CT Filter Pack Option (33551)
7.1 Introduction
The CT Filter Pack (33551) provides a non-invasive way to make independent tests of the internal voltage
divider of a CT system -- and a convenient and safe way to check tube voltage.
The actual kV waveform of the CT machine can be displayed on a storage oscilloscope. If the CT
machine is a DC (continuous scan) unit, the proportional voltage can be read on a DMM.
These applications are made possible with the CT Filter Pack (33551) in conjunction with the Model
35080B kVp Divider.
