Oven proper use instructions

The use of oven
1. Use of environmental requirements:
a) Temperature: 5 ~ 40 ℃
b) Relative humidity: ≤ 85% RH
c) Power supply voltage: AC220V ± 10% 50Hz
d) four weeks without a strong vibration and corrosive gases affect
2 vacuum debugging:
a) The box door and tighten the door handle in place, closed discharge valve (the rubber stopper holes with the holes on the release valve twisted partial 90 °), open the vacuum valve (by the counterclockwise rotation 90 °), the first time you use the vacuum valve switch may be tight, be forced to rotate.
b) Using random accessories vacuum connection tube (inner diameter: Φ16mm thickness: 10mm) vacuum drying oven exhaust pipe (diameter: Φ16mm) and a vacuum pump (2XZ-2 type, the inlet diameter Φ16mm) connected securely (6090 and 6210 already connected). Vacuum pump connected to the power and began pumping seriously empty table indicates values ??reached-0.1Mpa, the first closure of the vacuum pump valve closed after power to prevent vacuum pump oil to flow back into the studio, this time in a vacuum chamber.
3 oven vacuum box debugging:
In the vacuum, after debugging, can be manipulated as follows:
a) Turn the vacuum chamber, and the Power LED should light. Power On Self Test temperature controller, PV display the working chamber measuring temperature, SV display is factory set temperature. Temperature control device on the AT and HEAT and other lights should be lit, heated instrument to enter the working state.
b) to modify the set temperature oven
1 Click temperature controller function key (SET); PV display SP characters, the available key head button to set the temperature changes.
(2) After modification, press the SET button, PV display ST characters, set the timer time.
 If you do not use the timer function, you can still let ST = 0
3 Press the SET button, the screen display studio temperature PV, SV screen displays the new set temperature. AT AND HEAT instrument lights, then re-enter the meter heated working condition.
c) When operating the indoor temperature close to the set temperature, HEAT lamp light suddenly flickered, which means that the heating stage to enter the PID regulator, the instrument is sometimes measured temperature exceeds the set temperature, sometimes below the set temperature is normal. When measuring the temperature close to or equal to the set temperature, and then after the studio until 1 ~ 2h enter a constant temperature, goods enter the drying stage.
d) the desired temperature is low, the second setting mode can be used, such as the required operating temperature 70 ℃, the first time to set 60 ℃, and other temperature overshoot began to fall, and then the second set 70 ℃ , so that the temperature can be reduced or even Du do overshoot, as soon as possible to enter a constant temperature.
e) when the goods drying is complete, turn the power off, if accelerated cooling, then open the bleeder valve so that the vacuum is 0, for 5 minutes or so call box door.
(4) If the working chamber of dry matter humidity, water vapor generated will affect the performance of the vacuum pump is recommended between the oven and the vacuum pump, string into a "Dry / filter."
5 If the drying process of the article, you need to add nitrogen and other inert gases, should be specified in the contract, was equipped with an inlet valve.
(Note: 1. If the pump properly and meet the technical requirements, can not vacuum, then open the door to use the product in the annex to wrench the door button on the box screwed to the inside circle to close short, re-close the door. 2 This vacuum oven can not be used as an electric oven, because the studio is not in a vacuum state, measuring the actual temperature and the working chamber temperature error great)
