## Questions & Answers

**Q: can the units be switched from psi to "WC?**
A: Yes I used mine for measuring LP gas pressures.

**Q: What is the thread size of the barb metal connector - 1/4 in. or 3/8 in?**
A: The hose Barbs appears to be molded into the housing, for the supplied 1/8" ID dia hose.

**Q: why are there 2 connector ports?**
A: Second port is for measuring differential pressure, not needed if only reading pressure, and there is a positive and negative.

**Q: Why does it read -.018"H2O without even taking the measurement? That would be quite an error.**
A: Because it hasn’t been “zero’d” yet.
