Any recommendations for a quality VOM? I'm tired of cheap junky ones.
It isn't your cheap junky meter.
It is how you are using it.
10A setting you must use the input marked 10A.
On 10A setting you will have a very low current resolution of .1A at a time which will not reveal very low current draws.
Your DVM should have a MA (Milliamp) setting (may look like 1000 (1000 is 1A), 100, 10) which has a higher resolution. That setting will use your normal DVM "Volt/resistance" input lead.
Choose the highest range on the MA setting then switch down..
Have to very careful when using the MA setting as it is to smoke the meter..
Good to know.
Thanks
