    SIGLENT Example Thermocouple setting measurement Thermocouple is a common temperature sensor. Type, voltage and cold-side temperature are required for thermocouple measurement. The instrument can measure temperature of HI and LO terminals (cold-side), and calculate absolute temperature of hot-side. Besides, only the relationship between thermocouple voltage and cold-side temperature is need to be input according thermocouple type when you set the thermocouple sensor.

  • Page 103: Chapter 4 Measurement Tutorial

    SIGLENT Chapter 4 Measurement Tutorial True RMS AC Measurement The AC measurement of the Multimeter has true RMS response. The power dissipated in a resistor within a time is proportional to the square of the measured true RMS voltage, independent of wave shape. The instrument can accurately measure true RMS voltage or current, as long as the wave shape contains negligible energy above the effective bandwidth.

  • Page 104: Crest Factor Errors (Non-Sinusoidal Inputs)

    SIGLENT Crest Factor Errors (non-sinusoidal inputs) A common misconception is that "since an ac Multimeter is true RMS, its sine wave accuracy specifications apply to all waveforms." Actually, the shape of the input signal can dramatically affect measurement accuracy. A common way to describe signal wave shapes is “crest factor”.

  • Page 105: Loading Errors (Ac Voltage)

    SIGLENT Loading Errors (AC Voltage) In the AC Voltage function, the input of SDM3055 appears as a 1MΩ resistance in parallel with 100pF of capacitance. The test lead that you use to connect signals to the Multimeter will also add additional capacitance and loading.

  • Page 106: Application Of The Analog Filter

    SIGLENT Application of the Analog Filter The analog filter of the Multimeter can be used to reduce the influence of the AC component in DC measurement. Generally the filter may not be required, but sometimes it can improve the DC measurement. For example, if the measured DC electrical source has a big AC ripple, the analog filter can reduce the influence.
