Life test the life test was developed to tell servicemen how much useful life still remains in a tube being tested. Therefore tubes can be checked and selected for balance between sections.
Each section of a dual section tube is checked separately. This test will reveal as little as 2 or 3 micro amperes of current in the grid circuit. Any tubes that are stated nos are assumed only based off the condition of the tube and or test results. But if the tube under test has a depleted space charge, a large drop will occur in the meter reading indicating that a replacement is warranted.
The reading on the meter will drop very little or may even rise slightly under the reduced heater voltage conditions if the tube has sufficient reserve to continue to operate normally. Tube types tested in the switch are tested in a new DNA quick emission circuit.
A tube may test. This is convenient for selecting dual section tubes to be used in push pull circuits. Some tubes such as diodes are checked for emission only, since this test is usually sufficient.
On the gm test but the life test will detect whether or not it is in the process of losing its gm. Each tube is automatically checked for shorts and leakage up to 1 mega ohm.
A drop of 25 of the normal meter reading indicates the tube is reaching the end of its useful life. If the meter reading does not drop, the tube is in excellent condition.
These tests are made between the various elements of the tube and furthermore this test is made before the gm measurement. Gas, grid emission, or even obscure grid cathode leakage are all disclosed by an exceptionally sensitive grid current check. Provides accurate results because it checks most tubes for their dynamic mutual conductance gm in a true trans conductance bridge.
