Edit Curve
Use the Edit Curve menu to program the flow curve, which the computer uses to calculate the flow rate using the K-factor
(counts per unit measured) and frequency/viscosity The calculation uses the frequency card You can program a curve for
each channel

and enter the numeric value to enter/change data The computer reads from the lowest to highest K-factor
and frequency/viscosity, so each point of the curve should be entered from lowest to highest The screen shows SET on the
left, indicating that data is being entered

Frq Cut Off
When below this value of frequency, then FRQ = 0 0
Vol Cut Off
When below this value of volume flow, then Vol Flow = 0 0
Mass Cut Off
When below this value of mass flow, then Mass Flow = 0 0
Vol Factor
Multiply Volume flow rate by this factor (for special applications)
Mass Factor
Multiply Mass flow rate by this factor (for changing to pounds 8 32778)
