Multimeter Wiha 45218 — digital multimeter, up to 600 V AC, CAT IV

The Wiha 45218 digital multimeter is a handheld measuring instrument intended for voltage, current and basic electrical diagnostics. With a safety rating CAT IV and measurement capability up to 600 V AC, the meter is designed for use on mains installations and secondary distribution points. Its compact housing, clear numeric display and straightforward controls support routine on-site troubleshooting and verification tasks for electricians and technicians.

Advantages

The instrument offers a clear, easy-to-read display and protective casing that supports safe operation in environments with high transient voltages. The CAT IV safety rating and 600 V AC measurement limit provide appropriate protection and capability for measurements near service entrances and distribution equipment. Lightweight and ergonomic design helps reduce fatigue during extended field use while robust construction increases reliability in workshop and site conditions.

Key specifications

• Measurement range: AC voltage up to 600 V
• Safety rating: CAT IV for mains-level measurements
• Display: digital numeric readout for voltage/current values
• Form factor: handheld, compact housing with protective casing
• Intended measurements: voltage, current and basic continuity/diagnostics

How to use

Before use, visually inspect the meter and test leads for damage and ensure the instrument is set to the correct measurement function and range for the task. Connect the test leads to the appropriate terminals and observe polarity when measuring DC. For AC voltage measurements up to 600 V, select the AC function and place the probes across the measured conductors or at the test points in the installation. Read values from the digital display and remove probes when finished. Follow standard electrical safety procedures, de-energize circuits when possible and use personal protective equipment as required.

Recommendations

Use the multimeter for routine verification and fault-finding on mains and distribution equipment within its rated voltage and safety class; avoid exposing the instrument to voltages or transient conditions beyond its specified limits and store it in a dry, dust-free environment when not in use.
