Alternative Numeric Entry: When the MFT is in a mode expecting numeric entry from the user, a coded
numeric entry system becomes operational. Four of the main keypad buttons (see below) become active for
direct number entry. For example, use this feature to enter simulation values for VMA0055, TIO0110, or
RIO4000 modules, entering URV or LRV during HART communications, or setting the internal clock. Use the Å
and Æ soft keys to move the cursor to the desired location. For a number 3, press the “S1 Units” key three
times. For an 8, press the “S3 Units” key twice.
MEASURE MODE
After the MFT performs its power up diagnostics and displays the model number and sensor data, it defaults to the
Measure Mode. The word Measure appears on the upper left of the display, confirming this mode is active. The soft
key definitions in this mode are directed toward measurement and information functions.
Header-line Symbol Key (see location at right)
heart symbol indicates active HART communication
u up arrow indicates FUNCTION key is activated
D “D” indicates Damp (exponential) function is activated
~ “~” indicates all damping is off
