Precision Meter Bokar Smart Tweezers ST-AS
The integration of SMD probes and the display, combined with an automatic recognition of a measurement mode (R, C, and L) and the best measurement range allow the user to focus on the component under test. As a result, testing, sorting and evaluation of components become much more efficient.
- Inductance, capacitance, resistance
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). The Bar Graph provides an analog indication of the measured value.
The Smart Tweezers is capable of measuring voltage. In the Auto mode, it measures DC voltage up to 8 Volts. In the Trace mode, it shows an oscilloscope-like picture of AC voltage.
- Continuity/Open Test
The Smart Tweezers is designed for a continuity test. The beeper sounds when a resistance reading is below a threshold, or to indicate an open circuit.
- Durable Probes
Tweezers tips are made of gold-plated non-magnetic stainless steel.
- Ergonomic Design and Convenient Controls
Smart Tweezers features a Jog Dial button to select a menu item from the list to selected a function or to change settings. Rotate the Jog Dial button to select an item and push it down to activate the selection.
