this instrument does not depend on the wave form, frequency and phase shift in a wide range.

Harmonics are calculated up to half the sampling rate.

The DSO – function visualises the values in wave form.

Voltage and current can be measured directly due to integrated voltage dividers and shunts. It is also possible to connect external voltage dividers as well as shunts or probes.

Options like additional interfaces, analogue inputs and outputs are available.

The firmware of the analyser can be updated via the standard interface RS232.

High Precision

The Power Analyser NORMA 4000 is designed to measure signals in a wide frequency range from DC to a few MHz. The input stages are DC coupled, suited with high quality pulse amplifier.

A zero- and offset calibration against a stable voltage reference runs automatically in short time periods to stabilize the accuracy.

All voltage and current channels are separated by a completely new technology of barriers for high channel isolation and common mode rejection. That makes the analyser NORMA 4000 also suitable for difficult applications.
