4-5 Measuring Mode Selection

4-5-1 Auto LCR Mode

After power-on, the meter is in the Auto LCR mode as a default setting, and shows [AUTO LCR] on the display. The meter automatically selects a function, parameter, and series/parallel mode. The function and the sub parameter on the sub display will be selected based on the following conditions.

Conditions for automatic selection of functions and sub parameters.

Functions Sub parameters Example
-11.3° ≤ ≤ 11.3°	Resistance θ	Fig. 4-5-1-1
> 11.3^ Inductance Q Fig. 4-5-1-2
< -11.3^ Capacitance D Fig. 4-5-1-3

If C < 5 pF, Rp is shown on the sub display.

Selection of series/parallel mode depends on the total equivalent impedance measured. (Refer to 4-7)

Note:

S/P button and D/Q/θ button are not available in the Auto LCR mode.

Fig. 4-5-1-1

Fig. 4-5-1-2

Fig. 4-5-1-3

4-5-2 Manual LCR Mode and DC Resistance Measurement

As already described, the default setting is the Auto LCR mode after power-on, the main function can be switched to the manual LCR mode or DC resistance mode by pressing the L/C/R AUTO/MANU button.

Pressing this button ( ) sequentially switches the functions as follows. Auto LCR mode Ls or Lp function Cs or Cp function Rs or Rp function DCR function Auto LCR mode

Example of resistance measurement

In the manual LCR mode, the meter automatically selects the series/parallel mode depending on the total equivalent impedance measured similarly to the Auto LCR mode. (Refer to 4-7)

The function of Ls, Lp, Cs, or Cp in the manual LCR mode shows following parameters, being switched by pressing D/Q/θ button.

Functions Selectable parameters
Ls, Cs	Dissipation factor (D), Quality factor (Q), Equivalent series resistance (ESR), and Phase angle (θ)
Lp, Cp	Dissipation factor (D), Quality factor (Q), Equivalent parallel resistance (Rp), and Phase angle (θ)

Note:

- Usually quality factor (Q) is used for inductance measurement. Inductor with higher Q has lower resistance component. Usually dissipation factor (D) is used for capacitance measurement. Capacitor with lower D has lower resistance component.

Quality factor (Q)

= Inductance (L) component / Resistance (R) component Dissipation factor (D)

= Resistance (R) component / Capacitance (C) component

- ESR is used for measuring equivalent series resistance of a capacitor under a measuring frequency.

4-6 Measuring Frequency Selection

The meter provides 5 different frequencies (100 Hz/120 Hz/1 kHz/10 kHz/100 kHz)

for more accurate measurement.

The default setting is 1 kHz, and the measuring frequency can be selected by pressing the TEST FREQ button as follows.

1 kHz 10 kHz 100 kHz 100 Hz 1 kHz

Note:

The LCR impedance scale ranges and accuracies depend on the measuring frequency.

Refer to the accuracy table in Chapter 9.

4-7 Series/Parallel Mode

When measuring L/C/R with multiple element in its equivalent circuit, an appropriate measuring mode needs to be selected, assuming actual circuit to be measured.

Select the series mode if a series circuit is assumed, or select the parallel mode if a parallel circuit is assumed.

In the Auto LCR mode or manual LCR mode, the meter automatically selects the series/parallel mode depending on the total equivalent impedance measured. (The display shows [AUTO].)

10 kΩ and lower: Series mode (Ls/Cs/Rs)

Higher than 10 kΩ: Parallel mode (Lp/Cp/Rp)

In the manual LCR mode, pressing S/P button manually switches assumed series/parallel mode.

When manually selecting series/parallel mode, the display turns [AUTO] off.

4-8 Auto Range Selection

A measuring range in each function will be automatically selected, and cannot be manually selected.

4-9 Data Hold

Press HOLD button to freeze present reading for later view. (The display shows [HOLD].) Even if the DUT is disconnected from the measuring terminal, the current reading will remain on the display.

Press the HOLD button again to disable the data hold feature and go back to the normal measurement mode. (The display turns [HOLD] off.) Note:

When the reading is indefinite, the data hold feature is not available.

4-10 Relative Measurement

Relative measurement allows you to read directly the deviation in % from a reference value.

Pressing the button activates the relative mode, and the display turns [ ] on.

Note:

This function is not available in the Auto LCR mode.

Nor can it be activated when the reading is outside of the meter limits (Ex. [OL] is displayed.).

The meter uses the following formula to calculate relative measurements.

REL% = (DCUR - DREF) / DREF * 100%

REL% = Difference in percent

DCUR = Device currently under test

DREF = Device used as a reference

To enter the relative mode, proceed as follows.

1. Perform the OPEN/SHORT calibration. (Refer to the section 4-11).
2. Select a function from L, C, R, or DCR.
3. Connect a device to the measuring terminals as a reference and wait until the readings become stable.
4. Press the button to save the reading as a reference value.

Now, the display indicates [] , and the sub display shows [0.0%] .

1. Remove the reference device, then connect a DUT to the measuring terminals.

The main display shows the value of the DUT and the sub display shows the difference from the reference in %.

Pressing the button again shows the reference value saved in the previous step. You can check the reference value. ([ ] is blinking.)

Pressing the button again allows you to measure in the relative mode.

1. Repeat Step 5 for each DUT.

Note: The range for the difference in percent is -99.9% to 99.9%. If the DUT falls outside that range, the sub display will show [OL].

1. To exit this mode, press the button for 2 seconds.

4-11 OPEN/SHORT Calibration

The OPEN/SHORT calibration before measurement reduces the parasitic effect of the test fixture to get better accuracy especially for high/low impedance measurement. (For the calibration principle, see 4-15-3.)

4-15 MEASURING PRINCIPLES

4-15-1 What is impedance?

Impedance Z extends the concept of resistance to AC, which is mathematically handled as a vector quantity on a complex plane. As shown, the impedance vector consists of the real part (the resistance R) and the imaginary part (the reactance X). Series impedance Zs can be represented as Rs + jXs in Cartesian form, and also can be represented as |Zs| (magnitude and phase angle) in the polar form. The figure shows a mathematical relationship between Rs, Xs, |Zs| , .

$$ Z s = R s + j X s \text { or } | Z s | \angle \theta $$

$$ R s = | Z s | \cos \theta $$

$$ X s = | Z s | \sin \theta $$

$$ X s / R s = \tan \theta $$

$$ \theta = \tan^ {- 1} (X s / R s) $$

There are two types of reactance. One is inductive reactance X_L , and the other is capacitive reactance X_C .

If > 0 , the reactance is inductive. If < 0 , the reactance is capacitive.

The inductive reactance (XL) and the capacitive reactance (XC) can be defined as follows.

$$ X _ {1} = 2 \pi f L $$

$$ X _ {c} = 1 / (2 \pi f C) $$

where:

L = Inductance

C = Capacitance

f = signal frequency

4-15-2 Impedance measurement

Impedance can be measured in series or in parallel. In parallel mode, impedance can be represented as reciprocal of admittance (Y).

The admittance can be defined as Y = G + jB .

where: G = Conductance B = Susceptance

Series impedance Parallel admittance

Rs = Series resistance

Xs = Series reactance

Cs = Series capacitance

Ls = Series inductance

Rp = Parallel resistance

Xp = Parallel reactance

Cp = Parallel capacitance

Lp = Parallel inductance

	Series Parallel Dissipation factor
Capacitance	Cs=Cp(1+D^2) Cp=	Cs/(1+D^2)	D=Rs/Xs= CsRs D=G/B=G/( Cp)=1/( CpRp)
Inductance	Ls=Lp/(1+D^2) Lp=	Ls(1+D^2)	D=Rs/Xs=Rs/( Ls) D=G/B= LpG= Lp/Rp
Resistance	Rs=RpD^2/(1+D^2) Rp=	Rs(1+1/D^2) —
Q = Xs/Rs = 2πf Ls/Rs = 1⁄2πf CsRsQ = B/G = Rp/ | Xp| = Rp/2πf Lp = 2πf CpRp

To understand the ratio of resistance and reactance, it is important to consider Quality factor (Q) and Dissipation factor (D). Usually, Q is used when measuring inductance and D is used when measuring capacitance. Q is defined as the reciprocal of D.

$$ Q = 1 / D = \tan \theta $$

Both Rs and Rp are part of the equivalent circuit of capacitors and inductors.

To measure capacitance and inductance, refer to the settings as shown in the table below.

	Value Setting
Capacitance	Low Parallel
	High Series
Inductance	Low Series
	High Parallel

For details, refer to the section 4-7.

4-15-3 Principle of OPEN/SHORT calibration

Z_M is defined as total impedance measured to a DUT by a test fixture which has some parasitic impedance.

Z_M = (Rs + j Ls) + ((Go + j Co)^-1 // Z_DUT)

Z_DUT is impedance of the DUT.

The OPEN/SHORT calibration reduces the effect of (Rs + jωLs) and (Go + jωCo).
