In fact, - it's still half the battle. It is very important to keep such equipment in working condition. Indeed, in fact it is fragile enough, and in order to keep it for a long time without repairs and reconfigurations, you need to use the device correctly.
To determine its use, you must first read the instructions. It is also important to understand what type the device belongs to, whether it is amateur, or professional. After all, if we are talking about a professional sample, it is worthwhile to understand that it will not have special sensitivity in terms of environmental indicators, that in any case it will give adequate evidence, and there should simply not be any problems with this. In addition, professional equipment makes it possible to check the condition of an entire company - or to do frequent tests without fear that the device will become unusable or begin to lie. If it comes to choosing - it is worth choosing professional equipment, even if it turns out to be somewhat more expensive than amateur equipment. The appliance for home use brings a minimum of benefit. Everyone who purchased such equipment in the past understood this very well. After all, some of the samples of such devices can be operated no more often than a couple of times a day. And others, even in this mode, do not give a 100% answer to all questions and can simply "substitute" their owner.
So, in order to keep your tester in proper condition, it is worth using a set of certain rules. Then he will not fail his owner. So, for example, you must always carefully follow the instructions - read it at least before you start operating the equipment. Then there will be much less problems.
It is important not to exceed the allowable number of measurements that can be performed over a certain period of time. Otherwise, the membrane deteriorates, and the device quickly becomes unusable.
Another important point is to use the device precisely at those environmental indicators at which it should be, which are indicated in the instructions. A professional device also has its own range of use. If you do not deviate from the set values, if you do not operate such equipment excessively and do everything in accordance with the instructions, you can achieve accurate readings from the device for many years.
