METHOD FOR A ONE-TIME CALIBRATION OF A MULTIPLE BRANCHES DIGITAL MEASUREMENT SYSTEM WORKING IN MINIMUM NUMBER OF BRANCHES MODE

摘要

The method of the one-time calibration of a digital measurement system according to the invention is performed so, that the first evaluated voltage (U<SUB>1</SUB>) is supplied identically on the first input (I<SUB>11</SUB>), (I<SUB>21</SUB>), to the first input (I<SUB>X1</SUB>) of the first branch (V<SUB>1</SUB>), second branch (V<SUB>2</SUB>) to the last possible branch (V<SUB>x</SUB>). In the first step each branch stores, in parallel, the sequence of partial immediate information from each branch's respective first output (O<SUB>11</SUB>), (O<SUB>21</SUB>) to (O<SUB>x1</SUB>) through the input bus (BUS<SUB>IN</SUB>) to the determined partial raster (DPR), divided into the entered number pursuant to nth order number (n<SUB>n</SUB>) of the parallel structured areas, starting with the first structured area (OB<SUB>1</SUB>), second structured area (OB<SUB>2</SUB>) to the last possible structured area (OB<SUB>n</SUB>), i.e. the first possible partial information (OU<SUB>11</SUB>), the second possible partial information (OU<SUB>21</SUB>) to the last possible partial information (OU<SUB>x1</SUB>), together with the first order number (n<SUB>1</SUB>) of the first structured area (OB<SUB>1</SUB>), with the second order number (n<SUB>2</SUB>) of the second structured area (OB<SUB>2</SUB>) to the nth order number (n<SUB>n</SUB>) of the last possible structured area (OB<SUB>n</SUB>) of the determined partial raster (DPR). In the second step the comparator (K), on the basis of a comparison of the respective pairs of partial immediate information of the individual branches, evaluates the result of the comparison so that when the immediate values of two units of partial information of two branches from the set of the first possible branch (V<SUB>1</SUB>), second possible branch (V<SUB>2</SUB>) to the last possible branch (V<SUB>x</SUB>) are in the same identical area, i.e. in either the same first area (OB1), in the same second area (OB<SUB>2</SUB>) up to in the same nth area (OB<SUB>n</SUB>), or if their first order number (n<SUB>1</SUB>), second order number (n<SUB>2</SUB>) to nth order number (n<SUB>n</SUB>), differ at most by a value of one, then the digital measuring system (DMS) declares, through the output (KV1) of the comparator (K), the correctness of the evaluated voltage (U<SUB>l</SUB>) by its first logical correct output unit (COU<SUB>1</SUB>).
