Explosion models CT-C series hot air circulation oven use precautions
What problems should I pay attention to when using the CT-C hot air circulation oven?
1. Before use, it is necessary to pay attention to whether the power supply voltage used can be met. When using, it is necessary to stop the grounding of the power socket grounding according to the rules. 2. When using the power supply, avoid touching the electrical parts on the left side of the box with a hand or wipe it with a damp cloth and water. The power should be cut off during the inspection. 3. The power cord should not be wrapped around metal objects. It should not be placed in the center of low temperature or humidity to avoid leakage of rubber due to aging. 4. Do not over-extrude the contents of the box. It is necessary to leave room for natural convection in the atmosphere, so that the humid atmosphere can decelerate on the wind top. 5. It should reflect the silver contact of the temperature regulator in the current period whether it can be hairy or uneven. If it is, use the fine gauze to level the contact, then use it, and always wipe it with a clean cloth to make it contact well. Cut off the power). Do not impact the metal piping of the indoor temperature conditioner to avoid the flexibility. 6. Do not put flammable materials in the dry box without explosion-proof installation. 7. After each use, the power supply must be partially cut off, often insisting that the inside and outside of the box are clean. Clean the end and hang the corresponding logo. For details, please refer to the oven, dry box manual 2 1. Explosive flammable volatile items should not be placed in the dry box, so as not to cause an explosion. 2. The uniform load of the sample shelf should not exceed 20kg. 3. No objects can be placed on the shelf between the sample chamber and the heating chamber, so as not to affect the heat exchange. 4. Before use, it is necessary to reflect on whether there is stacking or short circuit of nickel wire. 5. The heating indicator light is not bright, the reason is usually three: 1 the bulb is broken; 2 the bulb is in poor contact; 3 is heated and fragmented. Maintenance and protection of electric drying box: 6. Turn on the heating switch without heating. The reason is generally four: 1 nickel-chromium wire breaking; 2 switch and line desoldering; 3 temperature control knob refers to the zero position (rotation temperature control knob to the specified temperature scale); 4 relay protection.
7. Temperature mastery failure, the reason is usually three: 1 temperature probe protection (change the thermistor); 2 relay protection; 3 temperature control system and other parts of the problem (using a multimeter to measure the problem, according to the situation).
