LCR Pro1/Pro1 Plus

World’s first tweezer-style LCR meter with 0.1% accuracy and PC connectivity
The LCR Pro1/Pro1 Plus integrate 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.

A Breakthrough in Accuracy
LCR Pro1/Pro1 Plus deliver high accuracy once found only in high-end
desktop LCR meters. It provides basic accuracy 0.1% for resistance and0.2% for capacitance and inductance with 5-digit resolution. Each device isfully calibrated during production and shipped with NIST (NationalInstitute of Standards and Technology) traceable calibration certificate.
The test frequencies can be selected from 100Hz to 100kHz. 100kHz isideal for measuring small inductance under 1uH. The test voltage can beselected 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 siliconchips from being active during measurement.

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 andreliably, 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.

PC Communication
LCR Pro1/Pro1 Plus 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 fordelivering power and data safely and blocking the noise from PC
effectively. Therefore it ensures that the device performance andaccuracy don’t get degraded when it is connected to PC.

Multiple Functions
LCR Pro1/Pro1 Plus are able to test additional component
parameters such as ESR, DCR, D, Q, θ, etc. They can also test
diode and indicate polarity and forward voltage/current.
LCR Pro1 Plus offers an additional LED testing function. In LED
testing, it lights up the LED and displays its electrical parameters,such as polarity, voltage and current. When testing bi-directionalLEDs, the electrical parameters will be displayed in each direction.
