Skrutkovač na testovanie napätia Wiha 45217 červená žltá

The Wiha 45217 Voltage Tester Screwdriver is a compact tool for checking voltage, continuity and basic electrical parameters in building installations and on low-voltage sources. It supports voltage measurement from 0.5 V up to 1,000 V AC and up to 1,500 V DC, and combines a screwdriver form factor with multiple test functions for everyday electrical work.

Advantages

The tester provides a wide measurement range and multiple functions in a single handheld tool, including continuity testing, optical rotational field detection, single-pole testing, automatic polarity detection, resistance and frequency measurements. A large backlit LCD and LED indicators make results easy to read, while an audible signal confirms continuity. The integrated spacer enables one-handed testing of sockets and a built-in flashlight improves visibility in poorly lit areas. The tester meets safety categories CAT III up to 1000 V and CAT IV up to 600 V for safe use on building installations and low-voltage sources.

Suitable for

• Quick voltage checks on sockets, switches and electrical circuits
• Continuity testing of cables and connections
• Rotational field detection for motors and three-phase systems
• Resistance and frequency measurements for basic troubleshooting
• Functional testing of residual-current (FI) protective devices

How to use

Use the Wiha voltage tester screwdriver by placing the tip on the conductor or contact to be checked while holding the insulated handle. Read the measured value on the backlit LCD or LED indicators and listen for the continuity signal when performing continuity checks. For functional testing of an FI protective switch, press both buttons on the test-tip handles simultaneously to connect the internal load. Use the integrated spacer to steady the tester and enable single-handed insertion into sockets. Follow standard safety procedures and ensure zero voltage where required before performing work.

Recommendations

Check the tester visually before use for damage to insulation or probes. Always confirm zero voltage on circuits before starting electrical work. Use appropriate personal protective equipment and follow local safety regulations when testing live circuits.
