14.1.2. Measuring devices
Measuring devices available on sale differ among themselves mainly with a range and accuracy of measurements. By a measurement range it is established, in what area there should be registered pressure and resistance.
At measurement of resistance the device, as a rule, is limited to a range in kiloohms, In addition to it measuring devices are applied to check of electric and electronic elements of a design. They allow to spend wide measurement from small resistance in Ohms up to мегаОмного a range. Very precisely it is possible to measure pressure () that first of all it is required for check of electronic elements of a design. If it is necessary to check up only, whether pressure (V) the simple control bulb for this purpose approaches () moves in general. However, it is valid only for those electric chains in which there are no electronic details. Nevertheless electronic details extremely sensitively react to too high currents. Under certain circumstances they can fail even at connection of a control bulb. The prevention |
