Ambient temperature deviations during pressure gauge calibration can lead to significant errors. For example, a 1.5%-grade gauge tested at 5°C may fail without proper compensation5.

• Compensation Formula:
  $\mathrm{\Delta }=\pm (\delta +0.04\mathrm{\%}\times \mathrm{\mid }{t}_2-t_1\mathrm{\mid })$
  Where $\delta$ is the baseline error and $t_2$ is the ambient temperature5.

• Best Practices:

• Use reference sensors to adjust readings dynamically (LNE-ENSAM)1.

• Follow JJF (Su) 96-2024 for steam sterilizer calibration, which mandates ±0.5°C uniformity4.
