After the vacuum degree debugging is completed, the following five operations can be performed: 1.
Turn on the power supply of the vacuum box first.
At this time, the power indicator light should be on, the temperature controller is powered on for self-checking, the PV screen displays the measured temperature in the work room, and the SV screen displays the factory setting.
The temperature set at the time; the lights such as AT and HEAT on the temperature controller should be on, indicating that the instrument has entered the working state of heating
.
2.
Modify the set temperature and time 1.
Press the function key (SET) of the temperature controller; after the SP character is displayed on the PV screen, you can use the arrow buttons to modify the set temperature 2.
After the modification is completed, press the SET key again, The PV screen displays ST characters, and the timing time can be set.
If the timing function is not used, ST=0.
3.
Press the SET button again to make the PV screen display the studio temperature, and the SV screen to display the new set temperature; the meter AT and HEAT lights are on, and the instrument re-enters the working state of heating
.
3.
When the temperature in the work room is close to the set temperature, the HEAT light flashes on and off, indicating that the heating enters the PID adjustment stage.
The instrument sometimes measures the temperature over the set temperature, and sometimes it is lower than the set temperature
.
When the measured temperature is close to or equal to the set temperature, the studio will enter a constant temperature state after 1~2 hours, and the item will enter the drying stage
.
4.
When the required temperature is low, the secondary setting method can be adopted.
For example, the required working temperature is 70 °C, the first setting is 60 °C, and after the temperature overshoot begins to fall back, the second setting is 70 °C, so that It can reduce even the temperature overshoot phenomenon and enter a constant temperature state as soon as possible
.
5.
When the items are dried, turn off the power.
If you want to speed up the cooling, open the air valve to make the vacuum degree 0, and then open the door after about 5 minutes
.
