A little disappointed in my Fluke 81438 multimeter. I use it mostly for reading VAC or VDC and HZ hardly ever for any ohm readings if I want of think I need to know the true resistance since it has no zeroing adjustment. I had removed the batteries from both my Simson 260 multimeters since I rarely need to use them I don't want the batteries available today to develop a leak in them.
I checked my LaBlond 17inch lathe today with the flake, "sorry" the Fluke, I hadn't used the lathe in about a week so the first test reading came out to be .8 ohms. but when I put the ends of both leads together instead of getting a reading of o,oo I had a reading of 0.2 ohms Huh? so I removed the red lead and touched the black lead to the red lead socket , o.1ohms, same for the red lead when I touched it. Checked from the chuck to the bed again and the reading was 0.8 ohms. SO I'm going to call that one 0.6 phms allowing for the 0.2 of the leads. I did a 1/4 rotation same reading half rotation no change full rotation still no change.
Since I never start my lathe after it has been sitting unused for a full day or more I filled the oil cups the turned it on for a few seconds the took readings again 8.2ohms I decided to switch it on at a low RPM and hold the probe to the outer edge of the chuck while it was turning and the bed. Nothing no continuity reading at all OK at the highest reading nothing. wondering about whether there was a possibility of the chuck generating voltage I set to DCv at low RPM touching the chuck and the bed nothing. High RPM . 0.001VDC I will get some new batteries for my Simson meters the next time I think about it and check with them
