Test Frequency Functions
Test frequency can greatly affect the results of measurement readings,
especially when measuring inductors and capacitors. This section provides
some recommendations and suggestions to consider.
Capacitance
When measuring capacitance, selecting the right frequency is important
in obtaining the most accurate results. Generally a 1kHz test frequency is
used to measure capacitors that are 0.01μF or smaller. For capacitors that
are 10μF or larger, a lower frequency of 120Hz is used. Following this trend,
high-test frequencies are best for testing very low capacitance components.
For large capacitance components, low frequency would be optimal.
For example, if the capacitance of the component is in the mF range, then
selecting 100Hz or 120Hz for the test frequency would give more accurate
results. The results will also be obvious because if the same component
was tested with 1kHz or 10kHz, the measured readings may look erroneous
on the display. In all cases, it is best to check with the manufacturer's data
sheet in order to determine the best test frequency to use for measurement.
Inductance
Typically a 1kHz or 10kHz test frequency is used to measure inductors
that are used in audio and RF circuits because these components operate
at higher frequencies. However, a 120Hz test signal is used to measure
inductors that are used for applications such as lter chokes in power
supplies, which are typically operated at 60Hz AC (in US) with 120Hz
lter frequencies. In general, inductors below 2 mH should be measured
at 1kHz frequency while inductors above 200H should be measured at
120Hz. In all cases, it is best to check with the manufacturer's data sheet
in order to determine the best test frequency to use for measurement.
Selecting Test Frequency
The meter has ve test frequencies: 100Hz/120Hz/1kHz/10kHz/100kHz. Press
the FREQ button to scroll through the ve frequencies sequentially.
Note: The test frequency can affect the accuracy of the results depending
on what frequency is selected as well as what type and value of component
is being measured or tested.

Primary Impedance with Secondary Parameter Test
The default test mode for this meter is Auto-LCR Mode, which checks the
type of impedance and automatically enters L/C/R Mode. The secondary
parameter will follow the L/C/R measurement, meaning that (L+Q), (C+D)*,
(R+θ)** are combined in one group respectively.
1. Press the FUNC button to switch from Auto-LCR Mode to Auto-Lp
Mode, Auto-Cp Mode, Auto-Rp Mode, and DCR Mode.
Note: When Auto-Lp or Auto-Cp Mode is selected, the impedance
measurement is auto ranging. The primary LCD display will show the
inductance or capacitance of DUT (device under test); while the secondary
LCD display will show the quality or dissipation factor.
2. Press the button to display the D/Q/θ/ESR value. When Auto-R
(ACR mode) or DCR mode is selected the secondary parameter
is omitted.
* When Auto-LCR mode is active,
Device Under Test Display
the secondary parameter will
show the equivalent resistance in
parallel mode (Rp) to replace the
D factor if the C measured value
of the DUT is less than 5pF.
** Auto-LCR mode only. During
Auto-R Mode or DCR Mode,
the secondary parameter is
not available.
Series or Parallel Functions
Just as test frequency can greatly affect measurement results, selecting
between series or parallel measurement mode can also affect the accuracy
of the meter, especially for capacitive and inductive components. This
section provides some recommendations and suggestions to consider.
www.GlobalTestSupply.com
continued...
14
Capacitance
Most capacitance measurements will obtain best results with parallel mode
selected. The majority of capacitors have a very low dissipation factor
(high internal resistance) compared to the impedance of the capacitance. In
these cases, the paralleled internal resistance has negligible impact on the
measurement. There will be some cases where series mode would be used
for a capacitance measurement, or the readings will appear inaccurate.
Series mode is useful when large capacitors have higher dissipation factor
and lower internal resistance.
Inductance
Most inductance measurements will obtain best results with series mode
selected. In series mode, accurate Q (quality factor) readings can be
obtained from reading low Q inductors and ohmic losses are signicant.
There will be some cases where parallel mode would be used for an
inductance measurement, for example iron core inductors operating at
higher frequencies where hysteresis and eddy currents become signicant.
Series/Parallel Measurements
When any L/C/R function is selected, the default measurement will be
automatically selected. If the impedance is greater than 10kΩ, parallel
mode will be selected, and "Lp/Cp/Rp" will display on the LCD screen. If
the impedance is less than 10kΩ, series mode will be selected, and
"Ls/Cs/Rs" will display on the LCD. When the Parallel/Series/Right Button
is pressed, the impedance measurement will be set in series mode or in
parallel mode sequentially.
Data Hold
1. While taking a measurement, press the HOLD button to freeze the
current readings on the display.
2. While in this mode a "HOLD" symbol will appear.
3. Press the button again to resume normal operation.
Note: When the Data Hold feature is active all buttons except the power &
backlight buttons are disabled.

Relative Mode
1. To reserve the current DUT readings (DCUR) on the primary display
as a reference value (DREF), press the button.
2.
The ∆ symbol will then appear on the LCD screen indicating this function
is now active. The secondary display will show the percentage of the
relative value (REL%).
3. Press the button again to show the reference value (DREF) on the
primary display; the ∆ symbol will start to blink.
REL% = (DCUR – DREF) / DREF x 100%
Note: The percentage range is -99.9% to 99.9%. When the relative value
is larger than double the reference value (DREF), the "OL%" symbol will
appear on the secondary display.
4.
Press and hold down the button for approximately 3 seconds to
exit relative mode and resume normal operation.
Accuracy Discrepancies
In some special cases, inaccuracies may occur in the measurement of
capacitive, inductive, and resistive components. This section provides
some recommendations and suggestions to consider.
Capacitance
It is strongly recommended to have the dissipation factor low when measuring
capacitors. Electrolytic capacitors inherently have a higher dissipation factor
due to their normally high internal leakage characteristics. In some cases, if
D (dissipation factor) is excessive, measurement accuracy may degrade and
even read out of specication.
Inductance
Some inductors are intended to operate at a certain DC bias to achieve a
certain inductance value, however this meter cannot produce such a biasing
scheme. External biasing should not be attempted because external power
would be applied to the instrument and cause serious damage to the meter.
Therefore, in some cases, the inductance reading may not agree with
manufacturer's specication. It is important to check if the specication
pertains to DC biasing or not.

Resistance
When measuring resistance of devices, it is important to know that there are
two types or ways of measurement. One type is DC resistance measurement.
Another type is AC resistance measurement. The LCR meter provides both
types of measurement.
Before using the meter to measure resistance, please verify whether
the DUT (device under test) requires DC or AC resistance measurement
method. Depending on the method, results will vary greatly.
Guard Terminal
One of the input sockets and terminals is labeled as "GUARD". This
terminal does not have to be used in all instances for the meter to provide
measurements. But in some instances, it is very useful. Guard terminal
generally serves two purposes.
If user is using test leads, the guard terminal can be used to connect to
the shielding of the test leads. Doing so can be useful when making large
resistive component measurements. For example, when measuring a 10
MΩ resistor with test leads, at the high range the reading may seem to be
unstable as a few digits may continuously be changing. Having the shield
of the test leads connected to the guard terminal will help stabilize the
reading in some instances.
Guard terminal is also used to minimize noise and to help minimize parasitic
effects coming from the component being measured, thus allowing high
precision results.
Calibration Mode
It is recommended to regularly calibrate this meter to improve the accuracy
of high/low impedance measurements.
Note: You will need a shorting bar or a short piece of conductive metal
(i.e. paper clip) to complete the calibration procedure.
1. Be sure nothing is connected to the meter, and turn it on.
2. Press and hold down the CAL button for 2 seconds to enter
calibration mode.
3. The screen will display "OPEN", indicating the input terminals have
nothing connected.

Sorting Mode
Sorting mode helps the user quickly sort through multiple components.
Select the primary measurement mode (L/C/R) based on the type of
components to be measured. Insert the component to be used as the
standard or good reference value that will be used for testing against all
other components.
Note: The meter needs a component connected to either the input sockets
or terminals for sorting mode to activate.
1. When ready, turn the meter on and press the SORTING button to
enter sorting mode.
