The easy way to measure high AC currents is to use a clamp meter but these are generally quite expensive and cost several hundred dollars at a minimum. Add-on clampmeter adaptors can work well but ...

Fluke once again has solar power engineers in mind with a pair of instruments, both true-RMS, CAT III and rated to 1,500V: the 283 FC digital multimeter and the a283 FC wireless ac and dc current ...

If your goal is to save on electricity, you must first measure the ac current flowing through your appliances. The formula for power is the product of the ac line voltage and the measured current.

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...
