Radio Influence Voltage (RIV) calibrator KAL 9531 is a successor to the popular Tettex 9220a. However, KAL 9531 exceed functions of its predecessor and present competition and became a proud market unique device combining two RIV measurement standards – NEMA and CISPR – into a single device.

It is compact, easy to use and has the solid long battery operation capability. KAL 9531 offers a unique possibility to conduct backward compatible measurements with former valid and broadly used NEMA 107-1987 standard (Stoddart RIV meter) but also to follow currently valid CISPR 18-2 standard used for Electromagnetic Compatibility (EMC) measurements.

Its unique high-end design ensures high quality output sinus signal within a wide frequency range providing coverage of requirements for Factory Acceptance Test (FAT) measurements.

The RIV calibrator is easily controlled by two large buttons. Voltage and frequency values are displayed on a large display together with battery status and test standard selection.

Advantages
• All in one: One single device allows calibration according the latest CISPR 18-2 as well as backwards compatible with NEMA (Stoddart).
• Optimized for routine tests and FAT/SAT.
• Ease of use: Large display provides complete overview about the selected settings (applied standard, voltage and frequency). No need to scroll thru any complicated menu.
• Robustness and compactness: Light weight, solid casing and decent battery operation.

Applications

• Power and distribution transformers
• Instrument transformers
• Switchgears (MV/HV/GIS)
• Surge arresters
• Bushings
• Cable accessories
• Power capacitors
• Components testing
