You'll need at least 2 different tools to cover all those models. I'm not sure about the TX.

Actually step 5 of final testing chapter of the manual does say this:
I am having a similar challenge as in I am unable to get the XTX50 to freeflow. And if I use the lever height tool, then the regulator dribbles/bubbles mildly in a bucket of water and so far adjusting the spring tension with the lever height tool as the decider has given me a 1.2+ range of cracking pressure. The gas flow from the XTX50 I get upon tapping the purge is also not as violent or furious as my c370 or the S600… Need to play with it a bit more I guess…

SP free flow will knock your teeth out. Apeks free flow pales in comparison.
Ah I get it now …

Once initiated by, "tapping purge button rapidly", a correctly tuned XTX will free flow with Venturi on max.
A correctly tuned SP C370 and S600 second stage will violently free flow simply by pressing purge button when Venturi on max.
Note, adj knob needs to turned all the way out.

The Apeks purge button excursion is quite limited. It's very variable whether a purge button tap will initiate freeflow in the XTX, especially when the reg is not at the low limit of cracking effort. One of many complaints I have about this popular reg set.
So I had to ignore the lever height tool and dial back the orifice a bit to achieve a satisfactory force in the purge flows. I am still unable to tune it in order for it to freeflow with a few rapid taps outside of water and then still pass the submerged dribble/bubble test, but I am able to get the reg to freeflow very satisfactorily on submerging in a bucket of water once the orifice and spring load was tuned to stop all dribbles. The freeflow is now violent enough to be satisfying.
So is it safe to ignore the lever height tool now and cease the endless iterations of fine-tuning it even if the No-Flow side of the tool induces gas flow? (As long as it passes the submerged bubble test)?
The other confusing thing is that while I read 1.1 on the Magnahelic while sipping on air, the water test with a measuring scale seems to measure 1.2 to 1.3” (just above the XTX logo. Edit : remeasured it correctly from the case thread/body, not from the purge button) … what could I be doing wrong here (or is it just an observational error of judgement)?
I am unable to reduce the spring load without observing bubbles …

Gas flow on "no flow" is not a safety issue as if anything according to "tool" lever is too high.
No flow on "flow" is a concern as it means lever is too low.
Likely "observational error".
1.1-1.2/1.3 is of almost zero real world meaning unless you're a machine. Neither measuring method is atomic clock accurate.
Depending how you "sip" air one read could be 1.1 and the next breath it reads 1.2
Have you read Vance Harlows Reg repair and maintenance. I'll assume not. It will help with perhaps a greater understanding.
If you've not read it/got it DM me.
