What part of the fill needle is correct 🤔

[Redick]

When using the gauge to fill your tank/pcp which end of the needle do you use? For example, if filling to 200bar would you stop at the beginning of the needle on 200 or the back, which is right?

It doesn't matter. Fill to where your shot curve starts. If you have a reg then just stop a little before or after. No big difference. No safety concern

Thanks!

Most likely neither side of the needle is correct. The gauges are most often off by 10 to 20bar they are good for an approximate pressure. My FX arrived with a gauge that was 40+ bar off.

Always trust the highest reading you get. That said there are sufficient safety margins in the equipment to preclude the necessity of being paranoid. You have two gauges and one reads higher than the other. Trust the higher one. You have some sort of indicator that you can read two ways. Read it the higher way. This is the common sense approach to safety.

I usually go by the oil filled gauge on my fill tank..
