The video tubes should be stored under the conditions of ambient condensation of -35~～50℃, relative condensation of no more than 80%, and no corrosive gas.
If the video tube is stored for more than three months, the hot wire should be energized for 30 minutes before use. The video tubes that have been inspected and stored in the warehouse of the manufacturer should be inspected for all items of QC-1 at the end of storage.
6 Explanation
6.1 Contents of order documents
a. Number and name of the video tube specification
b. Video tube model and name: SF-1213 video tube; c. Detailed specification number and name;
d. Manufacturer name;
e. Quantity.
6.2 Precautions for use
a. When the video tube is operated with excessively high compensation current, the photoconductive target will be damaged and the video tube life will be shortened. When adjusting the video tube target voltage, the peak dark current must not exceed 200nA: b. The cathode preheating time is at least 1 minute:
c. The external magnetic field should be shielded:
