ABSTRACT:
A meter provides an arrangement for the optional connection of its voltage circuit to a current path or to a calibration system. The arrangement includes an opening, provided in the housing of the meter for inserting a contact device connected to the calibration system, and a pivoting lever. On insertion of the contact device into the opening, the pivoting lever can be moved from an operating position, connecting the voltage circuit to the current path, into a calibration position connecting the voltage circuit to the calibration system. Consequently, the arrangement can be changed over between the operating position and the calibration position with a minimum possible cost.
