| LCR vs ESR meter for in-circuit testing of electrolytic cap |
| << < (7/7) |
| sonpul:
Two diodes of different polarities connected in parallel with the DE5000 tweezers protect the device and do not interfere with measuring and testing in-circuit capacitors from .47uF to maximum. |

Check it out, you'll love it. (EPILOGUE) Miron63 vs XJW01 vs MASTECH (MS8911). Test + comparison. In-circuit measurements! |

@TimFox Can you share your experience with Quadtech 1730T? Because we have 3 units of this model and can not measure pico farads capacitors well. Best regards, JFarias |

Best regards, JFarias --- End quote --- I have been retired from that job for 10 years, so this is from memory: To measure small capacitors, we built a shielded box with four BNCs for the connections to the 1730 (not "T" model) through short coax cables, with appropriate connections for the devices under test (photodiodes in our case) inside the box. We did the open and short calibrations at the frequency range of interest at the device connections inside the box. For our application, we almost always had capacitances > 10 pF. |

Just set DE5000 to 100kHz resistance mode and you'll get ESR meter that works in circuit the same way as ESR70. |
