John Warren Posted January 17, 2022 Share Posted January 17, 2022 I had one and managed to score a second. They express voltage on a log scale allowing 5 decades to be captured on the swing of the needle pointer. Useful to measure voltage across a load resistor for amplifiers under test. The right unit is the first issue, 1968, all gold traces. The left unit is the last year of manufacture, 1976, Pb-Sn traces. That unit also needs a knob, which I found on-line and ordered! Measures both VAC and VDC from 1mV to 100V and dB equivalents. 2 1 Quote Link to comment Share on other sites More sharing options...

I assume you can also measure voltage across crossover outputs? I'm going to build a new crossover for my Heresy's, but was curious what the current E2 crossover was doing. I'm using REW to do the sweep/measure, and this is what I got. Would be nice to have one of those devices to verify my results.

tigerwoodKhorns Posted January 17, 2022 Share Posted January 17, 2022 John, Slightly off topic but something that I have been thinking about in the last few days. I want to get a better VOM meter. What do you recommend? I want one for a 'clean' toolbox that I use for electronics, crossover building, etc. I am a hobbyist, so nothing too fancy (expensive). I saw some Youtube videos and they guy had a Ryobli TEC4 that looked nice. Don't know budget. I have a few throw away free meters from Harbor Freight and a Velleman dvm850bl meter (now around $30 - about $60 when I bought it) for working in dirt places, outside, landscaping etc. But at a short it shows 0.5 ohm and you turn a dial instead of an on off switch, so not the best meter. What do you recommend? I can move to a different thread if you like. Quote Link to comment Share on other sites More sharing options...
