a. Turn on the vacuum drying oven power supply. At this time, the power indicator light should be on 6090 and 6210. The temperature controller should be turned on separately. The PV screen displays the temperature measured in the working room. The SV screen displays the factory setting. temperature. The AT and HEAT lights on the temperature controller should be on, indicating that the instrument enters the warm working state. b. Modify the set temperature of the vacuum drying oven 1. Press the function key SET of the vacuum drying oven temperature controller; after the SP screen displays the SP character, the key temperature can be modified by the button button. The 6090 and 6210 models should be set separately for the 2 and 3 instruments. Similar. 2. After the modification is completed, press the SET button again, the PV screen displays the ST character and sets the timing time. If you do not use the timing function, still let its 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 meter re-enters the warming state. c. When the temperature in the working chamber of the vacuum drying oven is close to the set temperature, the HEAT light will be dimly lit and dark, indicating that the heating enters the PID adjustment stage. The meter sometimes measures the temperature exceeding the set temperature, and sometimes the temperature below the set temperature is normal. When the measured temperature is close to or equal to the set temperature, the studio enters a constant temperature state after 1~2h, and the item enters the drying stage. d. When the required temperature is low, a secondary setting method can be used, such as the required working temperature of 70 ° C, * first set 60 ° C, the temperature overshoot starts to fall back, and then the second time is set to 70 ° C, This can reduce or even eliminate the temperature overshoot phenomenon and enter the constant temperature state as soon as possible. e. When the item is dry, turn off the power. If the temperature is lowered, open the air release valve to make the vacuum level 0. Wait about 5 minutes to open the door of the vacuum drying oven . 4. If the humidity of the dry matter in the working chamber is large, the generated moisture will affect the performance of the vacuum pump. It is recommended to insert a “drying/filter†between the drying box and the vacuum pump.
