The sensor is in measurement

may occur during the measurement:
4.3.4.1 System supply pressure po < (pressure) threshold p1or
After the measurement starts, the sensor switches directly to an error mode if po is not at least 0.02 bar
greater than the upper threshold Pl. The display turns red. In the display, "WARN" appears underneath the
current measured value, and "P<PI" and the value for p1(e.g., "0.60") or "P<P2"and the value for
