ANSWER

No. A DMM has a rated frequency.

Some DMMs are "true RMS" meters, which either means (a) they digitally sample the waveform at some relatively high frequency and perform the necessary math internally, or (b) they accomplish the same thing using an analog circuit. In either case, there is a maximum frequency they can accurately measure, because of the sample rate or because of the filter frequencies in the analog circuit. Typical meters can range from 1 kHz up to around 20 kHz.

Other DMMs do not make true RMS measurements. These make the assumption that the waveform is sinusoidal, so they merely rectify and filter the signal and then apply a scaling factor. The filters limit the applicable frequencies. These are often either very inexpensive meters, or are built specifically for AC power line measurements.

At some point, it's better to perform the measurement using an oscilloscope (with a high enough bandwidth).

It's not always easy to find the frequency rating for a digital multimeter. Not all manufacturers include it in the specifications.

What are the types of multi tester?

A Multimeter is an electronic instrument, every electronic technician and engineer’s widely used piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. There are two types of multimeters: Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. Digital Multimeter: We mostly used a multimeter is a digital multimeter (DMM). The DMM performs all functions from AC to DC other than analog. It has two probes positive and negative indicated with black and red color as shown in the figure. there are some best multimeters for HVAC.


Multimeter that can measure inductance capacitance frequency voltage current and resistance in one system?

Many mutlimeters have this capability. You'll probably want a digital multimeter. If you do a good search, this should be easy to find. You'll need to read through the specifications carefully to make sure you find one that gives the level of accuracy you're looking for. the more accurate it is, the more you'll pay.


What is better a digital multimeter or a volt ohm meter?

'Multimeter' and a 'VOM meter' are different terms for exactly the same thing -a meter that can be used to measure voltage, current, and resistance. These meters can be either analogue or digital. Analogue instruments are now being priced out of the market by digital meters, due to the manufacturing costs of analogue instruments. Digital meters are more rugged and easier to read than analogue instruments, but not necessarily more accurate.


How is an multimeter connected to take a measure?

Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
