The specifications are only valid if the positive pressure is
applied at the positive pressure connection.
• 1.2 % of measuring range, additional ±0.3 Pa intrinsic error

At 25 °C. A stabilization period of approx. 30 min must be taken into account
upon commissioning the instrument.

Measuring uncertainty in accordance with GUM: ±1.2 % of measuring range
final value ±0.3 Pa.
GUM (Guide to the Expression of Uncertainty in Measurement): ISO guideline for determining the
measuring uncertainty in order to render global measurement results comparable.
The following uncertainties are used during the inquiry:
• Hysteresis
• Linearity
• Reproducibility
• Long-term stability
• Adjustment area/factory calibration
• Test location
