4, Environmental requirements

1. Room temperature: 0 ºC~40 ºC;

2. The relative humidity is not more than 80%;

3. There is no vibration, corrosive medium and strong electromagnetic interference around;

4. The fluctuation range of power supply voltage shall not exceed ± 10% of the rated voltage;

5. Correctly installed on a stable foundation. After the equipment is positioned in the factory, the customer needs to reposition the level and adjust the anchor bolts

5, Daily precautions

1. Please turn off the power when the machine is not in use.

2. When starting up, reset the emergency stop key, power on the machine (380V), and then start the system to enter the software test system

3. The air pressure range can be adjusted through the pressure regulating valve, which cannot be too large or too small. Please refer to the conventional cylinder push-pull gauge for specific conversion. It is recommended to use the pressure range of 0.2Mpa-0.5Mpa

4. The storage environment shall not be wet and the air circulation shall be good.

5. It shall be operated or supervised by special personnel to ensure safety.

6. When the machine is moving, do not touch the moving part with your hands to avoid danger.

7. The test speed cannot be set higher than the upper limit of the equipment speed, otherwise the test stability will not be guaranteed.

6, Maintenance items

1. During maintenance, please do not use water, alcohol or acetone to wipe, as this will damage the appearance of the tester and all electronic components will also be damaged.

2. Make sure the machine body is clean, and do not place it in a place with high humidity.

3. The coating part of the machine is often cleaned with a clean cloth.

4. Add a little engine oil to all moving parts (shafts, guide rails, parts that are often disassembled) for lubrication.

7, Quality assurance

1. Quality assurance matters:

The tester shall be free of charge for one year from the date of delivery (consumables are not included in the free scope)

2. In the following cases, although within the valid warranty period, the technology or material fees may also be charged:

·Damaged by natural disasters.

·Failure due to user's fault or operation error.

·Damage caused by failure to use the power supply voltage as specified.

·Dismantle and repair by yourself, even damage it.

·Lend it to others for use so that it breaks down.

·Self modification or even failure.

·Failure due to careless transfer or transportation.
