Josh, didn't your meter come with the front and rear rubber bumper guards? Best, |

Best, --- End quote --- Haha, yeah, I had to remove the bumper guards so both meters would fit under that shelf. I'll eventually make a taller shelf with more stuff going on to organize my bench, and the bumpers might go back on the meters. The thing is that I'm tempted to put the SDG2122X on the bench too if I can come up with a reason to need a better AWG than what's on my scope. I was considering setting up a rack, but I dunno if I'll go that route. I kinda like the way the stuff is now. |

I tested a bunch of guitar pickups, I really like this meter. I used Ls-Rd for L and DCR at 100Hz, then switched to Cs at 100kHz. Much simpler workflow than clunking through the DE5000. Here's a couple of them. Pickup 1: DE5000: 4.11H 7.493kΩ 126.98pF TH2830: 4.10479H 7.47774kΩ 143.844pF Pickup 2: DE5000: 3.578H 8.08kΩ 128.59pF TH2830: 3.57755H 8.05381kΩ 128.415pF |

I ordered some generic kelvin clips from ali. I tried one set on the TH2830 and compared them to the TH26011CS. I made an exciter coil to test guitar pickups with an AWG and scope. This is the coil being measured (on the TH2830). TH26011CS: Ls 22.9412μH Rd 117.879mΩ Generic: Ls 24.4134μH Rd 116.482mΩ That's not too bad. So I chopped the cable and converted the TL-22 to kelvin clips for the DE5000. Tested a "tropical fish" film capacitor, 1kHz, 1V. DE5000: Kelvin: 26.2nF 21.1Ω (stable) TL-21: 26.2nF 18.8Ω (unstable) TH2830: TH26011CS: 26.1860nF 22.7711Ω And now the DE5000 can go back to living in the meter drawer. |

When I click on your spreadsheet results in reply #47 I only see a picture of your DE5000. The results from a DMM for the value of an electrolytic is not really comparable to the results from an LCR meter.
