3. Functional Description

3-1 Introduction

The LCR meter could measure Inductance/Capacitance/Resistance with

secondary parameters including dissipation factor(D), quality factor(Q), phase

angle(θ), equivalent series/parallel resistance(ESR or Rp). The meter is fully auto

ranging operation for AC impedance & DC resistance measurement. It means the

user could measure the L/C/R components directly at AUTOLCR smart mode

without changing the function key. User could also select the target test

frequencies of 100Hz/120Hz/1kHz/10kHz/100kHz depending on DUT(device

under test) type. Components could be measured in series or parallel mode

according to the DUT impedance automatically.
