The multimeter, also known as a VOM, can measure voltage, resistance, and current. It exists in two forms, analog and digital. The analog multimeter uses a needle that moves across a scale to indicate measured values. The digital multimeter uses buttons to select functions and ranges and displays numeric readings. Both types are zeroed before measurements and have probes to connect to circuits under test.
The Multitester
- 2. sometimes called the VOM (voltmeter, ohmmeter, milliammeter). It is the best instrument that can measure voltage, resistance and current. It is generally made of two types: the analog and the digital.
- 5. The needle-shaped rod that moves over the scale of a meter. It is mechanically connected to the moving coil. It indicates the measured values on the multimeter scale.
- 6. makes it possible to select different functions and range of the meter.
- 7. makes it possible to adjust the pointer to the zero position of the scale.
- 8. a series of marking used for reading the value of a quantity
- 9. can have different types of scale, for voltage and current readings the scales have mostly linear which means equal division. For resistance readings, the scale have logarithmic which means unequal divisions.
- 10. Is used to zero-in the pointer before measuring resistance.
- 11. is used to connect the circuit to the electrical components being tested
