Claims

[Scope of utility model registration request]

In an intermittent energization test device that performs a test by controlling the energization on and off of the product under test at a constant cycle, during the energization period for the product under test, a first timer is used to measure the preset energization on time. , and a first temperature regulator that measures the upper limit set temperature of the product under test, and the energization is turned off while giving priority to the temperature condition set by the first temperature regulator. During the period when the energization is turned on again later, a second timer that measures the preset energization off time and a second temperature regulator that measures the lower limit set temperature of the product under test are used together, and after the energization off time has elapsed, The intermittent energization is characterized in that the energization off period ends when both conditions are satisfied, and the lower limit temperature set by the second temperature regulator is satisfied, and energization is started again to the test object. Test equipment.
