I was checking the resistance through my coil, and a couple of spare coils, a few days ago, and got a nice comfortable 4.4-4.6 ohms on the various coils. It then occurred to me that I should check my multimeter to see what the baseline resistance (lead tip to lead tip on low, 200 ohm, scale) was. I got about 1 ohm. I have several low-medium priced multimeters ($35-50 range) and found this was true with all of them.
Should I subtract this from the measured result, like the tare on a scale? If so, my coil resistance is a little low and I'll need to add a resistor.
The alternative explanation is that the lead wires on the meter do have some resistance, but it's too low for the ohmeter to measure accurately and it's just spitting out a "1".
