content: So, I asked a while ago about a keithley 2k vs some other meters. As a result of that post I decided to get myself a keithley 2000. When I was looking on ebay, I spotted a seller offering a 2015 for just a fraction more than any of the 2000s that were offered (at least the ones that looked like they were in ok condition), and the seller was in germany, which meant much cheaper shipping. I was now wondering if there was any reason I should still go for the 2000 instead of the 2015. From what I can tell, the 2015 is just a 2000 with some extra functionality slapped on. Is this really the case, or does it have different measurement capabilities? I already looked through the manual and couldn't immediately see something.

content: Yes, the 2015 is a 2000 with the additional THD capabilities. I've got one, and I didn't find any drawbacks.

content: K2000 has somewhat better specs for 10 MOhm and 100 MOhm ranges:±(ppm of reading + ppm of range), 1 year10 MOhm: 400 + 10100 MOhm: 1500 + 30vs. K2015:±(ppm of reading + ppm of range), 1 year10 MOhm: 600 + 10100 MOhm: 2200 + 30This is the only difference in specs I've noticed.Btw. Keithley (Tektronix) released new version of K2015 datasheet where they warn about availability of K2015 in EU:This product is not updated to comply with the RoHS2 Directive 2011/65/EU and will not be shipped to the EU. Customers may be able to purchase products from inventory that were placed on the EU market prior to July 22, 2017 until supplies are depleted.https://www.tek.com/datasheet/audio-analyzing-digital-multimeters/models-2015-and-2015-p-6-1-2-digit-thd-multimeters-and

content: Quote from: saturnin on November 26, 2017, 01:06:05 pmThe 10 M? and 100 M? ranges are not that important to me, so I think I'll take the THD functionality (and then mainly the low-frequency high-linearity signal generator) over the slightly worse range.Regarding the RoHS stuff: The unit I wish to get it second hand and already within the EU and thus does not fall under that law.Thanks for pointing it out though.

content: Well, I ended up running into an auction for a Keithley 2000. In the end I went for that, since the end cost was about 1/4 lower, and I doubt I was gonna use the 2015's THD functionality all that much. Better put that saved money into the testleads.Thanks for the help anyways, guys!
