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.

Impedance accuracy Ae
The below-listed accuracies are guaranteed by the meter with normal use under the operating temperature of 18℃-28℃ and relative humidity less than 80%.
|0.1- 1Ω||1 – 10Ω||10 – 100kΩ||100k – 1MΩ||1M – 20ΜΩ||20Μ− 200MΩ||Remark|
|DCR||1.0%+5d||0.5%+3d||0.3%+2d||0.5%+3d||1.0%+5d||2.0%+5d||D < 0.1|
|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
With battery external power supply, the meter is ideal for field and portable applications, such as component inspection at fixed place, and immediate measurement by buyer and maintenance personnel.

Periodically wipe the case with a damp cloth and detergent; do not use abrasives or solvents.
Calibrate your instrument once a year to ensure that it performs according to its specifications.
Replacing the Battery
Please change the battery when the battery symbol is less than one segment.
Turn off the power of the instrument. When you change the battery, and screw off the breechblock on the battery cabinet cover, then take off it and instead the fresh battery.
