Re: CurrentCost - Accuracy?

[Stuart Poulton <stuart.poulton@xxxxxxxxxxxxxx>]

Hi Craig,

A Couple of suggestions.

1 - Ensure that the clamp is completely round the cable, and that the
cable passes through the centre at right angles to the main body of the
clamp.

2 - CC can only actually measure the current, not the power usage. The
power used assumes a fixed voltage of (I'd guess) 230v, and resistive
loads (your typical no banned light bulb).

Regards

Stuart
