1. Overview
This product is a mini digital LCR tweezers Bridge Tester; powered by
lithium polymer battery for extended operation and standby time. It features
an OLED display for clear interface. It intelligently identifies and
accurately measures resistance, capacitance, and inductance with a wide
measurement range and high precision. The compact and elegant design allows
for easy portability. The tweezer's flexible measuring arms with detachable
gold-plated tips ensure flexible and reliable operation. It is suitable for
various SMD or other LCR parameter measurements.
The product offers user calibration learning mode, allowing users to
calibrate based on standard resistors. Factory calibration data can be
restored by resetting to factory settings if needed.
2. Safety Precautions
To prevent electric shock, fire, or personal injury, please read the safety
precautions before use.
(1) Do not apply input voltage during measurement. Do not measure "live
circuits." Disconnect power before online measurement and ensure all
capacitors in the circuit are discharged.
(2) Discharge capacitors before measuring capacitance.
(3) Avoid prolonged use or storage in high temperature, high dust, or direct
sunlight environments.
(4) Do not use this product in explosive gas, vapor, or humid environments.
