I. Introduction

This LCR Meter is a 19999/ 9999 counts dual display, high

accuracy LCR meter, which could measure Inductance/

Capacitance/ Resistance with secondary parameters including

dissipation factor (D), quality factor (Q), phase angle (ș),

equivalent series/ parallel resistance (ESR or Rp).

This LCR Meter is fully auto ranging operation for AC

impedance & DC resistance measurement. The user could

measure the L/C/R components directly in “AUTO-LCR

“ smart mode without selecting the function key.

Components could be measured in series or parallel mode

according to the DUT (device under test) impedance

automatically.

User could select the desired test frequencies of

100Hz/120Hz/1kHz/10kHz /100kHz.

The “SORTING ” mode could help the user to make a quick

sort for a bunch of components.

The LCD display with the backlight for easy reading in dark

places.

With a 9V battery operation is standard for the meter, but a DC

9V adaptor can also be used as an optional power input.

The test data can be transferred to PC through an optional full

isolated optical USB-IR interface.

If ș> 0, the reactance is inductive. In other words, if ș< 0, the

reactance is capacitive.

There are two types for reactance. The one is the inductive

reactance XL and the other is the capacitive reactance XC.

Measurement mode

The impedance could be measured in series or parallel

mode. The impedance Z in parallel mode could be represented

as reciprocal of admittance Y. The admittance could be defined

as Y = G + jB. The G is the conductance and the B is the

susceptance.

䎃

Rs: Resistance in series mode

Xs: Reactance in series mode

Cs: Capacitance in series mode

Ls: Inductance in series mode

Rp: Resistance in parallel mode

Xp: Reactance in parallel mode

Cp: Capacitance in parallel mode

Lp: Inductance in parallel mode

Y = 1/Z = 1/Rp + 1/jXp = G+jB

- 6 -

There are two factors to provide the ratio of real part and

imaginary part. Usually the quality factor Q is used for

inductance measurement and the dissipation factor D is used

for capacitance measurement. D factor is defined as a

reciprocal of Q factor.

Q = 1 / D = tanș

Q = Xs / Rs = 2ʌf Ls / Rs = 1 / 2ʌf Cs Rs

Q = B / G = Rp / | Xp | = Rp / 2ʌf Lp = 2ʌf Cp Rp

Actually, Rs and Rp are existed in the equivalent circuit of

capacitor or inductor. If the capacitor is small, Rp is more

important than Rs. If capacitor is large, the Rs is more

important also. Therefore, use parallel mode to measure lower

value capacitor and use series mode to measure higher value

capacitor. For inductor, the impedance relationship is different

from capacitor. If the inductor is small, Rp is almost no effect. If

inductor is large, the Rs is no effect also. Therefore, use series

mode to measure lower value inductor and use parallel mode to

measure higher value inductor.

Open/short calibration

process to get the better accuracy for high/low impedance

measurement. The purpose of open/short calibration is to

reduce the parasitic effect of the test fixture.

- 7 -

ZMis defined as total impedance measured to DUT

( device under test ) by the special test fixture which has some

parasitic impedance.

ZM = (Rs + jȦLs) + ((Go+jȦCo)-1 || ZDUT)

ZDUT is the target impedance user wants to realize. It is

necessary to use the open/short calibration process to cancel

the effect of Rs+jȦLs and Go+jȦCo.

IV.Operation Instructions

To access optimum precision for all L, C and R measurements

especially at the highest and the lowest ranges, please use the

alligator test leads (TL-21) or improvised test leads applying to the

measurement for OPEN and SHORT calibration (refer to page

15~17) to reduce the parasitic effect of the test fixture before going

forward the measurement.

To secure the accuracy in specification, please only connect DUT

(device under test) to measuring socket or use TL-21 (standard

accessory) or TL-22 (optional accessory) for measurement.

If use improvised test lead for measurement please prevent using

long wire which may have incorrect result.

1. Power ON/OFF

yWhen power on, all symbols will display for 2 seconds.

yIn Auto Power off mode, APO will be shown on the display. It

will power off automatically, if without any key operation or

measurement for 5 min. Buzzer will beep three times to

remind auto power off is ready to activate and then “OFF”

display to power off.

- 14 -

yThe default setting is LCR auto mode at test frequency 1kHz.

yBattery condition is detected every second and displayed.

suggests battery capacity is full suggests power is

low and needs to be replaced a new battery.

yIf the key functions, the buzzer beeps once when key is

pressed. If the key has no function, the buzzer beeps twice

when key is pressed.

Using adaptor as power supply,

Auto Power off function disables

automatically and “APO”

disappears.

yAuto power off function is disabled automatically, when

using a 9V adaptor as the alternative power supply.

Using 9V- battery as power

supply, “APO” displays.

yAuto power off function enables when using a 9V-battery as

power supply.

2. CAL

yThis function enables the LCR meter’s internal parameters

and external connector residues to be calibrated to have

better and precise measurements.

yTo make better precision measurements on extremely high

or low impedance ranges of L,C,R, it is highly recommended

that do OPEN/SHORT calibration to reduce the parasitic

effect of the test fixture before measuring.

yNote: Remove any leads or DUT ( device under test ) from

the meter during this procedure. If leaving them connected,

will add impedance to the circuit causing the calibration to

fail indicated by FAIL showing on the display.

short calibration with TL-21 Ex. Operation for open and short

calibration with .TL-22

procedure to complete the calibration.

yWhen start the open or short calibration, it will have 30

seconds countdown shown on the display.

primary display.

yIf both calibrations are passed, press ”CAL” key again to

store the calibration value to EEPROM.(Electrically Erasable

Programmable Read-Only Memory).

Return to testing mode.

When open or short calibration

fails. “FAIL” will appear on the

primary display.

yIf fails in calibration, please double check the DUT( device

under test ) is in the right calibration position and resume the

open and short calibration procedures.

3. LCR AUTO

yThe “LCR AUTO” key selects the primary parameter

measurement function. Each press of the key will select

either Auto-LCR mode, Auto-L mode, Auto-C mode, Auto-R

mode or Auto-DCR mode*1.

yThe default setting is LCR Auto*1 mode which can check the

type of Impedance smartly and enter to the measurement

function automatically.

In LCR AUTO test mode

Press “LCR AUTO ” key

Enter Auto L mode

Press “LCR AUTO ” key

Enter Auto C mode

Press “LCR AUTO ” key

- 19 -

Enter Auto R mode

Press “LCR AUTO ” key

Enter DCR mode

Press “LCR AUTO ” key

Back to LCR AUTO test mode

yWhen Auto-L or Auto-C mode is selected, the impedance

measurement is auto ranging.

yThe primary display will show the parameter of inductance,

capacitance or resistance of DUT ( device under test ).

yThe secondary display will show the quality or dissipation

factor of DUT ( device under test ).

yThe secondary parameter will be based on the L/C/R

measurement. It means that (L + Q), (C + D)*2, (R + ș)*3 are

combined in one group respectively.

*1: If |Q| < 0.2, the Auto-R mode will be selected automatically. The

parameter on sub-display is ș.

If Q Њ0.2, the Auto-L mode will be selected automatically. The

parameter on sub-display is Q.

If Q Њ-0.2, Auto-C mode will be selected automatically. The

parameter on sub-display is D.
