I want to preface this by I am a hobby electronics guy with some experience from reading The Art of Electronics. I know how to use a multimeter but I am very confused at what I am seeing.
I am using a marginally more expensive Circuit Specialists multimeter and testing the resistance across a set of fuel injectors I am working on. My procedure to test is as follows:
- Set multimeter to Ohms (200)
- Measure resistance across the male side plugs
I was looking for a reference range of 10-14 ohms and I got 15.3 ohms. Concerning. So out of curiosity I measured again:
- Set the mulimeter to Kilohms (2k ohms)
- Measure the resistance across the male side plugs.
However this time I got 0.012! So 12 ohms, right in the middle of the range.
It may be as simple as my multimeter just isn't very high quality but I was hoping there was a better explanation. Having one measurement outside spec, and one inside spec really bothers me.
My multimeter model is #MT-5211
