Checking of electric energy meters

Control meter LK-10

DESCRIPTION

Control meter accuracy is defined at level 0.1%. Direct and indirect (Dietz clamps) currents inputs extend meter’s usability. It is possible
to connect meter head (e.g. GL-10) and hand probe (e.g. GR-10) for checking slow-running meters. The possibility of test report direct printing on thermal printer, connected to control meter is a very useful facility. LK-10 meter enables determining the error of meter’s counter, direction of phase rotation and measurements (True RMS) of voltages, currents, power and energy. Control meter is small and lightweight, its safety and tightness enclosure provides good protection in rough operating conditions.
This device is assigned for Power Utility services, it is specially useful in fighting against illegal power consumption, combined with neodymium magnets applying.
Very high accuracy class and low, competitive price are additional
features of the meter.

PURPOSE

Control meter LK-10 enables uncertainty determination of induction and electronic energy (active and reactive) meters, as well as measurement of basic parameters of one- and three phase networks.
