Operating temperature
The ideal operating temperature of the cash register should be 10-35 degrees Celsius. Too high or too low temperature will affect the life of the cash register accessories. High-temperature damage to the cash register is mainly caused by temperature-sensitive accessories such as CPUs, monitors, and motherboards. For example, CPU, the maximum working temperature should not exceed 80 degrees Celsius. If the CPU works at an ultra-high temperature for a long time, it will not only shorten the life of the cash register, but may even burn it. Therefore, it is very important to cool the CPU. In addition, it is best to install the temperature monitoring software. When using the cash register in the summer, pay attention to indoor ventilation and cooling.
environment humidity
For the cash register, the relative humidity is 30%-80%. If the humidity is too high, it will not only affect the performance of the cash register, but also cause dangerous situations such as short circuit due to moisture, which will seriously burn the motherboard. Therefore, in the case that the air is too humid (especially in the southern rainy weather) or continuous rain, even if it is not necessary to use the cash register due to certain circumstances, it is necessary to start the operation at intervals. In addition, do not use the cash register with wet hands, or wipe the cash register with a cloth dampened with water, especially at the line interface. Conversely, the weather is too dry and not good because it is prone to static electricity and is also harmful to cash register accessories.
Environmental dust
Since the cash register chassis is not completely sealed, and the static electricity generated when the cash register operates, it has a dust suction effect and is very susceptible to dust. When dust is attached to the surface of the integrated circuit board, it may cause poor heat dissipation, which may cause a short circuit of the motherboard circuit. For the display, small dust may cause high voltage ignition inside the display and there is a danger of burning. In addition, like the soft keyboard, mouse, power fan and most accessories, it is also afraid of dust.
Shock and impact
Vibration can cause the cash register accessory interface to detach from the circuit components, resulting in poor contact. And this is a problem that is not easily detected. The impact will cause irreversible hardware damage to the cash register and the parts must be replaced.
In addition, the use environment of the cash register also avoids environmental factors such as oil stains, acid etching and exposure. The cash register produced by a regular merchant can be used for ten years without considering the replacement.
