  • Page 5: Getting Started

    GETTING STARTED This section summarizes basic operation of Smart Tweezers. In the section: OVERVIEW : Overview of the device controls. POWER-ON: Describes the power-on and power-off sequence, the warm-up time, and default conditions. DISPLAY: Discusses the display format and messages that may appear while using the device. MENU STRUCTURE: Covers menu structure, system settings and features.
  • Page 6 HOW IT WORKS ST evaluates impedance of a component by measuring the voltage across the component and current through it. The complex ratio of voltage to current is equal to the complex impedance. The unit’s processor calculates various parameters that are displayed i.e. R, C or L. VOLTAGE SIGNAL TO ADC CURRENT SIGNAL...

    Certain devices require a specific test voltage, such as Z5U ceramic capacitors (test voltage = 0.5 Vrms for 25V parts and 1.0V for < 16V parts). Note: Use the largest voltage possible for the best SNR and accuracy. CONTROLS The Navigation Control The navigation switch is used to select a function or to change a setting of Smart Tweezers.

  • Page 8: Power On

    UP – change test ranges DOWN – change test signal levels LEFT/RIGHT – change measurement modes POWER ON POWER-ON - To turn the Smart Tweezers ON, press the navigation switch twice. Note: Once powered on, the unit will perform the last selected function. POWER-OFF - ST6 powers off automatically if neither a measurement is performed nor the navigation control is operated for approximately 30 seconds (default value).
  • Page 9 PRIMARY DISPLAY: The Primary Display is located in the middle of the screen and uses the largest font. It shows the dominant impedance parameter reading typically with 5 digits displayed. SECONDARY DISPLAY: The Secondary Display is located just above the Primary Display. It shows the minor impedance parameter reading. TEST PARAMETERS: The Test Parameters area is at the top of the screen and provides information about current test conditions such as Test Frequency, Range, Test Signal level, Test Model.

    C+R MODE: Capacitance is shown on the Primary Display and the parallel resistance R, is shown on the Secondary Display. The units of capacitance are pF, nF, or µF. Resistance units are Ω or kΩ. Parallel (C < 500 pF) or serial (C > 500 pF) equivalent circuit diagram is used. C+D MODE: Capacitance is shown on the Primary Display and dissipation factor D on the Secondary Display.

    MEASUREMENT FEATURES This section describes specific ST functions and settings. Measuring resistance Covers resistance measurements. Measuring capacitance Covers capacitance measurements. Measuring inductance Covers inductance measurements. Testing diodes Describes testing general-purpose diodes. MEASURING SMALL RESISTANCE There is some small resistance offset due to the resistance of the tweezer tips, and resistance of the contacts between the tips and DUT.

  • Page 22: Measuring Inductance

    Optimal test frequency 10 kHz <10000pF 1 kHz 10001pF- 10μF There is some small capacitance offset due to capacitance of the tips. The offset depends on the distance between the tips (i.e. measured component size). The offset value should be used in calculation of the actual capacitance. Table below shows typical offset values for different component sizes: Offset, pF Component size...
