Voltage and continuity tester Wiha 45216 12–1000 V AC, handheld tester for AC voltage and continuity

The Wiha 45216 handheld voltage and continuity tester measures AC voltages from 12 to 1000 V and verifies circuit continuity. Designed for electricians and technicians, this compact tester detects the presence of voltage and confirms whether conductors are intact, simplifying basic fault finding and safety checks on electrical installations. Its handheld form factor makes it suitable for both field and workshop environments where quick verification of live circuits and continuity is required.

Advantages

The tester provides a wide AC voltage measurement range, enabling use across low-voltage and high-voltage applications within the specified span. Its compact, handheld design allows convenient one-handed operation and access in confined spaces. The instrument offers clear indication of voltage presence and continuity, helping to reduce diagnostic time. Built with durable materials suitable for regular use, it is intended to support routine electrical checks and basic troubleshooting tasks.

Suitable for

• Quick verification of presence of AC voltage on outlets, switches and junctions
• Continuity checks on conductors, fuses and simple wiring runs
• On-site troubleshooting and preliminary safety checks before maintenance
• Use in workshops for testing components and assemblies

Key specifications

• Measured quantity: AC voltage and electrical continuity
• AC voltage range: 12–1000 V
• Form factor: handheld probe-style tester
• Operation: single-handed use with probe contacts
• Intended environments: field and workshop use

How to use

Before use, visually inspect the tester for damage and ensure probes and insulation are intact. Connect or position the probe tip to the conductor or contact under test while observing appropriate safety procedures for live circuits. For voltage detection, place the probe on the energized point and observe the tester's indication for presence of AC voltage within the specified range. For continuity checks, isolate the circuit from power, then place probes across the conductor or component to verify a continuous path. Follow local electrical safety rules and, when required, de-energize circuits before performing continuity tests.

Recommendations

Use appropriate personal protective equipment when testing live circuits. Verify the condition of probe insulation and replace the tester if any damage is found. Do not exceed the stated measurement range and follow national safety standards and procedures for electrical testing.
