Amprobe CR50A Capacitance and Resistance Tester

It is only the capacitance section that I was interested in when I bought it, and it is the only part that I In order to align the leads with the zero adjust knob to cancel out the capacitance of the leads, I put the unit into nanofarad range after installing the battery. The initial setup was straightforward. New batteries always lead to improved accuracy, so I would install a new 9V battery. I saw those speed slits when I looked closer! The feature I like best about this meter is It can be removed from the leads and has those cool little slits in the front, allowing you to test dozens of capacitors in under a minute. Capacitors can be quickly tested with this meter without having to deal with leads, making it a fantastic tool for checking a lot of new capacitors. So as I mentioned, I immediately began testing dozens of electrolytic capacitors from my inventory. I found the meter to be extremely rock solid, and it was repeatable for all We used this meter to test some known capacitors that we've measured in our lab using an Agilent rig in the past, and I was quite satisfied with its accuracy. The CR50A meter immediately pointed out which manufacturers of capacitors in my inventory are accurate about the capacitance stated on the caps. It pointed out three premium Japanese capacitor brands that are very reliable when it comes to getting the capacitance stated on the capacitors. The Rubycon Group (Chemi- It comprises Nichicon, Con, and Nichicon) The Panasonic capacitor tolerances were disappointing, even though they were well within the permitted range Though they still maintain a high level of reliability, I think they should try to get their stated values down to less than 1%, like these three other premium brands have done. Instead of the 6% off that I measured, I think they should strive for less than 1%. You might want to stay away from the Chinese capacitors I checked since they are wildly inaccurate. It would only be possible to improve the system if there were an automatic resolution mechanism For such a feature, you'll have to invest $500 or more in a capacitance tester. I guess that is asking too much on a $100 meter.

The book is great. I'm glad I picked it up. *Amazed me with our early arrival. Worked fine for me. The book is great! I'm glad.

This program does exactly what it claims it will do, and it.

This is a very good piece of work.

It is not like that cheap garbage at Harbor Freight. The one I have now is blown up, so I'll have to buy another.

The results were excellent in terms of accuracy and repeatability A measure's ability to be determined. It's a great deal for the money you're spending. As a part of my home toolkit, I love Amprobe. The Agilent meter is more precise, but it doesn't quite measure the same as it. Furthermore, once you own one, you don't have to sell them your unborn child as well. The tool is very useful and if you are on the lookout for a cost-effective capacitance / resistance meter, this is a good choice.

As advertised, the product met expectations. Quite good value for the money.
