Zero point adjustment
All measuring devices are calibrated in accordance with state-of-the-art technology.
Calibration takes place under reference conditions→  100. Therefore, a zero point
adjustment in the field is generally not required.
Experience shows that zero point adjustment is advisable only in special cases:
• To achieve maximum measuring accuracy even with low flow rates.
• Under extreme process or operating conditions (e.g. very high process temperatures or
very high-viscosity fluids).
