Hello

Sorry if this is a silly question, but I can't seem to find anything online about it... The IN-17 datasheet says that before soldering it's suggested to "train" the nixie with a common current source to each cathode. What is this supposed to accomplish?

Thank you,

You must be "loading" neon tube before use.
You need loading tube by current 1.5-2 ma for 2 minutes, because some
microgram mercury need to be vaporize from cathodes.

Just the IN-17, or do all IN tubes need this? I've only intentionally done it for barograph tubes.
