<p>PROBLEM TO BE SOLVED: To reliably and easily select only nonlinear resistors, each having an energy absorbing power above a certain level. SOLUTION: This cleaning method comprises step 1 of flowing a current having specified energy in a nonlinear resistor having electrodes, step 2 of measuring the temp. distribution over the electrode forming face when the resistor absorbs specified energy during the current flowing step 1, step 3 of computing the distribution of a caused thermal stress, based on the measured temp. distribution, and step 4 of judging if the max. value of the thermal stress on the outside of the resistor meets specified conditions determined as a selection criterion.</p> |
