LCR Meters

  1. Jul 19, 2011 #1
    This might be a stupid question, but here goes. I'm trying to build my first radio and I want to know if LCR meters are capable of measuring current and voltage or if I have to purchase a separate multimeter to perform those measurements. Any help would be appreciated.

    Some DVMs have these functions built in.

    I have a B&K handheld meter that I use for LRC, and my Fluke DMM has a capacitance measuring capability. I haven't seen the L measuring function on simple DMMs, but they could exist. You might try a Google Images search on DMM + LCR.

    LCR meters are typically specialized for impedance measurement (via measuring AC voltage and current). Specially the LCR measuring portion is not a general voltmeter/ammeter like a DMM.

    However has others have stated, you can get low cost "LCR-like" capabilities in in relatively low cost hand-held DMMs. The circuitry to do this is usually separate from the DC measurement circuity but it's cheap enough to implement both so all's good. For typical hobby and low-ish accuracy work, they work great.

    If you need high accuracy, extreme values (e.g. femto-farads), or phase-related factors like dissipation factor or Q, then often you need a more dedicated LCR meter. Which can get pricey.
