Uses of a Multimeter And Its Comparison With a Sinometer

The digital multimeter is a versatile instrument that is used to get various types of electrical measurements. These are simple to use and are commonly used in testing and debugging electronics or electrical circuits. These can be used for various applications and can function as voltmeter, ammeter, and ohm meter in one device. Though the basic hand held digital multimeters are adequate for simple electrical measurements for accuracy and functionality, advanced versions such as NI 4070 FlexDMM are used. These gadgets have 6½ digits of precision and all the functionalities of stand alone high-voltage digitizer, which can acquire waveforms at sampling rates up to 1.8 MS/s at ±300 V input.

To Measure Currents:

A digital multimeter can serve as ammeter when placed in series with a current flowing wire or electrical component. When it is used as an ammeter, the digital multimeter will have only a negligible resistance, which will cause a very small voltage drop across the multimeters leads. There are various digital multimeters, such as the NI 4070, which are capable of testing both AC and DC currents.

To Measure Resistance:

It can also be used as an ohmmeter to measure resistance of an electrical component. The terminals are connected across the electrical component, whose resistance is to be measured. When switched on the digital multimeter develops a small known voltage between its terminals and when a resistor is connected across these terminals a current will flow, which can be calculated using Ohm’s Law. Some digital multimeters like the NI 4070 are used to measure both 2-wire and 4-wire resistance measurements.

To Measure Continuity:

A digital multimeter is a convenient option to measure continuity between two points of a circuit and to track circuit breaks. Digital multimeters, such as the NI 4070, have a continuity setting that will map the flow of current between any two points. A continuity test can be done also by measuring the resistance in cases where the multimeter does not have a continuity setting.

To Measure Frequency:

Some can also be used to measure the accurate frequency, which is a crucial parameter for electrical devices that work on a steady AC voltage. Frequency can be easily measured by attaching the positive terminal to the electrical component with the signal and the negative lead to ground.

A sinometer is a new AC/DC Auto/Manual Range meter, which has many advanced features. Both multimeters and Sinometers can be used to test AC/DC Voltage and Current, Resistance and Capacitance. The major difference is that in Sinometer there is a provision to test inductance as well. The Sinometer has sound and light warning for the jacks and back-lit LCD Screen, which makes these more user friendly and simple.

To get an overview of the latest models in digital, b2b market places will be the best possible options as it enables you to come face to face with the various vendors and suppliers in this field. This will also ensure a wonderful opportunity to know about overseas trade fairs and exhibitions as well.
