will appear and the cursor will be pointed to the offending area of the setup screen. Once the setup is correct,
the following screen will appear:
Manual Cal: choose this option to perform free style calibration checks by 1) applying a pressure of interest
or 2) by selecting a simulation value manually. The user creates this calibration documentation as he goes.
Save as many free-style points as needed to complete the calibration documentation session. Selecting
Manual Cal for a pressure calibration will cause one of the following displays to appear.

Apply the desired input signal to the MFT and device under test, wait for the value to stabilize and press the
Save soft key to save the displayed data to memory. The MFT will provide “Saving Data Point…” feedback
on the display, show “1 Points Saved,” and prepare to accept the next point.
Apply the next desired input signal and press the Save soft key when satisfied with the input signal. Repeat
as needed to complete the As Found points. Press the Done soft key to end the As Found portion of the
documenting session.
If the MFT needs to provide simulation of an input signal to the device under test, the Meas / Sim line will
have been pointed to a simulation module (such as the RIO4000, TIO0110 or VMA0055 modules). In these
cases, starting the Manual Calibration will prompt the user to Enter Output Value using the numeric entry
methods on the MFT. Once the first point is saved to memory, the MFT will ask if the user wants to simulate
another point. Selecting Yes continues the Manual Calibration while selecting No ends the session.
Create (Manual) Procedure: chose this option to develop a structured calibration procedure through the
MFT user interface. Once completed, the procedure will either 1) prompt the user with a pressure value to
apply or 2) start a simulation procedure using the simulation module selected. The Create Procedure set
up screen is shown below. To change values simply move the cursor to the desired menu option and press
the Select soft key. Use the MFT’s user interface to change or input the values desired.
