1. Maintenance Volume 1 1. Explosive, flammable and volatile materials should not be placed in the drying cabinet to avoid explosion.
2. The average load of the sample shelf should not exceed 15kg.
3. No items should be placed on the shelf between the sample chamber and the heating chamber, so as not to affect the heat exchange.
4. Before use, be sure to check whether there is overlap or short circuit of nickel winding.
5. The heating indicator is off, there are generally three reasons: â‘ the bulb is broken; â‘¡ the bulb is in poor contact; â‘¢ the heating system is faulty.
6. Turn on the heating switch without heating. There are generally four reasons: â‘ the nickel-chromium wire is broken; â‘¡ the switch is disconnected from the circuit; â‘¢ the temperature control knob is at the zero position (turn the temperature control knob to the specified temperature scale); â‘£ the relay is damaged.
7. There are three reasons for the temperature control failure: â‘ The temperature probe is damaged (replace the thermistor); â‘¡ The relay is damaged; â‘¢ The other components of the temperature control system are faulty (use a multimeter to detect the fault and repair it as appropriate).
Second, the first volume of maintenance two 1. Before using, you must pay attention to whether the power supply voltage used is consistent. When in use, the grounding wire of the power socket must be grounded as specified.
2. When using electricity, do not touch the electrical part of the space on the left side of the box with your hands or wipe it with a damp cloth and rinse with water. The power should be cut off during maintenance.
3. The power cord should not be entangled on metal objects, and should not be placed in a place with high temperature or humidity to prevent the rubber from aging and causing electrical leakage.
4. Do not squeeze the items in the box, and leave a space for natural convection of air, so that the humid air can escape on the wind roof.
5. Regularly check whether the silver contacts of the temperature regulator are fluffy or uneven. If so, use fine gauze to smooth the contacts before use. They should also be cleaned with a cleaning cloth frequently to make good contact (note that they must be cut off power supply). Do not hit the metal pipes of the indoor temperature regulator to avoid affecting the sensitivity.
6. Do not put flammable materials in the dry box without explosion-proof device.
7. After each use, the power supply must be cut off and the inside and outside of the box must be kept clean. Hang the corresponding logo after cleaning.
3. Maintenance Volume 1 1. Use of the instrument requires someone to be responsible. The external power supply should be cut off after the equipment is used to avoid accidents.
2. When placing the test product in the working room, it should not be too dense, so as not to affect the normal flow of airflow in the working room. There must be a 10-20mm gap between each item, and it should be placed symmetrically. The items on each shelf should be staggered. The distance between the bottom shelf and the bottom of the studio must be greater than 100mm.
3. There should be a certain space around the equipment to facilitate heat dissipation and operation and maintenance of the equipment.
4. Prevent sharp and sharp objects from scratching the device.
5. Please do not disassemble and disassemble electrical components and other parts of the equipment at will, so as to avoid damaging the electrical control circuit, causing human failure of the equipment and affecting its performance.
6. There is no flammable, explosive and corrosive materials around when storing and using the equipment.
7. It is forbidden to put flammable, explosive and volatile materials into this equipment for drying treatment.
8. Please read this "Product Instruction Manual" carefully before using the equipment, and then carry out various operations.
