Tips on manufacture
- Let's make finely. Especially the inside of a film case and the anode lead are good to wipe with alcohol. If there are finger marks, it will not operate correctly.
- Let's make carefully. It may short-circuit, if it makes coarsely. A noise mixes and it does not operate correctly.
Checking
- Make sure that the shield does not touch the detection part.
- Cathode and a shield line are connected.
