Key specifications

• Measurement type: True RMS
• AC/DC current range: 10mA to 1000A
• Display: Digital LCD
• Measurement category: Standard electrical diagnostics
• Power source: Battery operated

How to use

To perform a measurement, select the appropriate function on the rotary dial based on the parameter you wish to test. Open the clamp jaws by pressing the trigger and enclose a single conductor carrying the current. Ensure the jaws are fully closed for an accurate reading. For voltage or resistance measurements, connect the provided test leads to the designated input terminals and touch the probes to the circuit points. Always ensure the device is set to the correct range before making contact with live circuits to prevent damage to the meter.

What to consider before purchase

• Verify that the current range meets your specific project requirements
• Ensure the device is compatible with the types of conductors you typically work with
• Check if the physical size of the clamp jaws fits your cable diameters
• Confirm that the safety rating aligns with your workplace environment standards

Usage recommendations

Always inspect the test leads for any signs of damage or exposed wiring before each use. Keep the clamp jaws clean and free of debris to ensure they close completely, as any gap can significantly affect the accuracy of your current readings.
