Summary of ST-5S SMART TWEEZERS™ FOR ON-BOARD L/C/R MEASUREMENTS AND PCB TESTING
The ST-5S Smart Tweezers is a handheld LCR meter designed for on-board testing of surface-mount and leaded components without removal. It features gold-plated tweezers, an OLED display, and automatic range/frequency selection. The device supports variable test signals, tolerance settings, continuity/diode testing, and semi-automatic offset subtraction. Powered by a battery and controlled via a joystick interface, it includes NIST-traceable calibration for professional accuracy.
Parts used in the ST-5S Smart Tweezers:
- Precise gold-plated tweezers
- Digital LCR meter
- OLED display
- Battery-powered unit
- Integrated insulated measurement head
- Joystick-like navigation control
This intelligent measurement tool is a new type of handheld LCR meter that can quickly test, identify, and measure board-mounted surface-mount and leaded devices without the need to remove them from a circuit board.
Saelig Company, Inc. has introduced the ST-5S Smart Tweezers™ for on-board inductance, capacitance, and resistance measurements and PCB testing. The ST-5S tweezers are a valuable solution for quickly testing and identifying surface mount devices, as well as for troubleshooting complex electronic PCBs. Its unique mechanical and electronic design combines a pair of precise gold-plated tweezers and a digital LCR meter in compact, lightweight, battery-powered instrument. Smart Tweezers™ automatically detects L, C, or R measurements and selects the correct measurement range and test frequency for high accuracy readings. Component type, value, and more detailed component analysis, such as Z and ESR, are all displayed on the instrument’s OLED display.
Surface mount devices are very small and have no wire leads, making it more difficult to test and identify SMDs than conventional leaded components. Smart Tweezers™ also gives users an easy way to sort tiny, loose components. Precise tips reliably contact even the smallest SMD components and take measurements from board-mounted devices. Smart Tweezers™ can also be used to test conventional components with wire leads that may not be long enough to insert into conventional test terminals. The integrated, insulated measurement head allows the operator to use one hand (left or right) for measurements to simplify probe placement tasks.
The ST-5S is for built for professional engineers since it comes with a NIST-traceable calibration certificate. The ST-5S allows users to change the test signal (with 0.5 and 1.0 Vrms), as well as variable tolerances of 1%, 5%, 10%, and 20%. This device also performs continuity and diode testing and shows active and reactive impedance component readings on the display. A feature that saves time for users is that a semi-automatic offset subtraction feature automatically removes parasitic readings after set-up. The ST-5S is controlled by joystick-like navigation; pushing the button directionally will change the test mode, test signal, etc., and pressing the joystick directly opens a menu to allow more customized measurements and features such as changing the screen orientation.
