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.

5.Powering Instrument
Before beginning to operate the instrument, a power source is necessary for it to turn on. Installing Battery
5-1 Installing Battery
The LCR meter use battery to provide power to the instrument so that it can be portable. It use six standard
1.5V size batteries.
• Place the meter upside down. Open up the back-flip stand, and locate the screw that tightens the
battery compartment cover.
• Use a screwdriver to unscrew and remove the cover.
• Insert six 1.5V batteries into compartment. Note the positive (+) and negative (—) terminals as indicated
inside the battery
• compartment. Be sure to insert the battery with matching polarity.
