Abstract

The electrical measuring device (4) comprises a connecting unit (10) for connecting a measuring current transformer (6), and a calibration loop (12) for calibration of a measuring unit of the measuring device and connected to the measuring current transformer. The calibration loop is formed as an electrical conductor and comprises the measuring current transformer. The calibration loop is formed as a rigid portion of a measuring device housing (14). The calibration loop is formed as extending or folding portion of the measuring device housing and formed as handle grip. An independent claim is included for a calibration method for calibrating an electrical measuring device.
