For no apparent reason, my gauge shows extreme levels of vacuum, pulling the oil to the far right side of the gauge. If I pull the hose off the stack, it returns to zero and then works for awhile and then goes to the far right side again the next day or week.
Anybody else have this problem?

Here's what I would check for -
Guess #1:
How about a super-strong draft on an a windy day and you don't have the baro damper adjusted properly? Or maybe the baro has a lot of ash buildup? It could even be a severe down-draft on the windy day.
Guess #2:
Something blocking the 'open' connection to the manumeter.
Guess #3:

Is the high port open? I put the hose on mine just to keep dust out. They are very sensitive so it doesn't take much to goof them. They also are not designed for continuous use, just a quick reading as they required to be zeroed before each reading. No doubt a gust (or many, as it is probably accumulative over time) gets it up there, why it doesn't come down is unclear but the high port being blocked would be the suspect.Bratkinson wrote:Guess #2:

Yaa, something's plugged someplace.
I have mine hooked up continuously. I have checked it now & then it it stays calibrated for me.

Definitely not a wind gust. One time I pulled the hose off and nothing happened. Dust could be the answer cuz I have the port open. I've been using it continuously since January and it's only been the last few weeks for the problem.
