| Zusammenfassung: | A balance for measuring masses and forces comprising a phase-locked frequency multiplier which multiplies the string frequency F1 that is raised by the process of measurement with a predetermined fixed factor in such manner that the multiplied frequency retains a constant phase relationship with the original frequency and wherein the number of full cycles of the multiplied frequency F1 is counted for a period of time corresponding to a given number of full cycles of the frequency F2, which frequency is reduced by the measuring process. |
