PRGM/Enter Key 
PRGM
Document Symbol: (PRGM/Enter
→)
Measure Mode
(and EU Selection)
Selects Program Mode, which allows access to the programmable registers. This key is 
also used to accept a new Engineering Unit selection. 
Program Mode
Opens the selected programmable register for editing.
When the desired value is displayed, pressing the PRGM/Enter
→ key accepts and
stores the value, and closes the register.
When editing a multi-digit value, each key press will accept the current digit and proceed 
to the next, until finally accepting the complete value and closing the register.

Document Symbol: (Up
↑ and Down↓)
Measure Mode
In Measure Mode, pressing the Up
↑ and Down↓ keys at the same time resets the zero
reference of the gauge (see page 8).
Program Mode
(and EU Selection)
In Program Mode, for convenience, this function will reset the current value to default.
For example, in Program Mode (but before opening a register), this function 
will reset the register scroll to P0. 
After opening a register for editing, this function will reset the register’s data 
value to default (typically 0). 
Similarly, when selecting a new Engineering Unit, this function will reset the 
selection to the first unit (gallons). 
Note that even when using this “reset” function, the PRGM/Enter
→ key must be
pressed to accept the new value (this allows for further editing after reset of the value).
