PCT No. PCT/DE88/00210 Sec. 371 Date Dec. 1, 1989 Sec. 102(e) Date Dec. 1, 1989 PCT Filed Mar. 31, 1988 PCT Pub. No. WO88/07658 PCT Pub. Date Oct. 6, 1988.A process and arrangement for evaluating a measurable analog electronic quantity based on the principle of the timekeeping mechanism, in which the measurable analog quantity is digitalized by counting integration processes. To exploit the simplicity and precision of the timekeeping mechanism principle also far fast and precise digital data conversion units, a deviation coding phase (AV) is inserted between the timekeeping mechanism periods (T), in which post-adjustment of the timekeeping mechanism timing ratio is possible with rapid digital circuits even in the event of abrupt fluctuations of the quantity to be measured. The invention is generally applicable for highly precise and rapid digital data conversion of analog quantities, and is especially advantageous in high-precision measuring instruments with measuring sensors in bridge circuits, for example in weighing cells based on the DMS principle in electronic balances. |
