Notes 6.1 Ordering Document Contents FU101F Transmitting Tube; Detailed Specification Number: Manufacturer Code or Name; Quantity. 6.2 Notes on Use a. The insulation strength between the electrodes should be tested before using the transmitting tube. b. When the transmitting tube is stored for more than half a year, the storage warehouse is relatively humid or the insulation strength between the electrodes is low, the rated filament voltage should be added for aging. The aging time . is more than 30 minutes. During aging, the anode and the tube base must be forced to cool according to regulations.
