DESCRIPTION
The 311/RT1/717S Primary Phase Angle Standard System is composed of three separate interconnected units mounted in an attractive sturdy cabinet. The 311 is the Phase Angle Standard. The RT-1 is a precision 7-digit ratio transformer. The 717 is a tuned null detector. The system operates in the frequency range of 30Hz to 10kHz. This instrument can generate a precision phase shift and can perform precision phase angle measurements. The phase shifters resolution is better than 12 µ° for any phase setting. The max input voltage (500Hz to 2kHz) is 125 Vrms.
