It is intended for checking and calibration of reference standard power and energy meters, for calibration of precision current and voltage sources and for verification of electrical standard measurements and electricity meter test systems. The unit uses analogue – digital converters (ADCs) for its data acquisition, these being controlled and read by a digital signal processor (DSP).

The comparator may be directly connected to an external computer system over its RS 232 C serial interface. The comparator is distinguished by having very wide measuring ranges for all AC values while still being of accuracy class 0.01%:
Voltage: 30 V … 500 V
Current: 50 mA … 160 A.
In addition low currents from 1 mA are measured. Range selection may be made either manually or automatically. The advanced conception of the K 2006 Comparator
is based on our considerable previous experience of reference standard meters and comparators. The instrument is capable of measuring all principle parameters of a mains frequency network, from 15 to 70 Hz, and harmonics up to 3500 Hz. The basic accuracy of the system is 0.01%. The transfer error of the unit can be verified at any time by using an external DC reference voltage.
