1. A method for operating a meter electronics comprising:
providing a Coriolis mass flowmeter comprising a sensor assembly in communication with a meter electronics, wherein the sensor assembly comprises a driver and a pair of pickoffs in communication with at least one flow conduit, and wherein the meter electronics is configured to provide a signal to the driver that induces vibrations in the at least one flow conduit, and receive a signal from the pickoffs during flowmeter operation;
interfacing a diagnostic tool with the meter electronics;
inputting a base prover volume (BPV) into the meter electronics;
inputting a desired number of passes per run into the meter electronics;
receiving, with the meter electronics, pickoff-derived flowmeter data from the Coriolis mass flowmeter;
calculating, with a proving routine of the diagnostic tool, an estimated total prove time (TPT) necessary to pass a predetermined repeatability requirement, wherein calculating the TPT comprises dividing an uncertainty coverage factor by a target meter factor uncertainty and utilizing the flowmeter data;
calculating an estimated minimum number of runs needed to achieve the calculated TPT;
operating the Coriolis mass flowmeter, with the meter electronics, for the minimum number of runs.
