10.9 Head Pressure Correction
The correction is accessed from the calibration menu. Four parameters may be set to reflect condi-
tions at the operator’s site. Press either [English] or [Metric] units for entering head pressure correction
information into the CPC 6000. See Figure 10.9A.
Head correction parameters are stored separately for each channel.
Height: Enter the difference in height between the center of the measure/control port of the CPC 6000
and the reference level of the Device Under Test (DUT). If the reference level of the DUT is lower than
the center of the measure/control port of the CPC 6000, enter a positive height. If it is higher, enter a
negative height. See Figure 10.9B.

Gas Density: If nitrogen (N2) or dry air are being used as a pressure media, press the appropriate
selection. If another gas is being used, enter the density for the gas at standard pressure and tempera-
ture in either lb/cubic foot (english) or kg/liter (metric) units. See Figure 10.9C.
Gas Temperature: Enter the average gas temperature in degrees F or C. If unsure of the gas temper-
ature, use 68 F. See Figure 10.9D.
