The hardness tester is a combination of mechanical and liquid crystal
.
Like other precision electronic products, under our careful maintenance, its performance can be fully utilized and its service life can be longer
.
The following is an introduction to how to maintain and maintain the hardness tester in the daily use process, roughly in the following four aspects
.
1.
Pay attention to "Handle with care.
The mobile hardness tester should be handled with care, and pay attention to the packaging and shock resistance
.
Because most hardness testers use LCD liquid crystal panels, if there is strong impact, extrusion and vibration, it may cause the LCD panel.
The movement of the position will affect the convergence of the image during projection, and the phenomenon that the RGB colors cannot be overlapped
.
At the same time, the hardness tester has a very precise optical system.
If there is vibration, the lens and mirror in the optical system may be displaced or damaged.
, affecting the projection effect of the image, and the zoom lens may also be stuck or even broken under the impact.
Second, the use environment The cleanliness of the use environment is a common requirement for all precision electronic products, and the hardness tester is no exception, and it is not an exception to the environment.
The requirements of the hardness tester are higher than other products
.
We should place the hardness tester in a dry and clean environment, away from humid places, and pay attention to indoor ventilation (it is recommended to use it in a smoke-free place)
.
Small, but high resolution, any fine dust particles may affect the projection effect
.
In addition, the hardness tester is generally cooled by a special fan at a flow rate of tens of liters of air per minute, and the high-speed airflow After the dust filter, there may be tiny particles entrained
.
These particles rub against each other and generate static electricity and are adsorbed in the cooling system, which will have an impact on the projection screen.
At the same time, too much dust will also affect the rotation of the cooling fan, causing the hardness tester to overheat.
.
Therefore, we need to clean the dust filter at the air inlet frequently
.
Since the LCD panel is sensitive to temperature, it is necessary to keep the hardness tester in use away from the heat source while preventing moisture and dust from being damaged to prevent the LCD panel from being damaged
.
3.
Precautions for use 1.
Pay attention to the nominal value of the power supply voltage, the ground wire of the hardness tester and the polarity of the power supply, and pay attention to the grounding
.
Because when the hardness tester and the signal source (such as a computer) are connected to different power sources, there may be a high potential difference between the two neutral lines
.
When the user plugs and unplugs the signal wire or other plugs under power, fire will occur between the plugs and sockets, which will damage the signal input circuit, which is likely to cause damage to the hardness tester
.
2.
During use, the hardness tester should not be switched on and off frequently, because this may damage the equipment components inside the hardness tester and reduce the service life of the bulb
.
3.
The refresh rate of the input source cannot be too high.
Although the refresh rate of the input signal source is very high and the image quality is very good, when using the hardness tester, we also consider the refresh rate of the computer monitor it is connected to
.
If the two are not consistent, the signal will be out of sync and cannot be displayed
.
This is why there are often pictures that can be played normally on the computer but cannot be projected through the hardness tester
.
4.
Maintenance of the hardness tester The hardness tester is a precision electronic product.
When it fails, unless you are a very good expert, you should not start the test without authorization, but seek help from professional technicians
.
The above is the introduction of the precautions for the use of the hardness tester.
I believe that everyone has a corresponding understanding of this after reading it.
You can use it as a reference and hope it will be helpful to you
