How to view the temperature recovery time of the high and low temperature two-box impact test chamber

After the application time of the machine and equipment, there is always a trace of unpleasantness, sometimes the temperature repair time is not timely will also endanger people's inspection results, the manufacturer will choose the following process to detect the temperature repair time of the hot and cold impact environment test box: (1) install a temperature detection controller in accordance with the specified part, and adjust the temperature controller of the high temperature box and the low temperature box to the specified tolerance temperature
.

(2) Raise the shell and reduce the heat respectively, and record the temperature value
measured at the control point after the heat and cold impact environment test chamber enters the temperature control situation for 30 min or the time when it is stable and relative according to the technical standards of the product.

(3) Embed the detection load into the high-temperature machinery and equipment, and select the relative maintenance time according to the requirements of the technical standards of the goods or the requirements of the relevant specifications
.

(4) Select the hot and cold impact environment test box, the two-compartment hot and cold impact environment test box, the two-box hot and cold impact environment test box to change the time, and then transfer the detection load from the high temperature machine equipment to the ultra-low temperature machine equipment, pay attention to the observation and record the temperature measured at the control point; In the same way, the detection load is changed from ultra-low temperature machines and equipment to high temperature machines and equipment, and the temperature measured at the observation and recording control point is paid attention to
.

(5) Separately record the detection load from high temperature (or ultra-low temperature) machinery and equipment to ultra-low temperature (or high temperature) machinery and equipment to the control point of the machine and equipment measurement temperature repair to detect the temperature situation before the load release of the person in the short term
