Varian Multi-Guage L9066301 L9066-301 Inverted Magnetron Board (Pulled from working Varian Multigauge Controller)The Multi-Gauge Inverted Magnetron Board (Part No. L9066301) operates the InvertedMagnetron Gauge (IMG) with cable lengths of up to 100 feet. Its operating voltage is +3 kVand its nominal sensitivity is 2.7 A/Torr. The use of software linearization and dynamicpower modulation allow a useful range of 1 x 10−3 to 1 x 10−11 Torr. The IMG board can be installed in any one of the five slots in the Multi-Gauge unit,however, since it is a high-profile board,VacuumTechnologies recommends that it be put into one of the three right-hand slots (as viewed from the front of the unit) for maximum flexibility.
