Autometer Pro-comp Boost Gauge no longer zeroing

[92GVR4#5]

I have a Autometer pro-comp boost gauge that no longer sits in the atmospheric box for zero. Is there anyway to adjust it or have it recalibrated? Or is the gauge dumpsterbound?

Autometer Pro Comp liquid filled gauges can change readings based on altitude, temp, and barometric pressure. For this reason there is a vent screw in the top of the case. "With the vent screw in the upright position , turn the screw two turns out". The manual for mine says that this should equalize the pressure inside the case with the ambient pressure. If this doesn't fix the problem than the trash might be your best bet.

call autometer, they have been very helpful to me and they can probably fix it if you cant cheeper than to buy a new one. They stand behind there stuff pretty good
