What Are Voltmeters and Testers?

Voltmeters and testers are devices designed to measure electrical voltage, current, resistance, and other electrical parameters. They are indispensable for diagnosing faults, checking battery condition, alternator operation, or installing new audio equipment. In our range, you will find both simple automotive voltmeters with different colored backlights and specialized breathalyzers for determining sobriety.

How to Choose the Right Voltmeter or Tester?

When choosing a voltmeter or tester, it is important to consider its purpose and functionality. If you are looking for a device to monitor your car's electrical system, a simple automotive voltmeter will suffice. For more complex tasks, such as installing an audio system, you may need more precise instruments, such as amplifier installation accessories, which will help ensure proper wiring and system operation. Also, if sobriety testing is required, we offer reliable breathalyzers. Don't forget to check out other tools and installation accessories that will make your work easier.

Most Popular Manufacturers and Types

In our collection, you will find voltmeters and testers from various manufacturers. Although some products are from discontinued series, we still offer reliable LaviLine, Laverna, and Audison Connection products. The assortment is dominated by accessories, but you will also find specialized tools. For example, the LADB02V distribution block with voltmeter is perfect for those looking for integrated solutions. Breathalyzers, such as Alcodetector S60 or Dräger Alcotest 3000, ensure reliable results.

Frequently Asked Questions (FAQ)

Ar reikia voltmetro automobilio garso sistemos diagnostikai?

Labai naudinga. Multimetras (15–30 €) leidžia matuoti akumuliatoriaus įtampą (turi būti 12.6V ramybėje, 13.8–14.4V variklis veikia), srovę, varžą. Greitai randama problema – įtampos kritimas, blogas įžeminimas, perdegęs saugiklis.

Ką matuoti audio sistemoje?

Pagrindiniai: maitinimo įtampa prie stiprintuvo (turi būti panaši į akumuliatoriaus), remote-signalas (turi būti 12V įjungus magnetolą), garsiakalbio varža (turi atitikti deklaruotą 2Ω/4Ω), RCA įtampa (turi būti 0.5–4V audio signalui).

Ar reikia oscilloscope'o profesionalaus tuning'ui?

Tik profesionaliam SQ tuning'ui – oscilloscope rodo signalo formą, leidžia matyti klipsą, fazes neatitiktis. REW (Room EQ Wizard) su matavimo mikrofonu – populiaresnė alternatyva car audio entuziastams (be brangaus oscilloscope).

Kam reikalingas borto voltmetras automobilyje?

Borto voltmetras (pvz., LaviLine su spalvotu apšvietimu) nuolat rodo akumuliatoriaus ir generatoriaus įtampą, todėl iškart pastebėsite, jei ji krenta arba kraunasi prastai. Tai ypač naudinga galingoms garso sistemoms, kurios stipriai apkrauna elektros tinklą. Dažniausiai montuojamas į žiebtuvėlio (12V) lizdą arba prie prietaisų skydelio.

Kas yra kontrolinė lemputė (testeris) ir kaip ja naudotis?

Kontrolinė lemputė 6–24V (pvz. LaviLine) – tai paprastas zondas su smeigtuku ir įžeminimo gnybtu, kuris užsidega aptikęs įtampą laide. Ja greitai patikrinsite, ar prie remote, maitinimo ar apšvietimo laido yra srovė, neturint multimetro. Tikslioms įtampos reikšmėms vis tiek geriau tinka voltmetras.
