How to choose a multimeter
A multimeter is a universal device that combines the functions of an ammeter, voltmeter and ohmmeter. The device can be useful in case of many malfunctions - breakdowns of home appliances, failure of car electronics. The device is used for diagnostics and subsequent repair of radio equipment.
When choosing a multimeter, it is important to pay attention to several basic characteristics.
Functional
Any quality multimeter should measure:
- voltage and current in several ranges;
- alternating and direct current and voltage;
- resistance within several limits (from Ohm to MOhm).
A standard feature for the multimeter is also continuity testing.
Some models allow you to test diodes and transistors, as well as estimate capacitance and inductance. Such multimeters are more expensive, but their scope is wider.
A multimeter is a device that, in its basic version, measures resistance, voltage and current. Important! Although measuring inductance and capacitance is a very useful function in a multimeter, it can be performed with a high error. If you need to set the parameter values accurately, you should use highly specialized instruments.
Error
Any multimeter allows for a certain error when taking measurements. As a rule, its value is 0.025-3%; the lower the value, the more accurate the device.
For domestic purposes, devices with an error of up to 3% are usually quite sufficient. If you need a device for diagnosing and repairing electronics, then it is important to take the best multimeters with an indicator of no more than 1%, and ideally less.
Range
Any multimeter has lower and upper limits of capabilities. For example, if the device does not detect voltage greater than 500 V, then if used on an electrical appliance that is too powerful, it will turn off or burn out. And if you try to measure millivolts with a device not intended for this purpose, it will not provide reliable readings.
Build quality and ergonomics
The actual usability of the multimeter is of great importance. Before buying a device, you need to make sure:
- in the brightness and information content of the display;
- as a mode switch, it should not wobble or move too tightly;
- in order to ensure the convenience and safety of the inlet holes, it is necessary to connect the probes to the tester and check that the contact is reliable and accidental touching of the conductive circuits is excluded.
Before purchasing a tester, you need to carefully examine the device for build quality. You
also need to inspect the probes themselves; they must have strong and flexible wires, sharp electrodes, and fit tightly into special connectors.
Additional functionality
Not all multimeters have additional functions. But it’s very good if the device supports:
- dialing with sound signal;
- checking the gain of transistors, although the results will be inaccurate, a multimeter will help determine that the element is in principle working;
- checking the serviceability of the pn junction.
Advice! If the device is intended to be used in places with difficult access, it is recommended to choose a multimeter tester that is protected from moisture and dust.
What measurement error should be?
Each measurement (for example, alternating and direct current or voltage) has its own error, which must be indicated in the product passport. On average, in household multimeters the error of all measurements “floats” in the range from 0.025 to 5%. For many of the measurements we make for simple tasks, an error of even 5% is not that great. However, it is still better to take a device with minimal errors.
Resanta DT 830B
Let's give an example: the Resanta DT 830B multimeter has a resistance measurement error of only 0.8%, while the more expensive IEK Professional MY61 device has as much as 5%. Of course, the device from IEK has many other useful functions that its cheaper brother does not have, but if the accuracy of resistance measurements is important to you, then it is better to take the DT 830B.
Which multimeter to choose for home and car
Almost any multimeter is suitable for household and automotive use, the main thing is that the tester is, in principle, at hand. In this case, it is quite enough if he is able to:
- measure voltage in batteries and electrical appliances;
- check electrical wiring, light bulbs and fuses;
- measure the leakage current in the car;
- assess the battery charge from the generator.
A tester for a car should cope with basic functions and with continuity of wiring.
If you are going to buy a multimeter for a car, it is desirable that it has a durable case and bright backlight.
Which is the best multimeter for radio amateurs?
To repair radio equipment, it is also necessary to use a tester with advanced functionality. The device must support not only the functions of a voltmeter, ohmmeter and ammeter, but also measure inductance and frequency, capacitance, and also check transistors for functionality.
To work with radio equipment, it is better to choose improved testers that measure capacitance and frequency
Attention! When choosing a multimeter for a radio amateur, you should give preference to units included in the State Register of Measuring Instruments; they demonstrate maximum accuracy.
Which digital multimeter is better to choose?
