11021

A Highly Cost-effective Digital LCR Meter

The Chroma 11021 uses low harmonic-distortion phase detection technology to minimise measurement errors caused by hysteresis distortion - commonly encountered when testing magnetic components or capacitors with high dielectric coefficients. This offers a marked improvement over conventional LCR meters that rely on a half-period integration method for phase detection.

Key Features:

• Provides test frequencies of 100Hz, 120Hz, 1kHz, and 10kHz
• Equipped with a standard RS-232 interface and optional GPIB and Handler interfaces
• Fast, stable measurements ideal for both production line component evaluation and fundamental impedance testing on the bench

The Chroma 11021 is therefore an ideal choice for high-frequency coils, cores, chokes, and other passive components in incoming/outgoing quality inspection or automated production.

When testing non-linear components, odd-order harmonics (3rd, 5th, 7th, etc.) may appear in the measured voltage or current signals. If the same low-order harmonics are present in both the unknown signal and the phase detection signal, the result is a noticeable accuracy error.

To address this, the Chroma 11021 uses an eight-step sine-wave multiplier as the phase detector. This reduces the impact of low-order harmonics to a negligible level, safeguarding measurement accuracy.
