Automated Pressure Calibrator
CPC 6000
Mensor/WIKA Operating Instructions - CPC 6000 95
For a gauge CPC 6000, this automatic function will:
1. Vent the system.
2. Adjust the zero offset of each turndown that can measure the vented pressure so the turndown’s
output is equal to zero.
The autozero function re-zeros sensors without storing the zero offsets through
power cycling.
10.8.3 1-Point Calibration
A one-point calibration adjusts only the offset of the active turndown. From the unlocked calibration
data screen, press the [1 Point Calibration] key shown in Figure 10.8.3A. The ‘1 Point Cal’ window
shown in Figure 10.8.3B will appear. This window shows the maximum and minimum acceptable
values and the current reading. The [?] key pops up a help dialog with instructions on how to use this
screen. Enter the current known pressure in the ‘Desired Reading’ data window. Values entered that
are outside of the displayed Maximum/Minimum limits will not be accepted. When the desired reading
is displayed in the data window press the [OK] key and the offset will be stored. The [Cancel] key will
exit this window and not make any adjustments to the calibration of the active turndown.
