Arrrgh!

I am trying to run some H2 standard on-offs with our Delta plus XP (I'm 
running water dD with the Gas Bench). Alas, I seem to have cup 5 (mass 3) 
maxed out at 50 mV and I can't seem to un-max it. I've tried shutting off 
the source, restarting the computer, starting a sequence, peak centering, 
and jumping to different masses. It's just stuck at 50 mV. I didn't just 
lose my cup, did I?

Does anyone have a quick and painless solution to this wee problem?

Thanks,

~Penny
