OPERATION
PPCK+ uses self diagnostics to determine when to run the TPC configuration
routine in dynamic control mode. Therefore, it is not normally necessary to run
the configuration routine separately.
Running the Config routine may cause the set pressure to increase or decrease
by up to 1.4 MPa (200 psi).
The dynamic control mode volume determination routine may be run at any
pressure greater than 1 MPa (150 psi). Dynamic pressure control mode must
be active.
To run the volume determination routine,
first set a pressure above 1 MPa (150 psi).
Then press
[SPECIAL] and select
<4Internal> , <1Config> . The display is:
Selecting <1Yes> causes the volume determination routine to run. While the
routine is running, <Running config…> flashes on the bottom line of the
PPCK+ display. Completing the routine may take up to 2.5 minutes and cause
the pressure to change by 0.7 to 1.4 kPa (100 to 200 psi).
When the volume determination is complete
the display is:
Select <1Yes> to activate the new volume determination. Select <2No> to retain
the old volume determination and return to the main run screen.
The volume configuration routine cannot be run under 1 MPa (1 000 psi). An error
message is displayed if the volume configuration routine is initialized at a
pressure under 1 MPa (150 psi).

PURPOSE
To calibrate the PPCK+ reference pressure transducer (RPT) and adjust the
on-board barometer. This function is considered part of PPCK+ maintenance
and is therefore covered in the maintenance section of this manual (see
Section 5.2).
