hi john, if you're only going to test a meter then u probably don't need a 300watt inverter (stepped sine wave output) or even a small UPS like u use for your computer. But a small stable audio oscillator with a known output voltage, like a dick smith kit, and then use a small power transformer to step the voltage up to 240. so, if the audio ascillator has an output of 5v @ 50hz, then use a 240v~5v trnasformer to step up to 240v at low current. it's rough, small and cheap - i assume u don't need a calibrated unit.
