Frequently Asked Questions
Q: What does the M181 LCR Bridge Tester measure?
A: The M181 LCR Bridge Tester measures three core passive component parameters: Inductance (1 µH – 20 H), Capacitance (1 pF – 10,000 µF), and Resistance (0.1 Ω – 10 MΩ). It's ideal for verifying and sorting resistors, capacitors, and inductors in electronics projects.
Q: Does the M181 require any soldering or assembly?
A: No. This kit is described as "welded" (pre-soldered), meaning the module comes fully assembled and ready to use. Simply connect it to a USB 5V power source and start measuring your components.
Q: How is the M181 powered?
A: The M181 LCR meter is powered via a standard USB connection at DC 5V, making it compatible with phone chargers, power banks, computer USB ports, and other common 5V USB sources.
Q: Can I log the measurement data to a computer?
A: Yes. The M181 outputs measurement results serially, so you can connect it to a microcontroller (e.g., Arduino) or a PC with a serial interface to record and log your readings automatically.
Q: Is the measurement range selection manual or automatic?
A: The M181 features full automatic range selection — it intelligently detects the component being measured and selects the appropriate range without any manual input from the user.
