The fact that the last page shows a Mecha that's named Arleo and becomes Yuuta's later on, makes me think the correct translation of the last portion of dialogue would be more akin to:
S2
That measuring device can measure up to 100k.
S1
No, that's not possible, no way.
And even if such a Rudia Value was possible, there isn't a Mecha that needs a Rudia Value that high!
Que the shot of Arleo, a Mecha that is repeatedly commented as being unique, special, weird, etc. and didn't even turn on when a triple highlander 30k-39,999 Rudia Value user tried to start it.
