This value can be edited using the rotary knob to highlight the High Limit. Then enter the
new value using the keypad. This will show up in the scratch pad on the lower portion of
the screen. Press the Enter key and the value for the high limit will be updated to the
value that was typed into the scratchpad.
Low Limit
The Low Limit — User Defined Minimum Pressure Limit is the same as the high limit
except it is to protect the DUT from low pressure limits.
Slew Limit
The slew limit is used by the system to assure that the slew rate is not exceeded. If the
slew rate is exceeded, the PPI will change from the control mode to the measure mode
and it will generate an error message to the operator.
Access
The test access password allows the user to protect access to PPI configuration and
programs. If the test access password is set to any number other than zero (factory
default), it is
required
before the user is allowed to change the limits, control parameters
or programs.
Note
It is recommended that the access password be recorded and filed in a
secure location.
Menu | Setup — User
The Menu | Setup | User menu is used to setup all of the user specific configurations. This
includes setting the control step size, range of bar-graph, pressure gas head, display
pressure filter, display resolution digits, and audible key click.

Gas Head Pressure Correction
The term “head height” refers to the vertical distance between the sensing element in the
device under test and the PPI’s pressure reference plane. Once the user inputs the head
height and selects air or nitrogen, the PPI automatically corrects for head pressure.
1.
The Pressure Reference Line on the PPI is defined as the bottom of the color display
where the display and the front panel join. This provides the
reference plane
against
which the device under test (DUT) pressure is measured.
