The new model ST-5S of the Digital Multimeter Smart Tweezers is the same device as the Smart Tweezers ST-5 but with an updated look, akin to the LCR-Reader. This update boasts a lower weight of 1 oz. and a bright screen with all the same function and features that have become synonymous with Smart Tweezers.
The unique design of Smart Tweezers combines a set of tweezer with non-magnetic stainless-steel gold-plated tweezers tips integrated with a powerful LCR-meter and bright OLED display. With automatic recognition of a measurement mode (L, C, and R) and automatic selection of the best test range allows the user to focus on the task at hand. Without the need to set-up between components, testing, sorting and evaluating components becomes much more efficient.
Inductance, Capacitance, Resistance When a component is grasped between the tweezers, Smart Tweezers automatically determines the type of component and the best test range for highest accuracy measurements. The measurement values are then instantly available on the OLED display embedded in the handle of the device. This display is split into 3 main sections. Primary display shows present reading of the main impedance component (L, C, or R). The secondary display (at the top of the LCD screen) shows present reading of the secondary impedance component, such as a parasitic resistance of the capacitor (effective series resistor ESR).
Continuity/Open Test Smart Tweezers feature a continuity test for testing circuitry. An internal beeper will sound when a resistance is below threshold or an open circuit has been detected.
Durable ProbesTweezers tips are made of gold-plated non-magnetic stainless steel and can grasp components to a 0201 size or 0.3 mm either loose or mounted.
Ergonomic Design and Convinient Controls Selecting the proper test functions and settings is simple with Smart Tweezers Joystick Navigation. Settings can be selected by pressing up, down, left or right instead of using the menu. Smart Tweezers was designed to be easy to hold and operate with just one hand, and can be set for left-handed use.
