Advantages and disadvantages of digital multimeter
Following are the advantages of digital multimeter : They are having high input impendence, So there is no loading effect. They are having higher accuracy. An unambiguous reading is obtained. The output can be interfaced with external
Ohmmeter
The meter which measures the resistance and the continuity of the electrical circuit and their components such type of meter is known as the ohmmeter. It measures the resistance in ohms. The range of a megger may extend to more
What is ohmmeter?
The ohmmeter is a convenient direct reading device for measurement of resistance. The purpose of an ohmmeter is to measure the resistance placed between its leads. This resistance reading is indicated through a mechanical meter movement which
Advantages and disadvantages of electronic multimeter
There are some advantages of electronic multimeter which are given below, The input impedance is high. The frequency range is high. The construction is rugged. The circuit is simple. It is less suffered from electric noise. The
Capacitor testing with ohmmeter
Three capacitor defects are detectable with an ohmmeter are short, open and partial short. If the capacitor is in a ciruit, it must be separated by disconnecting one lead. The shorted capacitor has a dilectric breakdown. When
Well type monometer
The well type monometer is widely used because of having only one leg. The main difference between a U-tube manometer and a well type manometer is that the U-tube is substituted by a large well such that
How pressure is measured with inclined monometer?
The inclined type monometer is an enlarged leg monometer with its measuring leg inclined to the vertical axis by some angle. Due to inclination, scale expands and increases the sensitivity. When P1 and P2 are applied, then
Difference between radiation pyrometer and optical pyrometer
There is difference between radiation pyrometer and optical pyrometer is given below. Radiation pyrometer Optical pyrometer Temperature is direct measured with the help of thermocouple. Temperature is measured by comparing the brightness of hot body radiation at
