Electric blast drying oven use and precautions
First, use and operation:
1. Before powering on, check the electrical performance of the box and pay attention to whether there is a short circuit or leakage.
2. Adjust the automatic thermostat according to the test temperature requirements, then adjust the temperature switch and insert the thermometer into the air hole to observe
Check the temperature inside the box.
3. Connect the power to turn on the “switch 1†(a group of heating wires to heat up). If you need high temperature, you can turn on “switch 2†(the two groups heat up at the same time), turn on the blast switch, and the blower works.
4. When the temperature rises to the required temperature, the red and green lights alternately jump and jump into a constant temperature state.
5, to observe the studio sample, you can open the box door, observe the glass door inside the box, but the box door is not always open, so as not to affect the constant temperature.
6. When taking the sample and opening the glass door, the hand should have protective measures to prevent burns.
Second, maintenance and maintenance:
1. The cabinet should be placed in a dry and stable place with no vibration or corrosive gas around. The ambient temperature is generally not more than 40 degrees, and the relative humidity of the air is not more than 85%.
2, the electrical contact thermometer lead, near the terminal, must be clean, not wet, remember to contact with acidic goods.
3. Do not damage the anti-corrosion paint layer in the workroom to avoid rusting the cabinet.
4. This box is not an explosion-proof box, so it has volatile items. Do not put it in a dry box to avoid explosion.
5. Once the electronic controller fails, the power supply should be disconnected immediately, and a comprehensive inspection should be carried out. The controller semiconductor must reach a certain level.
If it fails after an hour, it should be replaced immediately.
6. The maximum average load of the sample shelf is 15kg. Do not put the sample on it. The working plate (ie the heat sink) cannot be placed.
Set the test.
