Gordon Three - WoW haha.. I would have never caught that...
I will using one to measure the DC LOAD from the trailer as well as how much DC CURRENT is being demanded by battery bank when being charged...
I have the same Hall Effect +/- 70A DC Current meter that Don has and it has spoiled me big time. Both Don and I got these back in 2008 when they was being sold by a company called SURE ELECTRONICS from CHINA. I only got one and Don got two haha... Right after we bought them they sold out and became very expensive (Around $800) from another company called FCB ELECTRONICS... I doubt if FCB sold many of those at that price...
Mine has worked flawlessly since 2008... I need two more plus a spare now haha
