Ask for the instruction manual of the moisture proof cabinet, the common faults and solutions of the

Alas, the moisture-proof cabinet instruction manual, go to our space to see

What brand and what model you are using I don't know how to tell you.

What should you pay attention to when using a moisture-proof box?

1 Do not install the machine near the source of electromagnetic disturbance.

2 Please do not use and store the machine in the open air, high temperature and humidity conditions.

3 When the equipment is overhauled, please shut down the machine and block the power supply to prevent electric shock or short circuit.

4 The equipment is installed in a place where it is balanced and cannot be tilted or unstable.

5. If the use is suspended, in order to protect the equipment, it is recommended to turn off the main power supply of the equipment.

6. The operation of the equipment must be operated by full-time personnel (trained) and correctly according to the operation instructions, and other personnel shall not operate at will.

7. When in use, do not press more than two buttons at the same time, otherwise, it will cause malfunction and affect the work.

8. Ensure that all parts of the equipment are grounded excellently.

Operational clarification. 1.The moisture-proof box must be placed on a level, solid surface. Roll your feet to a balanced position.

2.Leave a certain space on the north side of the moisture-proof box to facilitate exhaust, and the distance from the wall or other items is not less than 5cm.

3.Connect the cable, connect the mother and child in series on the host, and plug in the power supply (220V 50Hz).

4.The humidity can be set, and the product can be adjusted to the up and down buttons to adjust the humidity to the required value.

5.If you use it again after the first power supply and long-term non-use, please run the empty container for more than 12 hours, and admit that the humidity has dropped to a low level.

6.Open the door of the moisture-proof box, and write the corresponding cargo number after loading the material chip in an anti-static bag and put it on the partition in the moisture-proof box.

7.Close the door of the moisture-proof box and lock it, and the whole process of opening and closing the door is controlled within 1 minute.

8.When the item is placed in the moisture-proof box, the humidity in the moisture-proof box will rise due to the moisture contained in the object, and it may take 1 to 2 days for the humidity to drop.

Electronic moisture-proof cabinets (also called moisture-proof boxes, drying ovens, drying cabinets) are becoming more and more widely used. It is widely used in moisture-proof and anti-oxidation storage of semiconductors, raw materials, integrated chips, LED brackets, PCBs, precision components and other materials, finished products and semi-finished products. In the process of using the moisture-proof cabinet, it is inevitable that the fault will occur.

Due to its earlier origin, the electronic moisture-proof cabinet is currently used more. So, what are the main faults of electronic moisture-proof cabinets? How do you deal with it when you encounter it?

For the problem that the humidity does not drop or decreases slowly, it is mainly the problem of the dehumidification parts. In this case, first check if there is a problem with the humidity display, which leads us to mistakenly believe that the humidity of the humidity cabinet does not drop or decreases slowly. The second is to check the movement valve at the back of the moisture-proof cabinet to see if the valve cannot open and close normally due to the jamming of small objects.

In addition, it is to check whether the movement is heating up when the light is on. If there are these problems, except for the valve limb comic door jamming can be dealt with by ordinary engineers, the others need to be dealt with by the manufacturer. If none of the above problems appear, and the humidity of the moisture-proof cabinet still does not drop or decreases slowly, it may be that the molecular sieve material of the movement is aging, and the entire upper movement needs to be replaced in the sock hunger.

When using the moisture-proof cabinet, it is necessary to do a good job of daily maintenance in all aspects. How to maintain the moisture-proof cabinet? PChouse will take you to find out.

1. The drying oven of the moisture-proof cabinet should be placed horizontally in a dry and ventilated place without debris around, and the distance from the wall should not be less than 30cm.

2. Clean and maintain the moisture-proof cabinet regularly, take out the inner layer of the cabinet and wash it with a dry towel dipped in alcohol. When cleaning the moisture cabinet, first unplug the power plug, wipe the inner and outer surfaces of the moisture-proof cabinet [drying oven] with a clean alcohol cloth, and prohibit washing the moisture-proof cabinet with water. If you are using a detergent scrub, you must use a dry cloth to dry off the water after wiping off the detergent with a clean, damp cloth.

When cleaning, be careful not to hit the dehumidifier and humidity detection device.

3. Always check whether the cabinet door seal is well sealed, so as not to affect the moisture-proof effect and product safety.

4. When using, if it is found that it is not dehumidified, or the "squeak" sound caused by the discharge of the dehumidification host cannot be heard, it means that the moisture-proof cabinet is faulty, and the power should be cut off in time to stop using it, and contact the company for after-sales inspection and maintenance.

The manufacturers of moisture-proof cabinets are ABMCDC, Hailio and Naboxsuna.

1. ABMCDC.

ABMCDC brand belongs to Zhuhai Biqier Business ****, the company was established in 2013, is a well-known enterprise mainly engaged in moisture-proof cabinets, moisture-proof boxes and drying ovens.

3. Silicon wafers.

4. Electronic components.

5. Liquid crystal glass substrate.

6. Optical film and lenses.

7. Quartz vibrator.

8. Storage of precision instruments and meters.

9. Other electronic components.

Capacity: 1250L

Shelves: Five standard shelves, the shelves are adjustable, and the space in the cabinet is reasonably allocated.

Color: Late debate white.

Electric voltage: 220V

Precision: 3%RH, 1

Software: Humidity Manager V2, providing digital temperature and humidity curve drawing function (optional).

Cabinet structure: made of 1mm thick steel plate, high-strength cabinet body, no deformation, no air seepage, the whole cabinet powder baking paint.

Door style or: 5mm tempered glass and high-strength handle.

Caers: Four sets of 3-inch casters, and two of them are provided with braking function.

(1) Whether the humidity setting method is correct.

1.The symbol of 8888 appears on the display panel, please re-plug the client (the computer system is crashed), if the re-plug is still the same, then send someone to repair.

2.The display panel digits are jumping too slowly (the delay time is too long).

1) This is caused by the position relationship of the sensor line, which avoids frequent opening and closing of the door and affecting the accuracy of the instrument.

2) There are many items in the cabinet, resulting in low convection.

3.The temperature and humidity accuracy is incorrect.

Treatment: aFind out if the last instrument calibration has been more than one year, if so, you need to arrange a time to re-calibrate (disassemble and recalibrate).

b.The customer tests the instrument, the date of calibration, and whether it is fair (it should be calibrated more than once a year).

c.The humidity at the test instrument point will react differently.

Different temperatures of the test instrument will also have different humidity results.

Humidity is relative humidity, which is for temperature, such as 29 degrees and 31 degrees Celsius, the relative humidity value displayed is different (different temperatures have different saturated water vapor pressure, and the humidity value contained is relatively different).

Different test locations will also have different results.

For the 315 cabinet, the error value of the test instrument at the bottom of the cabinet will be 4 to 5%, and the error value will be 1 to 2% when placed on the top, which is within 20 minutes in the short term, and the test must be tested in the same position as the senor, and the value that can be obtained can be closer to the LED.

d.Corrosive or acidic volatiles can also cause LED failures.
