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 theparallel mode if a parallel circuit is assumed.
In the Auto LCR mode or manual LCR mode, the meter automaticallyselects 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.

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 andwait until the readings become stable.
4. Press the ⊿ button to save the reading as a reference value.
Now, the display indicates [Δ], and the sub display shows [0.0%].

4-8 Auto Range Selection
A measuring range in each function will be automatically selected, andcannot be manually selected.
4-9 Data Hold
Press HOLD button to freeze present reading for later view. (Thedisplay shows [HOLD].) Even if the DUT is disconnected from themeasuring 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 [Δ] 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.).

― 11 ―

5. Remove the reference device, then connect a DUT to themeasuring 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 savedin the previous step. You can check the reference value. ([Δ] isblinking.)
Pressing the ⊿ button again allows you to measure in the relativemode.
6. 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].
7. To exit this mode, press the ⊿ button for 2 seconds.

4-15 MEASURING PRINCIPLES
4-15-1 What is impedance?
Impedance Z extends the concept of resistance to AC, which ismathematically handled as a vector quantity on a complex plane.
As shown, the impedance vector consists of the real part (theresistance R) and the imaginary part (the reactance X). Series
impedance Zs can be represented as Rs + jXs in Cartesianform, and also can be represented as |Zs| ∠ θ (magnitude andphase angle) in the polar form. The figure shows a mathematical
relationship between Rs, Xs, |Zs|, θ.

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.

There are two types of reactance. One is inductive reactance XL,
and the other is capacitive reactance XC.
If θ > 0, the reactance is inductive. If θ < 0, the reactance iscapacitive.
The inductive reactance (XL) and the capacitive reactance (XC)
can be defined as follows.
XL = 2πƒL
XC = 1 / (2πƒC)
where:
L = Inductance

Cp=Cs/(1+D2)

Q = Xs/Rs = 2πf Ls/Rs = ½πf CsRs
Q = 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 θ― 20 ―
