A failure of the heater circuit 42 can be detected. For example, if the PT sensor 63 measures a higher temperature than the coolant while the power to the heater 62 is turned off, it can be detected that the power supply 50 is not turned off. In this case, the heater circuit 42 can take measures to cut off the power supply from the power supply 50.
- the thermal contact resistance between the temperature control block 61 and the DUT 32 can be obtained.
- the thermal contact resistance is large, the temperature change per unit time detected by the PT sensor 63 is small.
- test control unit 10 performs control to turn off the device power supply 21. As a result, it is possible to prevent heat generation and burning due to poor contact of a connector or the like during a burn-in test in which a large current flows through the DUT.
