Step 1. Formulate the problem and identify ways to solve it. 
Quickly analyze the 
similarities with the current model of the device. Besides, it is necessary to take into account 
the measurement functions, it is certain that this model can become obsolete it should also be 
considered that new measurement methods will emerge to solve the problem. Before start 
searching for a measuring tool, it is recommended to describe in as much detail as possible the 
tasks one wants to solve with this tool. This will help you and the supplier to select the 
necessary equipment and its required configuration quickly and efficiently. Once the tasks are 
set, one can start looking for solutions to them. Don’t stop at one type of equipment or one

supplier. One can look through catalogs or websites of various manufacturers, visit exhibitions 
or seminars and get several alternative options from potential suppliers. Once a few alternative 
options have been selected, one can start choosing a specific device model directly. 
Step 2. Gathering data. 
It’s not enough to look at manufacturers ’catalogs and 
promotional booklets or attend supplier seminars to make the right choice. First of all, that the 
equipment offered to solve your problem may not provide with data of the most detailed 
information about its features needed to gather. The capabilities of any measuring instrument 
can be evaluated by three main parameters: 
Accuracy - whether a measuring instrument provides the required accuracy and stability 
of measurements under the right conditions. 
Efficiency - whether a measuring instrument can provide the required amount of work. 
Economic efficiency – the cost of purchased the device and maintaining work ability of 
it. Let’s now look at what criteria determine if a device meets these parameters.
