During the temperature control process of the high and low temperature test box, when there is a large temperature overshoot or a large temperature fluctuation, the engineer usually recommends to reset the parameters in the instrument, which is what we call the self-tuning function. So what are the specific steps?
a. Turn off the high and low temperature test box power switch, open the door to allow the equipment to naturally cool to ambient temperature;
b. Close the door, open the power switch, set the temperature to the usual temperature value;
c. According to the control parameter adjustment method, the self-tuning parameter is adjusted to 1;
d. Under normal working condition, press and hold the down button for 5 seconds to enter the auto-tuning state. At this time, the PV display shows ATU and flashes;
e. After the self-tuning is finished, the meter automatically returns to the normal working state;
f. In the auto-tuning state, pressing any key is invalid.
