Common problems and solutions for hollow cathode lamps

Reason: There is impurity gas inside the lamp.

Solution: Place the light in10-20mAReverse discharge under current for a few minutes to half an hour, if ineffective, then80-120mAReverse discharge under current to activate the suction agent.

2.Problem: The shielding tube emits light, causing the emission to weaken and become unstable.

Reason: The needle shaped crystals or flakes of sputtered gold chips detach, causing the cathode to be connected to the shielding tube.

Solution: Vibration the lamp housing to disconnect the connection.

3.Problem: Anode flashing.

Reason: Uneven discharge on the anode surface.

Solution: Generally, it does not affect usage. If there is an impact, it can be addressed in10-20mAReverse discharge for half an hour.

4.Problem: The outer and rear sides of the cathode emit light. Slightly weaken the transmission line.

Reason: The distance between the shielding tube and the cathode is too large, or there may be impurities in the gas.

Solution: The launch is stable and can still be used. If necessary, press1Reverse processing.

5.Spark like discharge with jumping occurs inside the cathode, and there is no measurement line emission. It cannot be used until normal discharge is restored.

Reason: There are oxides or impurity gases on the surface of the cathode.

Solution: In30-50mAReverse discharge or increase the current stabilizing resistor in series with the lamp2-10A thousand euros.
