LCR Pro1 / LCR Pro1 Plus
Introduction and Application Guide
rev1.6
Made in Canada

A Highly Integrated Device
The LCR Pro1 integrates a pair of tweezers like
probes and a LCR meter into one compact,
lightweight, battery powered device. It is an all-in-
one miniature device that provides a simple and
efficient solution for not only measuring SMD
components, but also making in-circuit debugging.
The Pro1 is an ideal device for many applications
including components verification and sorting,
production lines, laboratory and service center, in-
field repair and more.

Pro1 Plus Key Features
rev1.6 4
•Automatic LED testing
–Display LED polarity, voltage
and current
•Ultra sensitivity to very small
inductors
–Be able to sense inductors
down to 1nH.
•All Pro1 features
–Please see page 3 for details.

The Pro1 delivers high accuracy once found only in
high-end desktop LCR meters. It provides basic
accuracy 0.1% for resistance and 0.2% for capacitance
and inductance with 5-digit resolution.
Each device is fully calibrated on production and
shipped with NIST (National Institute of Standards and
Technology) traceable calibration certificate.
The test frequencies can be selected from 100Hz to
100kHz. 100kHz is ideal for measuring small inductance
under 1uH.
The test voltage can be selected from 0.2Vrms to
1.0Vrms. 1.0Vrms allows precision measurements of
ceramic capacitors with high dielectric constant (K),
such as X5R type. 0.2Vrms is specially designed for in-
circuit debugging because it is low enough to prevent
the silicon chips from being active during
measurement.

A Breakthrough in Accuracy

Very Wide Measurement Range
•Provides wide measurement range that
covers almost all the SMD components:
–R: 20mΩto 10MΩ;
–C: 0.2pF to 10mF;
–L: 10nH to 1H (for Pro1);
–L: 1nH to 1H (for Pro1 Plus).
•Significantly improves the accuracy for
very small inductors, which are from a
couple of nHs to hundreds of nHs.
–This is a very important advantage of the Pro1
as these small inductors are widely used in
the RF industry, but usually only expensive
desktop LCR meters are able to measure such
small values.
–The left two pictures show the measurement
result of a 100nH Murata LQW series RF
inductor:
•Desktop meter: 113.44nH
•Pro1: 114.94nH, accuracy: 1.3%

Ultra-Precise Tips
The redesigned gold-plated tips are more
precise than ever. You can use them to
pick up and measure SMD components
quickly and reliably, even for the most tiny
parts with 01005 size.
Thanks to the sharp tips, you can easily
reach the component under test without
touching the adjacent components during
in-circuit troubleshooting even in a very
crowded area.

Handy Shortcuts
The Pro1 is full of handy shortcuts to help you
switch all kinds of parameters faster and easier.
During the measurement, you can quickly select
different settings by single clicking, double clicking
or holding the navigation button.

PC Communication
The Pro1 is able to make measurement and
charge battery simultaneously when it connects
to PC via the LCR Link1, a USB dongle style
communication module.
The Link1 is built with a fully integrated isolation
technology for delivering power and data safely
and blocking the noise from PC effectively.
Therefore it ensures that the device performance
and accuracy don’t get degraded when it is
connected to PC.

Intuitive LCR Data Logger Software
The LCR Data Logger is an easy-to-use Windows based software that is downloadable for free
from our website. It provides an intuitive user interface on PC to remote control the Pro1 that is
connected to PC via the LCR Link1. It configures the Pro1 parameters and logs the measurement
results to an Excel spreadsheet.

LCR Visual Measurement
rev1.6 11
How it works:
Visual measurement is a unique feature that indicates the test points on the
picture of the board you are testing. When running visual measurement, LCR Data
Logger displays both GUI and PCB picture. It can:
Automatically set up device parameters for each component for testing.
Indicate the component location on the picture.
Once the test is completed, display the test result on both GUI and picture.
Record all the test parameters and results to a Excel spreadsheet.
Benefits:
•Run test more conveniently as the test points can be easily found on the picture.
It improves productivity especially for the applications that require duplicated
measurements, such as production lines, repair center, etc.
•All the test parameters are programmed automatically according to the visual
profile. After testing, the results are recorded in a Excel spreadsheet. It reduces the
possible measurement errors due to manual setup mistakes by the operator.
