What is this clamp meter used for?
This clamp meter measures AC and DC leakage current from 0mA to 60A, making it ideal for troubleshooting ground faults, monitoring leakage current in electrical systems, checking residual current devices (RCDs), and inspecting appliances and power lines for unwanted current leakage.
What is leakage current and why should I measure it?
Leakage current is the small amount of current that escapes from an intended circuit to ground or other paths. Excessive leakage can cause nuisance tripping of breakers, electric shock hazards, or equipment damage. Regular measurement helps ensure electrical safety and compliance.
Can it measure both AC and DC current?
Yes. Unlike standard clamp meters that only handle AC, this meter measures both AC and DC leakage current with a range of 0mA to 60A.
What is the maximum current it can measure?
The meter measures up to 60A of leakage current.
What does Auto Range mean?
The meter automatically selects the appropriate measurement range for the current being detected, so you don’t need to manually switch ranges — just clamp and read.
What is the sampling rate?
The meter samples at a high rate (per specification) to capture fast-changing signals and display stable, accurate readings on screen.
How do I zero the meter before measuring?
Use the Zero Adjustment function. Close the clamp jaws around no conductor (or press the Zero button as instructed in the manual) to null out any residual reading, ensuring accurate small-current measurements.
What is the Data Hold function?
Data Hold freezes the current reading on the display, allowing you to safely view the measurement even in awkward positions or hard-to-see areas.
How much data can the meter store?
The meter can store up to 99 sets of measurement data for later review and comparison.
Can it measure line voltage?
Yes, the meter features Line Voltage detection/indication to confirm that a circuit is live before or during measurement.
Does the meter turn off automatically?
Yes. The Auto Power Off feature conserves battery life by shutting the meter down after a period of inactivity.
How do I know when the battery is low?
The Low Battery Indication alerts you on the display when it’s time to replace the battery.
What maintenance does the meter require?
Keep the clamp jaws clean and free of debris, store the meter in a dry place, replace the battery promptly when the low-battery indicator appears, and recalibrate periodically per manufacturer recommendations.
Is it safe to measure live circuits?
Yes — this meter is designed for non-contact measurement of current through insulated conductors. However, always follow standard electrical safety practices, use appropriate PPE, and never exceed the rated measurement range.
Is this meter suitable for RCD/GFCI troubleshooting?
Yes. Measuring leakage current is one of the primary methods for diagnosing why an RCD or GFCI trips unexpectedly.
