Perguntas frequentes

1. What is a digital multimeter used for?

A multímetro digital is used to measure voltage (AC/DC), current, resistance, and frequency, helping electricians and technicians diagnose electrical circuits, troubleshoot faults, and verify system performance. It is widely used in electrical maintenance, HVAC systems, industrial testing, and electronics repair.

2. What makes the HK48D different from the HK36A+?

O HK48D digital multimeter includes AC current measurement and frequency testing, while the HK36A+ focuses on basic electrical measurements.
Additionally, the HK48D features auto-ranging, making it more efficient for users who need fast and versatile electrical diagnostics.

3. Is the HK48D a True RMS multimeter?

Yes. The HK48D is a Multímetro de valor eficaz verdadeiro (True RMS), which provides accurate readings when measuring non-linear loads such as variable frequency drives (VFDs), HVAC systems, and modern electronic equipment.

4. Does the HK48D measure AC current?

Yes. The HK48D supports AC current measurement up to 10A, making it suitable for basic electrical testing, appliance diagnostics, and maintenance work.

5. Does the HK48D support frequency measurement?

Yes. This frequency multimeter can measure up to 20kHz, which is useful for testing signal frequency, power systems, and electronic circuits.

6. Is the HK48D auto-ranging or manual range?

The HK48D is an auto-ranging multimeter, allowing it to automatically select the correct measurement range. This improves speed, convenience, and ease of use, especially for field technicians.

7. Does the HK48D include NCV (non-contact voltage detection)?

No. The HK48D does not include Detecção de NCV.
If non-contact voltage testing or live wire detection is required, the HK36A+ may be a better choice.

8. What safety rating does the HK48D have?

The HK48D is rated CAT III 600 V, making it suitable for distribution-level electrical testing, including panels, circuits, and building wiring systems.

9. Is CAT III 600V enough for electricians?

Sim. A Multímetro CAT III 600 V is sufficient for most trabalhos elétricos em edifícios comerciais e residenciais, including distribution panels, wiring systems, and equipment testing.
For higher-risk environments such as utility or outdoor power lines, a Multímetro CAT IV may be required.
