Floor Screws

Drain can be organized in two ways: * The drain hose can be hung on the edge of the sink or tub with a plastic guide, which included delivery of a washing machine. But it is important to ensure that the hose was not in the water, because in such a situation arises effect of 'pulling the water', as a result it begins to fill and drain the excess water at the same time * tie-in drainage. Box easiest to implement by organizing a sink in the siphon washbasin or sink. To do this, sometimes it is necessary to buy a new trap, or a separate item for the siphon, which has an additional input for the hoses on washing machines and dishwashers. This connection is also possible to "siphon effect" (drawing water), to prevent it in the drain hose valve must set (sold in hardware stores). Before starting the machine need to unscrew the shipping screws.

Transportation screws on the back wall, they can be from 2 to 4 pieces. After unscrewing the shipping screws should remove the back cover to remove the clamps, located between the tank and the rear wall, and into which these screws are fastened. Also, in some models inside, on either side are the seals, they must also be removed. To facilitate this step look at the instructions, usually in It has diagrams and pictures that illustrate the process of preparing a washing machine to the first wash. And the last point – the alignment of the machine with feet and level. An important condition – all four feet must be stable on the floor, and deviation from the horizontal should not exceed 2 degrees, otherwise the stabilizing mechanism will not work and the car will be noisy and vibrate excessively during the spin cycle. If the floor is installed on the machine, springs, control should be especially accurate. It is impossible in such a situation underlay under car rubber mats or other soft cover, it is better to use a thick sheet of plywood or particleboard. But if you're not confident in their ability or are faced with difficulties in connecting the washing machine, do not forget that there are professionals who are ready to quickly and accurately carry out this work.

Electronic Counting Scales

Libra is a measuring instrument and intended for the calculation of weight. Weight is measured by such a unit, as pounds, as well as its derivatives, such as tons, grams, milligrams, etc. Due to the fact that it is absolutely accurately measure the weight of unrealistic, then the weights of evidence can be considered valid with a certain margin of error. On the other hand, indications of the weighing results in the display of electronic scales are reproduced with certain increment, denoted by the value d. For example, the display shows the trade weights 1 kg, by adding a weight of 3 grams of readings will be equal to 1.005 kg, ie will change in increments of d = 5, many mistakenly believe This quantity d is the measurement error weight. However, it is not. The maximum permissible error of measurement determined by the price verification scale – a special metrological value is usually a manufacturer of weights guarantee ratio: d = e. This equation allows us to establish the connection between discrete readings and measurement error.

Also of importance are the highest metrological characteristics (IVC) and smallest (NmPV) limits weighing. Beyond these limits the testimony of weights are accurate. Electronic scales of high accuracy measurements can not be simultaneously a large value of the NIP. Decide first what you have more important. For accurate weighing is best to stay in balance with a smaller value of e and a small IVC, respectively. Model selection is influenced by a number of functional features: a set of scales implemented in functions, constructive (external or built-in indicator, etc.), type of food, an interface, the operating conditions – a number of models produced at a higher dust-and waterproof performance or load cell and a platform from stainless steel. When choosing, make sure you include whether the required functions for standard or options.

As an example of neglect of metrology measurements can be weighted to bring the literal use of consumer so-called counting function of electronic scales. This feature is available in countable models of scales CAS CS, SC, AC and is a two-step process, first calculating the average weight of similar products (by determining the weight of a sample of a certain number of them), and after – an unknown number of them in the working portion of its weight. In the advertising material from time to time give the result of counting up to things, does not indicate what a real piece error calculations. Naturally, the claimed accuracy – the formal result obtained by the microprocessor when the weights of an arithmetic operation of division. Therefore, the interpretation of results measurement should be a specialist with expertise related to mathematical statistics and possession of a priori information about the statistical properties of weighted items. Counting scales, in this case, play supporting role.
