FIELD: measuring equipment.
SUBSTANCE: measuring electronic equipment (20) and method for detecting a change in the vibration meter (5) based on two or more base checks of the meter. Measuring electronic equipment (20) comprises an interface (201) configured to receive sensor signals (100) from the measuring node (10) and provide information based on sensor signals (100), and a processing system (202) connected communicatively with the interface (201), the processing system (202) is configured to use the information in order to determine the first base check value of the meter under a first set of process conditions, determine the second base check value of the meter under a second set of process conditions, and determine the base check value of the meter based on the first base check value of the meter and the second base check value of the meter. The second base check value of the meter is therein determined at the site of the process.
EFFECT: increase in the correctness of detecting changes in the vibration meter, increase in the accuracy of determining the base check value of the vibration meter on-line or in the course of the process, minimisation of false alarms.
