Accuchek-HT+ is a portable device for error testing of high voltage energy meters installed in the field.  Operation is menu-driven for ease of use and the enclosure is rugged, ensuring years of reliable service in the field.  It supports both static and electro-mechanical meter types.  



  • Service testing of energy meters

    Electricity meters are the main source of revenue for energy suppliers. Without accurate metering data the supplier will lose revenue. Suppliers are responsible for ensuring that metering is installed and maintained correctly, so that consumers are billed correctly. Meters are sometimes installed incorrectly, with wires swapped over, or with incorrectly configured instrument transformers. The inherent complexity of three-phase installations makes such errors difficult to detect and rectify.

    For these reasons it is essential to perform periodic in-service testing of meters and associated equipment.
