• Up Single Arrow and Down Single Arrow – Increases or decreases the gas pressure in 0.1 psi
increments, respectively.
• Up Double Arrows and Down Double Arrows – Increases or decreases the gas pressure in
2.0 psi increments, respectively.
• Input – Allows you to manually specify a pressure value in real time.
• Pressure Scale (High, Middle, Low) – Changes the pressure scale displayed on the
y
axis.
• Right Arrow and Left Arrow – Increases or decreases the profile time displayed on the
x
axis.
• Run – Executes the pressure profile currently on the screen.
• Stop with PSI – Stops the time clock of the profile, but maintains the pressure at the then-
current level. Useful if you want to extend the profile time scale an indefinite amount.
• Stop without PSI – Stops the time clock of the profile and shuts off the gas pressure.
• Open Manifold – Raises the manifold to the Current Consumable Height.
• Close Manifold – Lowers the manifold to seal on the top of the consumable stack.
• Full Open Manifold – Raises the manifold to the uppermost position.
• Save and Save As – Saves the current profile with the existing name or a new name,
respectively.
• Back – Returns to the most recently opened screen.

Function details:
• COM Port – Selects the communication (COM) port, which the Microsoft Surface Pro tablet
uses to communicate with the internal control board of the Otto SPEcialist.
• Press Steps – Determines the additional number of stepper motor steps that the manifold will
travel downward once the consumable stack is detected, and determines how hard the
manifold is pressed against the consumable stack.
