7.8.2 SETUP Control
Configuration of parameters associated with setting limits and adjusting parameters used
to control pressure are configured in the
MAIN -> [SETUP] -> [CONTROL] menu shown in
"Figure - SETUP Control".
Maximum and Minimum Control Limits: The [DATA ENTRY] keys next to the [MINIMUM]
and
[MAXIMUM] labels in "Figure - SETUP Control" allow the operator to select any
range within the full scale range of the internal sensor. This is the "user defined range". For
example: if the CPC3000 has a 0-5 bar internal sensor, the user can define a range of 0-4
bar. When the user defined range is changed, a corresponding change occurs in the STEP
menu so that the percent STEP will equal the corresponding value within the user defined
range. For example: the 80 % value of a 0-4 bar user defined range will be 3.2 bar but for a
user defined range of 0-2 the 80 % value equals 1.6 bar.
The user defined range can be
set to the same range as the pressure device being tested. This useful when there is
a test that requires calibration at intervals equal to a percentage of the range. Each
individual step can also be changed by pressing the
[STEP] key and entering a
new value.
Bar or %FS: The [SELECTED UNITS] and [%FS] keys switch the
STEP keypad display in the main menu and on the SETUP screen from the user selected
units to percent of the full scale of the user defined range. The values when shown in the
[SELECTED UNITS] mode correspond to the values in the [%FS] mode. For example, in


"Figure - PSI Mode", the [PSI] key is pressed
and the value shown in the 100 % step is
4.0000 corresponding to the maximum limit
chosen in this same screen.
Individual steps in %FS or selected units
mode can be included or excluded from the
step menu by changing the
[Check Box]
next to the STEP.
