Maintenance + Tips Teach you how to use your DV well in winter
The first tip to pay attention to in winter: Prevent cold
DV is a precision electronic product, and its working circuit can only work at normal temperatures. In weather below zero degrees Celsius, the machine is likely to shut down. Without the camera, moisture in the air will condense on the integrated circuit components, causing a very serious short circuit. Therefore, when shooting outdoors in winter, you must pay attention to keeping the DV warm and dry. If necessary, you can wrap a small piece of clothing around the DV, especially when operating in a sub-zero environment.
However, you should also be careful not to overdo it even if you want to protect yourself from the cold. In order to protect yourself from the cold, some friends hold their DV in thick clothes while shooting. Over time, the machine will also overheat. The working condition and service life of the hard disk have a great relationship with the temperature. The appropriate temperature for the hard disk is 20~25℃. If the temperature is too high or too low, the clock frequency of the crystal oscillator will change. In severe cases, it will also cause damage to the circuit in the hard disk. If a component fails, the storage medium will also cause recording errors due to thermal expansion, so be sure not to let the machine work in a non-ventilated environment for too long.
Pay attention to the second tip in winter: Moisture-proof
Maybe you will say: "Winter is very dry, so don't worry about moisture corroding the DV, right?" In fact, you still need to pay attention, first of all in Guangdong It often rains in winter and is not as dry as you think; secondly, there is a big temperature difference between indoors and outdoors in winter. If you bring a DV with a higher temperature from indoors to the outdoors suddenly, or from a cold outdoor, you suddenly bring a DV with you. Entering a warm room may cause water vapor to condense inside the DV. You can imagine the consequences.
The solution is also very simple: Generally speaking, the easiest way is to put the DV in the camera bag and carry it for storage. If the thickness and sealing of the bag are not good, you can put the DV in a plastic bag. It does not need to be too thick and the air in the plastic bag can be gently removed. The purpose of this is to isolate moisture in the air and keep the machine storage environment dry.
Pay attention to the third tip in winter: Protect the hard drive
In addition to preventing low temperature from damaging the hard drive in the DV, shockproofing is also a very important part. The disadvantage of the hard drive is that it is afraid of sudden and violent vibrations, especially when turning on the computer. The hard disk is a very precise storage device. During read and write operations, the floating height of the magnetic head on the surface of the disk is only a few microns. Never shake the DV violently to avoid collision between the magnetic head and the disk and scratching the magnetic layer on the surface of the disk.
Although many hard-disk DV manufacturers now promote that their products have so-called "collision resistance" or "shock-proof system", they all refer to shock-proof and anti-collision when the hard disk is not in use. ability, not when it is turned on, so everyone must "handle it with care" when using it, and don't think that everything will be fine with the shock-absorbing design.
Pay attention to the fourth tip in winter: Protect the lens
DV’s optical lens is relatively delicate, so a UV lens must be equipped. A lens cover alone is not enough. Even an automatic lens cover cannot truly protect you from rain and snow. UV mirrors are very convenient to use. Even if they are dirty, they are easy to wipe. If they are seriously damaged, you can replace them. The price is much cheaper than lenses.
In addition, if there is no need to use UV, sometimes the original factory also provides protective glasses, which are the same as UV glasses except that they have no anti-UV function; in addition, in places with strong sunlight, you can also consider CPL polarization When you use a mirror, the effect you take will be different.
Pay attention to the fifth tip in winter: Protect the battery
Lithium batteries have a big disadvantage: they are not suitable for long-term work and storage at very low temperatures. If under such circumstances, the activity of electric ions in the lithium battery decreases, so the power supply is much less than at normal temperature. The battery should be removed from the machine when not in use, and the battery should be placed in a pocket to maintain temperature. Pay attention to regular Charging is helpful to maintain the working life of the lithium battery, and it is also helpful to keep the DV in a working state at any time.
If you need to go to the north to shoot icy and snowy scenes, it is recommended that you buy a compatible battery from another brand as an alternative. In this way, even after harsh shooting in the wild, the battery will not be as good as before, and it will still be better than the original one. It's much more cost-effective to sacrifice the battery.
