Watts Up Meter
I'd bought the Watts up meter a while ago and it is a cheap and simple amp hour meter. It is normally used for measuring power consumption on radio controlled vehicles and can handle upto 60 amps at 12 volts. It can also measure Amp hours, Voltage, Minimum Voltage, Watts, Amps, Maximum Watts and it is reset when the power is removed to it. Unlike more expensive amp hour meters it only meaures power in or power out and not both. It will still be useful for me for measuring my power consumption though as I'm not sure how much power my compressor fridge and eberspacher are taking out of the Leisure batteries.
Since I'd wired all the items which run from the leisures through an earth ring this made it really quick and easy to divert the earth through the watts up meter supply it a positive feed through the fuse box and get it working. I mounted the meter on one of the arches at the back of the van as I won't need it look at it very often. I also add a switch to turn it off and an extra switch for the water pump which I will be adding in a day or so.
Once it was fitted and I turned on a some lights it seems to do what it says on the tin and told me how many watts I was using.
