FAQs

A: Standard multimeters measure large, continuous electrical currents. Unfortunately, they cannot detect tiny stray currents hiding inside appliance grounds. However, this high-sensitivity clamp meter reads incredibly small leakage faults accurately. Therefore, you can pinpoint exactly why your GFCI breaker keeps tripping securely.

A: Yes, you absolutely can. Household appliances with older motors frequently develop internal insulation damage over time. Specifically, you just clamp this device around the grounding wire directly. Consequently, it reveals if dangerous current is leaking into the appliance casing instantly.

A: Electrical leaks are often intermittent and extremely fast. Consequently, staring at a flashing screen is totally useless. Fortunately, the Peak Hold mode solves this easily. Specifically, it freezes the absolute highest current spike on the screen automatically. Thus, you never miss crucial diagnostic data.

A: Exporting your saved data is incredibly straightforward. First, install the included PC software using the provided CD. Next, connect the meter to your computer using the RS-232 cable. Ultimately, you can download all 99 sets of measurements for professional graphing and printing quickly.
