Method for regulation and monitoring of measuring system, involves measuring, comparing and storing ohmic resistance, cupric resistance, and magnetizing current with reference value from previous calibration measurement

摘要

The method involves measuring the terminal voltage (Uk) and the terminal current (Ik). The ohmic resistance (Rcu), as well as cupric resistance, as well as the size of the reference resistance (Rfe) and the magnetizing current (Imu ) in cyclic recurring distances are measured and compared with reference values from a previous calibration measurement and stored. An independent claim is also included for the measuring system, with regulation and monitoring of the same, e.g. a flow measuring system.
