Overview
This chapter provides the basic operation procedures and describes names and functions on the display.
Product Introduction
LCR Pro1/Pro1 Plus (“the meter”) is a portable impedance measuring device for incoming inspection of
components, quality control, and laboratory use.
It is capable of measuring resistance, capacitance or inductance with 5 test frequencies (100Hz, 120Hz, 1kHz,
10kHz and 100kHz). It has a basic accuracy better than 0.1% for resistance and 0.2% for capacitance and
inductance measurements.
The meter has a pair of gold plated tips that can pick the SMD components with size down to 01005 (0.4mm x
0.2mm). The parasitic parameters of its probes are small and very predictable thanks to its unique mechanical
design. It significantly reduces the probability of measurement errors related to setup (such as wires, probes,
tips).
Features and Functions
Figure 1-1: LCR Pro1/Pro1 Plus Overview
The Navigation Button
The navigation button is used to browse and select different functions and parameters. It includes the “Up”,
“Down” and “Select” buttons as Figure 1-2 shows.

The navigation button can be used for shortcut operation as well. Therefore, user can switch settings quickly in
the measurement display and doesn’t need to go back and forth between the menu display and measurement
display. Detailed information is provided in Chapter 3: Making Measurements.
NOTE
When it switches from right hand operation to left hand operation, the “Up” and “Down” buttons are switched
position as well.
Turn On the Meter
To power on the meter, press the “Select” button once. The meter powers up with the most recently selected
measurement function.
Power Off
There are two ways to power off the meter:
1. Automatic power off. The meter powers off automatically if neither a measurement is performed nor any
button is clicked during the timeout period. To change timeout setting, please go to main menu ->
System -> Timeout. (Please refer to page 12: Timeout for the available options.)
2. Manual power off by selecting the turn off option from main menu as Figure 1-3 shows.
Figure 1-3: Turning off Display
NOTE
If test frequency is manually set to 10kHz or 100kHz, automatic power off may take longer to occur or not occur
at all. This is due to the meter being more sensitive at 10kHz or 100kHz. It may see parasitic values and keep
measuring even when the tips are open.
Switching to Menu Screen from Measurement Screen
When the meter is in measurement mode, user can switch it to menu screen by pressing down the "Select" button for
half second or so until the main menu screen shows up. Figure 1-4 shows the meter goes to main menu screen from
active mode (measuring components). Figure 1-5 shows the meter goes to main menu screen from idle mode (not
measuring any component in measurement mode).

Charging the Battery
The meter is powered by an internal, lithium-ion polymer rechargeable battery. It can be charged by connecting
to a computer USB port using a standard micro-B USB cable or, by using a USB power adapter. The USB power
adapter should have output voltage 5V +/- 5% with output current 100mA or greater. The USB power adapter is
available separately.
Figure 1-6: Charging the Meter
Battery Level Indicator
The battery icon in the bottom-right corner shows the battery level or charging status.
When the battery icon becomes hollow, it indicates that the battery remaining capacity is low and that it should
be recharged. The warning appears when the battery capacity is about 95% depleted. The unit is still operational
for a while, however the battery should be recharged as soon as possible.

CAUTION
Rechargeable batteries have a limited number of charge cycles and may eventually need to be replaced. The
meter battery isn’t user replaceable; it can be replaced only by an LCR Research Authorized Service Provider.

Connecting to PC
When the meter is connected to a PC via LCR Link1, it can be controlled remotely by the LCR Data Logger
software.
The LCR Link1 is a dongle style communication module that links the meter to PC. It uses a fully integrated
isolation technology to transfer data and charge the meter. This technology prevents PC noise interference so
that the meter’s performance and accuracy do not degrade when it is connected to PC.
The LCR Data Logger software can be used not only to configure the meter settings and parameters but also to
log the data to an Excel spreadsheet. It also provides some unique functions, such as:
•Data Filter: Set a threshold to prevent undesired data from being logged due to bad contact, switching
components, etc.
•Multi-component identification: The device performs step by step measurement on several components.
User doesn't need to switch parameters manually when switching from one component to another. The
device automatically sets the parameters according to the programming. It records the results and
reports Pass or Fail.

Figure 1-9: Snapshot of the LCR Data Logger Software
Refer to the user manual of LCR Data Logger Software for more information on the LCR Link1 communication
module and the LCR Data Logger software.
The LCR Link1 is an aftermarket accessory that can be purchased separately. The LCR Data Logger software and
its user manual are available for free download at http://www.lcrresearch.com.
Reset the Meter
The hardware reset function can reset the meter to factory original settings no matter which mode it is currently
in. To perform hardware reset, just press down both "Up" and "Down" buttons for more than 10 seconds until
the display is off. Releasing both buttons will reboot the meter.
NOTE
After the meter is reset, all the self-calibration data will be removed. Please perform self-calibration again if
necessary.
Cleaning the Meter
WARNING
To avoid electrical shock or damage to the meter, always keep the insides of the casing dry.
Dirt or moisture on the tips can affect measurement accuracy. Follow the steps below to clean the tips and case.
1. Shake out any dirt that may be on the tips.
2. Wipe the tips with a clean swab dipped in alcohol.
3. Wipe the case with a damp cloth and mild detergent.
NOTE
Do not use abrasives or solvents when cleaning the meter.

Self-Calibration
The self-calibration includes short and open calibration. It offsets the meter’s internal and external parasitic
parameters for better accuracy. Performing this action will help the user correct the influence for temporary
uses.

Self-Calibration
Main Menu -> System -> Self-Calibration
In self-calibration mode, the step by step instructions are shown on the display. Follow these instructions to
perform the short/open calibration:
1. When self-calibration is selected, Figure 2-11 shows on the display. Please shorten 2 tips and press any
button to start the short calibration.
Figure 2-10: Start Short Calibration
2. Once any button is pressed, Figure 2-12 shows on the display indicating short calibration is in progress.
Figure 2-11 Calibration in Progress
3. After a couple of seconds, the short calibration is completed. Figure 2-12 shows on the display. Please keep
the tips open and press any button to start the open calibration.
Figure 2-12: Start Open Calibration

14 User Manual - LCR Pro1/Pro1 Plus - ver 1.06
4. Once any button is pressed, Figure 2-13 shows on the display indicating open calibration is in progress.
Figure 2-13: Calibration in Progress
5. After a couple of seconds, the open calibration is completed. If the result is good, a calibration done
message will be shown on the display indicating the whole self-calibration process is completed. Please
press any button to return to the measurement mode.
Figure 2-14: Calibration Completed
6. If the result is out of range, a fail message will be on the display as Figure 2-15 shows. Please press any
button to return to the measurement mode. If necessary, please start the self-calibration process again from
the beginning.
Figure 2-15: Calibration Failed
NOTE
(1) It is recommended that the user performs open/short calibration before making precision measurements.
(2) When doing short calibration, please always keep the tips shorted firmly. The calibration process may fail if
the tips are in poor contact condition during the short calibration process.
(3) The distance between the tips creates small parasitic capacitance. When such distance varies (i.e. measuring
components with different sizes), the parasitic capacitance varies as well. Therefore, when doing open
calibration, please keep the tip distance as close as possible to the actual size of the component to be
measured. It can compensate for the parasitic capacitance most accurately.
(4) After the battery is completely dead or hardware reset is performed, all the self-calibration data will be
removed. Please perform self-calibration again if necessary.
