1.Safety signs, packaging and transportation
5.1 safety signs        safety warnings

5.2 packaging

                                  

Do not put in layers, handle with care, waterproof, upward

5.3 transportation

In the state of transportation or storage packaging, the equipment must be able to be stored for less than 15 weeks under the following environmental conditions.

Ambient temperature range: - 20 ~ + 60 ℃.

Chapter II installation and commissioning

1. Safety criteria

1.1 before installing, repairing and maintaining the equipment, the installation technicians and operators must read the operation manual carefully.

1.2 before using the equipment, operators must carefully read gb2626 and be familiar with the relevant provisions of the standard.

1.3 the equipment must be installed, maintained and used by specially responsible personnel according to the operation instructions. If the equipment is damaged due to incorrect operation, it is no longer within the scope of warranty.

2. Installation conditions

Ambient temperature: (21 ± 5) ℃ (if the ambient temperature is too high, it will accelerate the aging of electronic components of the equipment, reduce the service life of the machine, and affect the experimental effect.)

Environmental humidity: (50 ± 30)% (if the humidity is too high, the leakage will easily burn the machine and cause personal injury)

3. Installation

3.1 mechanical installation

Remove the outer packing box, carefully read the instruction manual and check whether the machine accessories are complete and in good condition according to the contents of the packing list.

3.2 electrical installation

Install power box or circuit breaker near the equipment.

In order to ensure the safety of personnel and equipment, the power supply must have reliable grounding wire.

Note: the installation and connection of power supply must be carried out by professional electrical engineer.

Chapter III test operation

1. Equipment calibration

In principle, the equipment needs to be calibrated once a year. Specific calibration can be entrusted to metrology institute or contact us.

2. Test environment

Temperature: 20 ± 5 ℃, humidity: 50 ± 30%.

Please be sure to keep the temperature and humidity, otherwise it will affect the accuracy of the test.

3. Test preparation

Several replaceable filter elements.

4. Operation steps

4.1. Connect the power supply and turn on the power switch.

4.2. Put the test sample into the test box, and only one sample is allowed to be placed in each small cell, and six samples can be placed at most.

4.3. Set the vibration time to 20s.

4.4. Press the start button to start the vibration and start to vibrate at a certain speed.

4.5. After 20 minutes, the vibration will stop automatically.

4.6. When the time is up, take out the sample and conduct subsequent detection.

4.7. Vibration is a pretreatment test item.

4.8. If it is necessary to test again, please follow the steps. If not, please turn off the power supply and carry out equipment maintenance.

5. Result judgment

Vibration is only a pretreatment item of relevant tests, and there is no final test data.

6. Precautions

6.1. It is forbidden to touch the equipment after vibration is started.

6.2. Although the vibration is cushioned, the vibration may make a loud noise, so it is recommended that the test room be large enough.

6.3. Before each test, check the support between the vibration box and the bottom support plate. Replace it in time if necessary.

6.4. In case of emergency, please cut off the power immediately and conduct the test again after finding out the cause.
