Abstract
PURPOSE: To secure an automatic measurement for the surge rating with no destruction by giving the common connection to one of the terminal pairs of the measured objects arranged into a square and switching the other side in sequence.
CONSTITUTION: Control signal 10 is applied to terminal pair switching part 2 and then set to the terminal pair of the sample at square arrangement part 1. At the same time, preset current I0, I1... are applied in sequence from current setting part 3 to measure (4) corresponding voltage V0, V1 and so on. The output of measurement part 4 is compared (5) with the refirence voltage. In case the output is more than the reference voltage, the A/D conversion is given to the voltage and the current value at different conversion parts 6 to be memorized temporarily (7). At the same time, operation 8 and then memorization 7 are given to voltage limit exponent and surge rating N for printing 9 in correspoundence with the preceding memorization. When the readings 4 is under the reference value, comparision output 5 is supplied to control part 10. Then signal 10 reads out memorization 7 via operation part 8 to calculate the average value and the reference deviation of α and N for printing 9. The terminal of sample 11 is connected to switching part 14 and 15 with every matrix, and part 15 has one turn by signal 10 to generate the clock pulse and then to actuate part 14.
