Figure 10.9-A – Linearization Application Data Matrix
The Linearization Application automatically populates the screen with equidistant increments from
the low to high pressure corresponding to the range of the transducer selected. These values can be
changed to reflect the values generated by the reference standard and the corresponding readings taken
from the CPC3050. Each value from the reference standard can be entered under the reference column,
corresponding Upscale and Downscale readings from the instrument can be entered in the “Actual” col-
umn or “Upscale” and “Downscale” columns. To enter a value simply press the number and a key pad will
appear (see Figure 10.9-B) where the number can be entered. Press the check mark [
] to accept
each value. With upscale and downscale on, the “Average” column automatically averages the upscale
and downscale values.
Figure 10.9-B – Linearization Values
Figure 10.9-B shows some typical values that might be seen in a linearization calibration. In the bottom
right hand corner of this screen is the Graph Icon [
] that, when pressed, reveals a Linearization Er-
ror Graph that gives a visual representation of the errors associated with the values entered in the Linear-
ization screen.
When actual pressure is selected, the reading is able to be pressed on the touchscreen. Reference
pressure values must be entered before actual pressure values. When entering a reference pressure, the
corresonding actual pressure value(s) will be updated either to 1.) the current reading within limits or 2.)
match the entered reference pressure. When an actual pressure value is slected the main reading will be
active to easily enter the current reading.
