The jog keypad
Application: Fine adjustment of the pressure value to reach a cardinal value on a pressure gauge or similar device under test.
The step keypad
Application: Calibration of incremental user defined pressure points or percent of full span of the device under test.
The pressure set point can be changed using one of three input modes
The numeric keypad
Application: Direct input of set point value.
Operation
The desired pressure set point value is entered using the numeric
keypad and then acknowledged by pressing the check mark key.
In control mode the controller will regulate the output pressure to
the entered value.
Operation
Each step on the step keypad can indicate user defined pressure
values or percent of span values for the device under test. For
example: the step keypad shown to the left is set for 10% steps
going from 0% to 100%. These steps are a percent of the user
defined device under test full span. In control mode, when a step
is touched, the controller will regulate the output to the associ-
ated set point.
Operation
The triangles on the Jog keypad have values which correspond
to the 3 last digits of the pressure reading and are used to incre-
ment the set point. Triangles pointing up will increase the value
and those pointing down will decrease it. The smallest triangle
increments the least significant digit by one, the medium size
triangle increments the least significant digit by ten and The large
triangle increments the least significant digit by one hundred. The
values will change accordingly if the resolution of the indication
is changed.

The user defined jog keypad
Application: User defined quick pressure adjustment.
Increase by user defined amount.
User defined amount key.
Decrease by user defined amount.
Operation
Pressing the “User Defined Amount” key will open a numeric
entry screen where a user defined amount can be entered. This
value will be shown in the key indication. Pressing the triangles
will increase or decrease the set point by this value.
