This is a very powerful compact test package. It is quick to use. Has a deep menu structure to expand its usefulness. You can set it to check for specific component or let is figure out what the component is. In many cases for non-resistor components will provide the component size along with the internal resistance. Excellent for sorting through components and for trouble shooting circuits.

Product is excellent, easy to use, and impressively accurate. It is able to properly measure the inductance of 1 inch of wire accurately, which no other instrument at the university where I work could measure. The many parameters it can measure make it very useful. While it is somewhat more expensive than other units, the cost is more than justified by the quality and capability it offers. I cannot say how well it lasts, or the battery life, as I have not had it long enough. I am waiting to see how well it lasts, and am very hopeful it is superior to competitive products I have purchased previously that became unusable after a month or two, despite light use. The only improvement I could suggest is a rounding option. The bouncing of the least significant of the five digit display with small value measurements can be distracting. The other issue is it would be nice to have a manual for operating the instrument included in the package rather than having to download it on-line. These are minor issues with an excellent instrument that is well worth the price.

LCR Research's LCR-Pro1 Handheld LCR Meter is an excellent, tweezers type device for testing and troubleshooting SMD circuits. It is accurate and super easy to use. By automatically identifying resistors, capacitors, and inductors, it chooses the best properties to display without manual range adjustments.The OLED display is 0.96" which is the largest size and resolution I can find in this form factor. The menu and measurement results are very easy to read. The display can be switched to left or right hand operation and its brightness can be adjusted in menu.The gold-plated tips are replaceable. They are shaped to hold loose SMD components, or test the components already soldered to a PCB. If you’ve ever tried to measure SMD components with a typical multimeter - balancing the probes on the SMD components pins to ensure reliable contact - the value of the LCR-Pro1 tweezer type probes is apparent - with LCR-Pro1 meter I had no problem identifying a few parts mixed together on my workbench.The LCR-Pro1 graphic menu is navigated with a 3-way joystick. The joystick control is very convenient and easy to use. The joystick shortcuts - single or double click – are a fast and intuitive way to change parameters without using a menu.The LCR-Pro1 measures both the real and imaginary impedances and to display the theta angle for resistance measurements, series or parallel equivalent resistance or D for capacitance and series or parallel equivalent resistance or Q for inductance measurements. It has many additional functions like continuity, component sorting, diode polarity and direct current measurement.The LCR-Pro1 saved me a lot of time debugging my latest surface mount electronic design projects. I have lots of tiny 01005 and 0201 SMD components placed close to each other on PCB. Probing with the LCR-Pro1 precise tweezers probes is faster and easier compared LCR meters I’ve used before. One handed operation allows the use of another hand to hold and properly position PCB during in-circuit testing. Test voltage can be selected between 0.20 V, 0.50 V and 1.0 V. for accurate in-circuit measurements without turning on semiconductor junctions I use 0.2V setting. The 1.0V is a best choice to measure some types of ceramic capacitors, such as X5R, whose capacitance varies with applied voltage.Another function I really liked is self-calibration. It can be done simply by shortening and opening tips. After self-calibration, I saw parasitic parameters were reduced significantly. For example, resistance was dropped down below 1 milli-ohm when two tips are closed together. It improves measurement results especially for small resistors, inductors and capacitors.The LCR-Pro1 uses a Li-ion rechargeable battery and can be charged from any USB port. The battery life is pretty good. I used my device around one hour a day for a week and it still shows 80% battery capacity.The LCR-Pro1 is a top quality handheld LCR meter for measuring SMD components. I do not use it all the time, but when I do need it, I can’t imagine using any other tool.
