About This Product
Measuring electrical energy directly saves students from multiplying voltage, current and time by hand, and lets them compare that calculation with the meter reading. The unit is light and compact, designed for class demonstration or student use, and its pair of 4mm sockets indicates the instantaneous power alongside the 6-digit energy and power indication.
Frequently Asked Questions
Can it measure AC and DC loads?
Yes. It measures the energy taken by a load on either AC or DC, within an input of 0 to 15V AC or 0 to 21V DC and a maximum current of 10A.
What are the 4mm sockets for?
They indicate the instantaneous power: 1V full-scale deflection represents 100mW or 100W, depending on the range selected.
