Electronic Measurement Circuits

System

Basic equipment for the construction and metrological examination of assemblies of electronic voltmeters. Topics include the frequency-compensated input divider with protective circuit, the high-impedance input amplifier, measuring amplifiers for DC and AC voltage and precision rectifiers.

Function

The series of exercises deals with the principles of measuring device circuits.

The exercises consist of

• the measurement setup and execution,
• mathematical evaluation,
• the graphical representation

Equipment for student experiments and/or teacher demonstrations with non-hazardous low voltage. The experiments are carried out using a manual in printed or electronic form.

Target group

Vocational training in industry and students specialising in automation technology and mechatronics. The course offers the basics of electrical measurement technology.

Topics

• AC voltage measurement with moving coil movement
• Voltage measurement range extension
• Current measurement range extension
• Impedance converter with FET
• Impedance converter with operational amplifier
• Basics of digital measurement
