WebOn start up, all zone set points find and start at the current temperature, usually room temperature, then ramp up to the target temperature at the rate selected. Because the … WebIn RTA processes, using spike RTA with fast ramp-up and ramp-down rates has become an important means of achieving USJs. The temperature ramp rate depends on the wavelength and intensity of the infrared radiation source, the characteristic response time of the system for switching from heating to cooling, and the heat dissipation mechanism ...
