3.3 Functions
The power analyzer allows for the analysis of currents from DC to
several MHz. Voltage values up to 1000 V and currents up to 20 A
are measured accurately, and the respective real, idle and
apparent power is calculated. The limit of error is between 0.1%
and 0.3%, depending on the model. For DC and AC up to a few
MHz, it is not affected by the wave shape, frequency or phase
position. The measuring range can be extended by connecting
shunts or clamps. When extending the range using third-party
shunts or clamp the extra errors due to these devices should be
considered. The device caters for simultaneous measuring in up to
6 channels.
