Impedance Task (IMP)
Task of the QC STANDARD Software and Optional Module for the R&D System
Features and Benefits
- Measurement module for the Klippel Analyzer System
- Optimized for quality control applications, such as end-of-line testing
- Included in the Klippel QC Standard Software package
- Stimulus: fast multi-tone or chirp based
- Inductance models: Wright, Leach, LR-2
- Electrical signal (voltage, current) analysis providing
The Impedance Task (IMP) identifies the lumped parameters of the equivalent circuit of the transducer, including Thiele/Small, creep and lossy inductance parameters. It complies with IEC standards 60268-5 and 60268-22. A multi-tone stimulus is used to measure the voltage and current using the measurement hardware Klippel Analyzer KA3 (QC Card, Speaker Card) or Production Analyzer. To ensure accurate measurement in the small signal domain, distortion in current and voltage are measured and checked against admissible limits.
Options operate as plug-ins and extend the functionality of this task.
No additional test time is required, all options use or modify the excitation of this task.
