Intrinsic; Kc Calibration - Siemens SITRANS FUH1010PVDX Operating Instructions Manual

Section 5

Intrinsic

When selected, the meter uses no slope adjustment at all. Output data is still zeroed and corrected for
Reynolds number, but no slope adjustment is imposed on the meter's flow register.
Some applications may require an output adjustment to match an official external reference. The [Cali-
brate Flowrate] menu allows you to select a calibration mode. The right-hand column shows the active
calibration mode. You can select Intrinsic (factory) and Kc (Slope Correction) Calibration. Selecting either
of the external calibration modes will not eliminate the Intrinsic (factory) calibration. You can use this
menu cell to switch between Intrinsic and Kc at any time.

Kc Calibration

For most applications, the measured flow range produces a linear meter response. Therefore, the Kc
(slope correction) calibration is the preferred method since it only requires a single correction factor for
all the flow rates encountered.
NOTE: Changing the calibration can cause profound changes in a flowmeter's operating charac-
teristics. Use only the most respected flow standard to obtain a correction factor. The
percentage you enter must provide an accurate and consistent shift across the entire
flow range anticipated for the application.
