    6.3. S etting the Unit of Pressure and position of Decimal Pointput 2 5 B The decimal point is automatically shifted The decimal point position may differ from the table above when the ✔ Note measurement mode is restored. The reason is that when the measured pressure is below 1/10 of the full scale value of the sensor head, the position of the decimal point is automatically shifted by one digit to enhance the resolution of the measurement value.
