Multimeters are quite helpful in testing problems in electrical connections and dealing with circuit issues. However, most of the multimeters are designed in a way that they can measure circuit characteristics such as voltage, current and resistance but many of the new models are capable of doing more. There are analog as well as digital multimeters available in the market, but the digital multimeters are the ones that are widely popular and in demand among the technicians.
The modern digital multimeters
The modern multimeters as the multimeters are referred to these days have evolved to become quite accurate. The accuracy feature is the main part because of which using digital multimeters makes more sense than using the analogue ones. As the digital ones are quite fashionable they also come with a lot of skilfulness, with features like auto-ranging and auto polarity.
Applications of a multimeter
A multimeter is capable of performing the following applications:
- Auto polarity.
- Tests continuity
- Measures duty cycle
- Eliminates parallel error
- Allows measurement of time and frequency.
- Advanced measurements such as capacitance can be performed.
Why use a multimeter?
Well, there are a number of pros of a multimeter for the technician because of which it should be used.
- Accuracy- A multimeter, especially a digital multimeter is known to be highly accurate. It is capable of showing reading in 4 decimals. Moreover, if the fluctuation is in range then it is considered to be okay.
- The auto polarity- One of the best reasons for using a multimeter is its auto polarity function, which means that it read both the positive as well as negative values. Reading negative values comes handy; using the digital multimeter becomes convenient with the auto polarity option.
- The auto-display function- Gauging the readings is not quite a big deal but a digital multimeter uses 7 segment displays to show the reading on the LCD screen. No longer do you need to keep an eye on the pointer to read the values.
- Current checking- A technician can manage the current from the highest available range to the desired range.
- The continuity check- This feature helps one to check the broken wire or a loose connection in an electronic device. If everything is right then the multimeter will release a beep sound.
- Measurement of the duty cycle and the capacitance- A multimeter has the ability to measure the duty cycle, in order to check any kind of distortion. In order to test the capacitance, one just needs to make sure that the capacitor is properly charged.
- Resistance checking- Multimeter allows resistance checking, and it can be done by using the diodes. This feature of checking the diode in a multimeter lets one determine where the diode should go.
From checking minor faults to the troubleshooting of the circuits, a multimeter is capable of doing everything, in fact, more than an analog multimeter can do. So, the pros of multimeter for a technician are many, which is why using it is quite necessary.
