In the auction description is the upper capacitance value a mistake? It looks like there is a 0.08 uF cap, but the description says the capacitance range is 100 pF to 0.06 uF. So should probably be 0.17 uF? Thanks! You are correct; that is an error. As you can see in picture http://cgi.ebay.com/ws/eBayISAPI.dll...ayphotohosting the on/off switches chose between the following values: 0.08uF 0.04uF 0.02uF 0.01uF = Top decade, adjustable from 0uf to 0.15uF in 0.01uF steps 0.008uF 0.004uF 0.002uF 0.001uF = Middle decade, adjustable from 0uf to 0.015uF in 0.001uF steps 800pF 400pF 200pF 100pF = Bottom decade, adjustable from 0pf to 1500pF in 100pF steps So the total is adjustable from 0uF to 0.01665uF in 100pF steps. The capacitors are +/- 7.5%, so that's the maximum difference from setting error. You can, of course, tweak that up and down until you are within 7.5pF of your desired value, subject to how accurate your capacitance meter is. I will correct the error on all future listings. I would like to send you one for free for correcting my error. Please email me with the address you want it sent to. If you have bid on the auction, please let me know and I will cancel your bid (unless, of course, you want two of them!) My email address is engineer [at] guymacon [dot] com. Thanks again for finding the error. |
