LIFE TEST
The quality of all production is monitored by the random
selection of tubes which are then life-tested under the above
Test Conditions. If the tube is to be operated under conditions
other than those specified herein, E2V Technologies should be
consulted to verify that the life of the magnetron will not be
impaired.
