Its lightweight and compact form factor allows for easy portability, making it an essential addition to any technician's toolkit.

Suitable for

• Troubleshooting residential and commercial electrical systems
• Measuring AC current in cables and wires
• Checking voltage levels in household appliances
• Performing continuity and diode tests
• Maintenance tasks in HVAC and refrigeration systems

When it may not be suitable

This device is not intended for measuring high-current industrial applications exceeding 400A. Additionally, it does not support DC current measurement, so it is not suitable for automotive battery charging diagnostics or other DC-specific current testing tasks.

Key specifications

• AC Current measurement up to 400A
• AC/DC Voltage measurement up to 600V
• Resistance measurement up to 40MΩ
• Capacitance measurement up to 100µF
• Frequency range from 10Hz to 1MHz
• 30 mm jaw opening
• CAT III 600V safety rating
• 4000-count display resolution

How to use

To begin using the clamp meter, insert the provided batteries into the compartment on the back of the device. Select the desired measurement function using the rotary dial. For current measurements, press the trigger to open the jaws, clamp them around a single conductor, and ensure the jaws are fully closed. For voltage or resistance measurements, connect the test leads to the appropriate input terminals and touch the probes to the circuit points. Use the Data Hold button to freeze the reading on the screen if necessary, and utilize the Relative mode for offset measurements.

What to consider before purchase

• Verify that the 400A current limit meets your specific project requirements.
• Ensure that you do not require DC current measurement capabilities.
• Confirm that the 30 mm jaw opening is sufficient for the diameter of the cables you intend to test.
• Check if the CAT III 600V safety rating is appropriate for your working environment.

Usage recommendations: Always inspect the test leads for any signs of damage before use. Ensure the device is set to the correct measurement mode before making contact with live circuits to prevent damage to the meter. Store the device in a dry, cool place and remove the batteries if the meter will not be used for an extended period.
