| Does anyone here use the Peak Lcr45? Max Inductance? |

The only reason im leaning tword the lcr45 is becuase it will give you an imedance reading. I can not find a meter under 200 bucks that does that. Is there an easy way to calculate Z using the info given on most any handheld meter? I just noticed the lcr45 doesnt have any frequency options under 15khz so thats now a no go. |

Among the "prominent" ones are the DE5000 or ET44xx from East Tester, but also the ST42 measuring tweezers. --- Quote --- Is there an easy way to calculate Z using the info given on most any handheld meter? --- End quote --- This requires the exact measurement frequency and then conversion (e.g. XL= 2*pi*f*L) And the RDC value for the real component of the impedance. |

Well i figured out the meter i intend to buy after a lot of looking! An east tester et42, it does bias voltage, and calculates Z. For 200ish it seems like the most feature packed meter you can get! I dont understand why Z is omitted from most of these meters, its not like Z requires any hardware the de5000 doesnt have, its much more helpful than esr in my opinion. I mean the de5000 apparently does calculate Z but its only displayed in the desktop app that has a broken link and requires an overpriced and at this point rare cable. The ir cable for my fluke 289 costs less lol. At some point i aspire to build a desktop impeadence analyzer/lcr that will measure a few mhz at higher voltages, i even ordered all the math books i need to help catch me up but for now i just need something to fill in the info i cant get from bode plotting. In the world of great dds chips and cheap fpga/200mhz micros i cant figure out why there isnt anything like the Bode FRA for 500 bucks. |

I know that there usually tested at 100khz or whatever but what is the standard voltage used? I really wish there was something like the Bode frequency analyzer at a reasonable price. Once you get to RF and everything is 50ohm and you can use a VNA measuring this stuff is so much easier. I will probably never need to wrap or use an inductor in a circut using 2v or less. Lets say im working on a 50v 500khz boost converter and i need to wrap a 10microHenery as part of the circuit, is there any way to test my inductor without breaking the bank. At this point i feel like there are a lot of situations where you just pick a core material use a winding calculator and call it a day! --- End quote --- Hello, with the Analog Discovery (3) this works reasonably well. I have used a 1 uH coil. With a generator and a scope (with average) and some software, this is also possible. Best regards egonotto |

Today I measured a small transformer with the Peak LCR, once with the LCR40 and then with the LCR45. First LCR40... |
