Description

The Joulemeter/Wattmeter is light, compact,
and designed for class demonstration or student
use. The unit can measure energy taken up by a
load, either by AC power or DC power, and from
1J to 999,999J or 1mJ to 999,999mJ and can also
measure power level of 200mW to 200W. One
pair of 4mm sockets is also provided to indicate
the instantaneous power. Depending on mW / mJ
or W / J range, 1V full scale deflection represents
100mW or 100W respectively.
