Yes.

Sorry, I'm still confused. If I'm using a DynoJet 248 with RECENTLY
calibrated load control option....It cannot hold a load/speed site for
1 second or longer?

Of course; sorry, that wasn't my point.

Can someone recommend a 4gas analyzer?? I'm trying to figure out if I can
make use of one on my inertial. I don't understand why Adam says It
can't happen on an inertial -- eventhough It has the load control
option.....maybe I don't understand this option properly? Thanks.
