Proster LCR Meter - Capacitance Resistance Inductance Digital LCR Multimeter with LCD Over-Range Display

Es preciso acorde a su precio, las puntas con las que viene el producto si afectan la inductancia medida y el offset zero no balancea suficiente la medicion, recomiendo usar los caimanes mas cortos para una medicion de bajas inductancias mas precisa. Las mediciones de capacitancia y resistencia son excelentes.

This is a very unique, useful tool for those constructing discrete electronic component projects. My experience, so far, is that it does what it says it does, ie., measure LCR components. It is easy to use and comes with the probes and a carrying case making an ideal product. I have wanted this kind of device for fifty years and now I have it in a easy to use economical package. Kudos to the manufacturer.

accurate meter.

低価格でも、そこそこ趣味レベルで使える印象です。2005年ごろにもらったおまけの電波時計の時刻調整機能が悪くなり、時計電波同調用のLC回路を調べてみたくて購入しました。時計のコイルとコンデンサの並列回路のコイルのインダクタンスを測定したところ3.15ｍH、コンデンサは2.2ｎFで計算すると60.45KHｚでした。60KHzほぼぴったりで少しびっくり。また別途、手持ちのフィルムコンデンサも部品記載の値と合っていましたのでなかなか使えると思います。この製品が普通に耐久性があることを期待します。

I bought this product primarily to use as an inductance meter for my growing electronics hobby test bench. Although my DMM also does capacitance, resistance and diode testing, it is handy to have a second instrument on hand to perform these functions. Fulfillment was exceptionally fast - in a matter days! The packaging was professional and slick. The unit came with all the advertised accessories including a battery. I was impressed by the overall external build quality of the meter itself - appears very solid and durable. Plus I love orange body w black body color scheme! I did NOT open up the unit to inspect internal build quality. The pop-up display allows the instrument to lie flat while providing convenient viewing of the test results and, although not back-lit, it is sufficiently large for easy reading. The unit also comes with two sets of test leads, one long and one short. The short set has alligator clips and is great for testing loose components, while the longer set has standard probe tips along with a set of attachable alligator clips. Both sets of test leads are of good quality and with all the included options, you can connect to almost anything. As far as measurement accuracy is concerned, here are a few comparative results for Proster BM4070 LCR versus Brymen BM235 DMM: 47kΩ Resistor - 45.6Ω/45.68Ω; 22nF Capacitor - 17.68nF/20.48nF; Rectifier Diode - 0.555V(forward)/0.514V(forward). Thus, reasonably good accuracy and function at an attractive price point for an electronics hobbyist!
