] Highlight „d-Align.“. This function automatically determines the
measured value difference between the channels used in the formula and takes
it as Offset.
Assure that both sensors are exposed to the same measured value (e.g. the
same pressure). Then press [Enter] to align the sensors.
Press [ C ].
Available formulas
UNDEF
no calculation will be executed
C1–C2
difference of the measured values from channel 1 and 2 (e.g. delta-P)
C1+C2
sum of the measured values from channels 1 and 2
dC1/dT
calculated the fi rst differentiation of the measured values from channel 1
dC3/dT
calculated the fi rst differentiation of the measured values from channel 3
C1*C3/600
calculated the hydraulic capacity; the pressure p in bar must be measured
on channel 1 and the volume fl ow rate Q in l/min on channel 3
