Hello,

I wish to measure the power consumption (real power) of an offline (90-265VAC) guitar amplifier (330W max power) over the following intervals:-

1 second
15 seconds
30 seconds
1 minute
5 minutes

Which of the following 2 meters can do this?


HAMEG (£500)
HAMEG|HM8115-2 EU|POWER METER, 8KW | Farnell United Kingdom

MOELLER (£50)
MOELLER|EFERGY E2-METER|METER, ENERGY, WIRELESS | Farnell United Kingdom


The smps that supplies the guitar amplifier is not power factor corrected, so mains input current harmonics will be large.
