The other prob is that my Mater seems to want to have a .3 or .4 deadband

But I have no idea of the accuracy of the gauge.
Well, that should be accurate enough.... could be the gauge and/or pstat.

That deadband is not too good, lots of bad Mater pstats threads lately as well.

(P.S. Junior is no more?)

I took it out (Mater) and put it back and deadband is more like .25 - basically normal for a Mater. Certainly good enough for me unless I get bored at some point and put in a CEME with adj deadband or something else that's inexpensive. But this is just fine.

I was hoping if I read the temp I would know the pressure but I guess not really.

gauge 1.2-1.45bar yields 240-245F range
gauge 1.0 -1.25Bar yields 237.5-241.5 range

I was hoping to figure if the gauge was high or low and by how much. The tables don't seem to match what I read others are getting. Or maybe the gauges are just inaccurate...



Yeah, someone bought the Jr. Too big for me. Too much warmup time for me. Very nice machine, though! Priceless experience playing with it! So I grabbed Cliff's Tea. Also a very nice machine, and much better suited for my purposes!
