1、 Vacuum debugging method

調試前，我們需要關閉真空干燥機箱的門，擰緊門把手，然后關閉放氣閥，打開真空閥。當然，一次使用時，真空閥的開關可能很緊，可以用力旋轉。我們可以使用隨機附件進行真空連接管，牢固連接真空干燥的抽氣管和真空泵。當接通真空泵電源時，需要開始抽氣，當真空計的指示值達到-0.1Mpa時，需要先關閉真空閥，然后再關閉真空泵電源，以防止真空泵中的油倒流到工作室內，這時真空干燥器內部就處于真空狀態(tài)。

Before debugging, we need to close the door of the vacuum drying cabinet, tighten the door handle, then close the vent valve and open the vacuum valve. Of course, the switch of the vacuum valve may be very tight when it is used once, and it can be rotated by force. We can use the attached accessories to connect the vacuum pipe, and firmly connect the suction pipe and vacuum pump for vacuum drying. When the vacuum pump power is connected, it is necessary to start pumping. When the indication value of the vacuum gauge reaches -0.1mpa, it is necessary to close the vacuum valve first, and then turn off the power supply of the vacuum pump, so as to prevent the oil in the vacuum pump from flowing back into the working room. At this time, the vacuum dryer is in a vacuum state.

二、機內調試方法

2、 Internal debugging method

先打開真空干燥器的電源，然后它的電源燈亮起并進行自檢，然后此時也就表明已進入狀態(tài)。設定真空干燥機的溫度，設定機內的溫度接近指定溫度時，加熱開始進入PID調節(jié)階段，儀表測定溫度超過設定溫度，伸長也低于設定溫度是正常現(xiàn)象。

First turn on the power supply of the vacuum dryer, then its power light will light up and carry out self-test, and then it indicates that it has entered the state. Set the temperature of the vacuum dryer. When the temperature in the dryer is close to the specified temperature, the heating begins to enter the PID regulation stage. It is normal that the temperature measured by the instrument exceeds the set temperature and the elongation is lower than the set temperature.

因此，在測量溫度時如果已經(jīng)接近或等于設定溫度，再過1-2小時之后就幾乎可以進入恒溫狀態(tài)。如果需要的溫度比較低，我們可以采用二次設定的方法，讓它盡快進入恒溫狀態(tài)。

Therefore, if the measured temperature is close to or equal to the set temperature, it can almost enter the constant temperature state after 1-2 hours. If the required temperature is relatively low, we can use the secondary setting method to let it enter the constant temperature state as soon as possible.
