What do temperature test chamber pv and sv mean?

"PV" and "SV" in the temperature test chamber are two common control panel terms used to control and monitor parameters such as temperature and humidity in the temperature test chamber.Among them, "PV" stands for "Process Value", which refers to the current value of process parameters such as temperature or humidity actually measured in the temperature test chamber. It usually appears on the control panel in the form of a digital or analog display, showing the current actual temperature or humidity. "SV" stands for "Set Point", which refers to the value of parameters such as target temperature or humidity set in the temperature test chamber. It usually appears on the control panel in the form of a digital or analog display, showing the currently set target temperature or humidity. By comparing the actual measured "PV" value with the set "SV" value, the temperature test chamber can automatically adjust its internal environment to reach the required target temperature or humidity. This information can be viewed and monitored through the control panel or computer interface of the test chamber to ensure the stability and accuracy of the temperature test chamber during the test process.It should be noted that the specific meaning may vary slightly according to the temperature test chamber of different brands and models, so you should refer to the corresponding user manual or instruction manual in actual operation.
