Automatic calibration of a measuring circuit

A system for calibrating a measuring circuit automatically in a process to be measured, which system comprises:

• a calibrator, which is connected to a starting point of the measuring circuit of the process to be measured, where the calibrator comprises a controller;
• an impulse signal, which is arranged to be fed from the calibrator to the starting point of the measuring circuit as controlled by the controller;
• an end point of the measuring circuit in a control room, where a measurement result given by the measuring circuit can be read;
• and
• transmission means for sending the read measurement result digitally back to the calibrator;
• wherein that the system further comprises:
• storing means, which are arranged to store both the impulse signal and the read measurement result automatically in a desired place, so that the system further comprises a delay module for delaying the storing of the impulse signal, so that the sent read measurement result is stored at the same time as the impulse signal, and connected as a numerical value pair.

A non-transitory computer readable medium having a computer program for calibrating a measuring circuit automatically in a process to be measured, which computer program comprises a program code, which can be run in a processor, which computer program is arranged to perform the following steps when run in the processor:

• feeding a desired impulse from a calibrator into a starting point of the measuring circuit after the calibrator has manually been connected to the starting point of the measuring circuit in the process to be measured;
• reading a measurement result given by the measuring circuit at an end point of the measuring circuit in a control room;
• and
• sending the read measurement result digitally back to the calibrator;
• wherein that the computer program is further arranged to perform the following step:
• storing both the desired impulse and the read measurement result automatically in a desired place, so that the storing of the desired impulse is delayed, so that the sent read measurement result is stored at the same time as the desired impulse, and connected as a numerical value pair.
