🔍 Key Concepts

• Offset vs. span error when comparing a pressure gage to a test standard • What a set point adjustment changes in an instrument’s indication • What a proportional band (range) adjustment changes in an instrument’s indication

💭 Think About

• Look at the difference between true pressure and indicated pressure at each test point. Is that difference the same or does it change with pressure? • If ALL points are off by about the same amount, which adjustment usually fixes that kind of error? • If the error gets bigger or smaller as pressure increases, which adjustment usually fixes the slope/range of the indication?

✅ Before You Answer

• Calculate the error at each point: Indicated – True, for all four readings • Decide if this error is constant (same offset) or changing with pressure (span/slope issue) • Match a constant error to the proper adjustment and a changing error to the other adjustment before choosing your answer
