IMPORTANT SAFETY INFORMATION
WHAT’S INCLUDED
FEATURES
OPERATION
• LCR Smart Tweezer style meter.
• Storage holster.
• Instruction manual.
• The LT5 range of professional quality, low cost LCR/ESR-meters are a perfect
solution for testing, identifying components and troubleshooting electronic circuits.
• The unique design combines a pair of tweezer like probes and a digital LCR-meter
in one compact and lightweight device.
• The gold-plated precision probes are designed to work with smallest SMT
components.
• It displays component type and value include a secondary parameter for capacitors
and inductors. Automatic component identication and test frequency selection
simplies measurement by elimination unnecessary trial and error time.
• Long battery life and extremely low sleep current makes this device and ideal
choice for broad spectrum of applications.
• Using it provides a quick and convenient way to test, sort and evaluate SMT
components and perform on-board measurement and debugging.

FUNCTIONS
Measurement functions:
• AM - auto identication of L, C or R
• L - inductance + resistance
• C - capacitance + resistance
• ESR - equivalent series resistance
Test frequency:
• AF - auto selection of the optimal test frequency
• Or 100Hz, 1kHz, 10kHz
• Press the button twice to turn LCR meter on.
• The device powers off automatically if it not operational for 60 seconds.
• Once operational to change test frequency press the button.
• To change measurement function press the button and hold it for 2 seconds.
• To charge the device use a standard Micro USB lead and charger or connect to a
computer.
