I would also recommend one that will read DC Amps, up to 10 A. That is useful for testing for things draining power, and how much power items are using. I bought a super cheap digital one from harbor freight tools a couple years ago. It has up to 10A, and all the other usual ranges. It also has a built in battery tester for 9v and 1.5v batts that puts some load on them while testing. And a transistor tester, which I will never use. I was going to hack it open and use it as the basis of a comprehensive electrical system monitoring display for the van. I was going to use a selector switch so that I could check voltage on both batteries, and current going into or out of the aux batt, and maybe output voltage from the inverter. Haven't gotten to that yet, but the stupid little meter is still working. I have really zapped the Ammeter section of it a couple times when I forgot it was in that setting and went to measure battery voltage. It still keeps working. Edward |
