Multi-Function LCR Meter VA520

This multi-function LCR meter is a portable instrument designed with microprocessor control and low power consumption. It can measure 6 basic parameters: inductance L, capacitance C, AC resistance R, DC resistance DCR, dissipation factor D and quality factor Q. The multi-function LCR meter can easily communicate with PC and realize remote control through USB interface.
With battery external power supply, the multi-function LCR meter is ideal for field and portable applications, such as component inspection at fixed place, and immediate measurement by buyer and maintenance personnel.

100kHz	2.0%+5d	1.0%+5d	0.5%+3d	1.0%+5d	2.0%+5d (1M – 2MΩ)

Note: All accuracy is guaranteed by proper ratio resistor calibration and open/short calibration.
If D > 0.1, the accuracy should be multiplied by

ZC = if D << 0.1 in capacitance mode

ZL = 2πf L if D << 0.1 in inductance mode

Sub-display parameters accuracy:

Ae = impedance (Z) accuracy

Definition: Q =

Rp = ESR (or Rs)× (1+)

1.D value accuracy:De = ±Ae × (1+D)
2.ESR accuracy:Re= ±ZM × Ae (Ω)

ie., ZM = impedance calculated by or 2πf L

3.Phase angle θ accuracy:θe= ±(180/π) × Ae (deg)

Note: D: dissipation factor
Q: quality factor
ESR: equivalent series resistance
Rp: equivalent series parallel resistance
θ: phase angle

Application and After-Sales Service：
