Low pressure manometer readings
Bud9051:
Jason and others,
I want to be able to measure zero through 5 pascals or so with a reasonable degree of consistency. My DG-700 just doesn't want to average down that well. I would rate my skills with a manometer as needing advice, but I'm wondering if there are other meters better suited for the task.
These would be stack pressure reading from inside to outside a house.

I only used the DG700 during training, but it always seemed to be pretty accurate & easily handled those measurments - so I am curious what the averaging issue is. When was the last time you checked the calibration on yours?
David Meiland:
Bud, check the manual and figure out how to adjust for longer averaging... go for 10 seconds or so and it smooths out the readings nicely.
Bud9051:
Calibration is fine, but I'm just looking for a really stable number.
David, read the manual right :). Well it worked. I was doing everything correct, but when I went over the process I realized I was overlooking exactly what I need, baseline averaging. We can allow the baseline to average over a much longer time. The 10 seconds wasn't enough, but a full minute and my number settles down to plus or minus 0.05. And in actuality, I can estimate it even a bit closer. Already tried it and it looks good.
Jason, I would still like to hear if you have a meter that can do this a little better as I would like to have a second meter anyway.
Thanks,
Bud

Bud,
When you see the averaging it effects the baseline and it effects the actual readings.
John :)
