Have a look on Maplin website, item L61AQ is a plug in power meter that shows voltage, amps, watts of appliance plugged in.

I have always used a clamp meter, to check when heater/elements are energised. Also if motors are drawing to much current.
Just check heater for continuity as usual then place clamp over one wire to heater and read amps, you can then tell when heater switches on/off without need to use probes on multimeter to read voltage. Multimeter only tells you if voltage is at the heater not if the it is working.

So having checked heater (or any other component) for continuity and then attached clamp meter what would you be looking for specifically? (apart from it turning on and off)

staying with the element example, I take it you would ascertain the wattage off the plate if available, then from that calculate what amps a good element would draw. . .?

So if the element was rated at 2300w with a 240v supply, using our handy calculator (thanks spimps and kwatt) it should pull 9.5amps

Hi Jim

No but that was going to be plan A, to arrange for calibration day, but thought after not many would take up the offer:!:

So went for plan B, they will give you details on cost etc and I am sure if you did bring it along they could take it away and then post back within a couple of days 😀

Maybe we can see what the interest is on calibration and if the take up is good maybe we can arrange it for another time.

Yep Neil 9.5 or 9.6 depends whether you decide to round up or down, with Ohms law as long as you know 2 of the values you can quickly work out the third.

Nice job Ken, that looks an Excellent Ohms law calculator.

Working near Maplins this morning at Cheshire Oaks so popped in and got a power meter £6.99 special offer and a clamp meter £9.99

Had an interesting day playing with new toys and observing amps etc and applying ohms law.

i suppose after a short while you come to know what readings to expect especially on common machines.

What are the power meters like Neil? every time i’ve been into our local Maplin they’ve been out of stock.

As for what readings to expect, I bet before long it becomes second nature to you 🙂

Just plug it in and an instant visual of whats going on in the appliance.

Plugged into my own washing machine to discover that it is, according to ohms law fitted with a 2.8kw heater that was energised for only about 10 minutes to get the machine up to 60 degrees, which just shows the value of the old hot and cold fill system.

Both bits of kit fit easily in my tool box as i can now do without my old multimeter.

Cheers mate, i’m going to Cardiff tomorrow & will go into Maplin store there to get 1.
