Frequently Asked Questions
Q: What does the M181 LCR Bridge Tester Module measure?
A: The M181 LCR Bridge Tester Module measures three key passive component values: inductance (1 µH – 20 H), capacitance (1 pF – 10,000 µF), and resistance (0.1 Ω – 10 MΩ). It is ideal for sorting components, verifying component values, and supporting electronics DIY projects and circuit development.
Q: Does the M181 LCR meter come fully assembled or do I need to solder it?
A: This kit comes pre-welded (fully soldered), meaning no additional soldering is required. Simply power it via USB and it is ready to use right out of the box.
Q: How is the M181 LCR tester powered?
A: The M181 LCR Bridge Tester is powered via a standard USB port (DC 5V), making it easy to use with a laptop, desktop computer, USB hub, or USB wall adapter — no proprietary power supply needed.
Q: Can I log measurement data from this LCR tester to a computer?
A: Yes! The M181 module features a serial data output function, allowing you to transmit measurement results to a PC for data logging, analysis, or integration with other electronics systems.
