My tests will be expanded by another relative cheap LCR measure device. Just bought an ET4410 today, will arrive end of next week. |

If the OP is in to DIY and short on cash then I'd recommend setting up their PC and soundcard as an impedance measurement rig. I have a decade old USB soundcard with 192kHz sampling and it accurately measures L, C and R from circa 2Hz to 90kHz as an impedance plot with free software like REW. The accuracy performance relates to the reference resistor tolerance used during calibration, so a 0.1% resistor allows better than 1% capacitance and inductance measurements. The measurement plot also provides enhanced information on parts, especially inductors where the first self-resonance will typically show up, as well as the shunt capacitance value. There are quite a few ESR meters suitable for DIY - I use a circuit by JAY_DIDDY_B in the projects area of this forum that properly extracts the resistive component of capacitors (no matter what type), as well as measuring resistance levels down to 100 microohm resolution to about 1milliohm accuracy. Combined with a cheapo 4-digit DMM like the Aneng AN8009, that covers rapid and accurate measurement of R and C, and a more informative measurement of L than the common practise of purchasing what can be an expensive commercial LCR meter. |

While ordering, I had the choice between "CN" and "CZ" Location - "CZ" was a little bit cheaper, so I´ve choosed this. Now I know what it means.... 8) Meanwhile I´ve expand the cap test, adding some electrolyt and ceramic capacitors. So table will start with 470p, 1n ceramic, then 47n, 100n FKP, 220n MKP, 470n Snubber MKP, 1µ MKP250V, 1µ MKP700V, 2.2µ MKP, 3.3µ MKP, 4.7µ MKP, 8.2µMKP, 10µ elektrolyt, 100µ elektrolyt, 1000µ elektrolyt. Cap-tests finished with the DE5000, U1733C and ST2830 will follow, at last the ET4410. |

Did you get it? Please share your impressions :) |
