    The Chroma 11021/11021-L are very cost-effective digital LCR Meters, providing 100 Hz, 120 Hz, 1 kHz, and 10 kHz test frequencies for the 11021 and 1 kHz, 10 kHz, 40 kHz, 50 kHz test frequencies for the 11021-L. Standard RS232 interface, optional GPIB & Handler interface, high speed and stable measurement capabilities allow the Chroma 11021/11021-L to be used for both component evaluation on the production line and fundamental impedance testing for bench-top applications. Chroma's 11021 and 11021-L LCR meters have the flexibility to provide multi-parameters over wide frequency and voltage ranges

    Bin-sorting Function
    The 11021/11021-L provides 8-bins sorting function with bin count statistics. It is very convenient for magnetic core sorting or capacitor sorting. And the bin count statistics can be used to analysis distribution of tested results or production quality.

    HI/GO/LO Comparator
    The 11021/11021-L has a comparator function to judge HI/GO/LOW of capacitance measured results, and to judge GO/NG of D factor. And an alarming beeper for total GO/NG judge.

    Trigger Delay Time
    For large capacitance measurement in automatic production, a RC (meter output resistance and unknown capacitance ) delay time for test signal transient is necessary. The 11021/11021-L provides trigger delay time for it, and is convenient for automatic equipment timing adjustment.

    Input Protection
    Un-discharged device (generally, a capacitor) under test is the most general reason causes destroy on a LCR Meter. The 11021/11021-L using an excellent input protection circuit to prevent it from this kind of damage.

    Open/Short Zeroing
    General low-end LCR meter just provides zero offset to substrate stay capacitance, residual resistance or residual inductance only for C, R, L measurement which can not accurately measure Q (quality factor) for L, R measurement and D (dissipation factor) for C measurement. The 11021/11021-L provides full open/short circuit zeroing function.

    Lower Harmonic-distortion Phase-detection Technology
    The 11021/11021-L uses lower harmonic-distortion phase detection technology to reduce measurement inaccuracy caused by hysteresis distortion in magnetic component or high dielectric-coefficient capacitor measurement. The 11021-L is the ideal selection for high frequency coil, core, choke quality inspection, and automatic production.

    The frequency spectrum of half period square wave is shown as figure 1 and 2, and non-ignorable 3rd, 5th order harmonics are included. For non-linear devices under testing, odd-order (3rd, 5th, 7th, etc.) harmonics may occur in measured potential or current signals. Then, this phase-detection method will cause obvious accuracy error because of same low order harmonics are included in both unknown signal and phase-detect signal. The 11021/11021-L uses eight steps sine-wave multiplier as phase detector to reduce low-order harmonics affection to an ignorable level.
