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 (InH
2
O).
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).
