1.4 Calculated values
Pressure units – conversion to hPa, Pa, mbar, mm·H20, PSI in accordance
with generally applicable conversion rules
Temperature units – conversion from °C to °F in accordance with generally
applicable conversion rules
Flow rates – Prandtl measurements displayed in m/s, automatic continuous
density correction based on temperature signal
Range: 0.0–120.0 m/s
Volumes – Boyle's law with T = constant, 0.1–6000 litres
Statistical characteristics – minimum, average, maximum of all measured
and calculated values in the respective measurement units
Date and time – output to measurement records
4-PA-test - Calculation and printout of a time-graph for the documentation of
