Pinça amperimétrica Wiha 45219 CAT IV 1000V 400A AC DC tensão

The Wiha 45219 clamp meter measures AC and DC currents up to 400 A and is rated to CAT IV 1000 V for safe work on low-voltage sources. It combines a clamp bracket for current measurements without opening circuits, remote single-hand testing, voltage measurement in AC and DC ranges, and tests for resistance, frequency, capacitance, continuity and diodes. A large backlit LCD with data-hold makes readings easy to see; LPF and True-RMS functions improve measurement fidelity. The tool is powered by AAA batteries and includes an integrated flashlight for use in poorly lit environments.

Advantages

The clamp meter enables current measurement on live conductors without interrupting circuits and supports multiple test functions relevant to electricians in one device. Its remote single-hand operation and large illuminated display simplify handling and reading of results. LPF and True-RMS measurement modes increase process reliability by providing stable, interference-reduced values, while the integrated flashlight improves visibility during work.

Suitable for

• Measuring AC and DC currents up to 400 A
• Voltage measurements in AC and DC systems up to CAT IV 1000 V
• Resistance, frequency and capacitance testing
• Continuity and diode checks
• On-site electrical work in poorly lit locations

How to use

Place the clamp around a single conductor to measure current without breaking the circuit; use the remote single-hand control for easier operation. Select the required measurement function (AC/DC voltage, resistance, frequency, capacitance, continuity or diode) on the meter, read values on the backlit LCD and use data-hold if needed to freeze the reading. For continuity checks listen for the audible signal. Use the flashlight to illuminate the workspace when necessary and replace AAA batteries when display or functions become weak.

Recommendations

Before use, verify the meter’s condition and battery level. Follow safety procedures for working on live installations and ensure the clamp surrounds only one conductor at a time. Do not exceed the specified CAT IV 1000 V and 400 A ratings. Store the instrument dry and avoid mechanical shocks to maintain measurement accuracy.
