Not sure if I agree... the price difference between a multimeter that will not measure AC current, and one that will measure 10AC is about 100% - one is double the other. Alternatively I could get myself a clamp on type to use for the current measurements. I'm offered a MT87 at a really cheap...
Could anyone suggest a suitable meter that will? Looking for basic AC and DC Voltage and Current measurement, with max of 600V / 10A. Any other features a bonus. Obviously the $1,000 dollar version does, but I'm on a budget.
A real simple question... I'm trying to measure an AC current in the region of 8A. My multimeter is a Major-Tech MT845 - quite old, digital. It has DCV, ACV, DCA, Ohms settings on the dial but no ACA (AC Amps?). I gather I cannot use it then for my purpose?
I'm looking for some info around the distance constraints between sensor and micro-controller. If I had the sensor component (a toroid type current transformer) located about 20m away from the "reading" component, would it work? My design at present aims to provide 1.1v on the sensor output, and...
Hells teeth, me too :)
I've got a question on winding a toroidal coil for the sensor element... A toroid of approx ext 35mm diam, with 100 turns of enamelled wire.... how important is it to have the turns wound neatly, and tightly against each other? Does it matter if they are overlapping each...
? I don't see anything.....?!?!?

Ahhh, sorry... took a while for the attachment to appear. Apologies.
I'm looking for a DIY kit to build a data logger than records kWh consumption... not having much luck. I know the devices are available commercially, but I'm interested in putting one together myself. Any pointers?
Thanks.
