  • Page 7: Safety Specification

    1. Safety Specification This instrument is designed according to EN61010-1 Specification. The main pur- pose of this Specification is to ensure that the instrument will be used in the labor- atory or the factory safely; it is not suitable for outdoor applications, especially the moistened or dusty locations.
  • Page 8 The instrument will operate normally upon starting the power. To achieve the specified accuracy, it is suggested warming up the instrument for over 15 minutes 1.6 External control unit This unit is able to execute the external control. For this purpose, please ensure that the operator is not touching the signal output end and the Test Piece to avoid causing hazard.

  • Page 82: Resistance (R) And Conductance (G)

    ◆ Resistance (R) and Conductance (G) The resistance is a measure of the difficulty to pass an electric current through that conductor. The SI unit of resistance is the “ohm” (Ω). The inverse quantity is electrical conductance, and this is the ease with which an electric current passes through a circuit.

  • Page 83: Capacitance (C)

    ◆ Capacitance (C) Capacitance (denoted by the letter C) is the ability of a body to store an elec- trical charge at a given potential difference between its plates. The SI unit of capacitance is the farad (symbol: F). Measure Type：Series mode→Cs / Parallel mode→Cp Relevant Equations：...

  • Page 84: Inductance (L)

    ◆ Inductance (L) Inductance is the property of an electrical conductor by which a change in current through it induces an electromotive force (EMF) in both the conductor itself and in any nearby conductors by mutual inductance. In the SI system, the measurement unit for inductance is the Henry (with the unit symbol H).

  • Page 85: Reactance (X) And Susceptance (B)

    ◆ Reactance (X) and Susceptance (B) In AC circuit analysis, reactance is represented by the capital letter “X” which is the imaginary a part of complex impedance. Reactance is the opposition of a circuit element to a change in the current or voltage, due to that element's inductance or capacitance which is similar to the opposition of resistance to current in a DC circuit.

    ◆ Impedance (Z) and Admittance (Y) The impedance covers oppositions in AC circuits in- cluding resistance, inductance, and capacitance and is measured in units of Ohm (Ω). In electrical engineering, admittance covers both conductance and suscep- tance and is the reciprocal of impedance. It is measured in units of Siemens (S).

    ◆ Quality factor (Q) and Dissipation factor (D) The quality factor measures energies consumed by relative frequency. In general, the better a circuit's quality factor the better its selectivity. The dissipation factor is the reciprocal of quality factor. It is the signal angle loss by a capacitor (or inductor) and acting frequency at a fixed temperature.
