Setra System Model 370 - Manual (Page 13)

Section Three
DIGITAL PRESSURE GAUGE FUNCTIONS
3.1 ENTERING A NUMBER OR FUNCTION
To enter a number or function, simply press the key or keys which
correspond to the numbers or functions you wish to enter.
3.2 CLEARING A NUMBER OR FUNCTION
To clear a function or number you have begun to enter, press the CLEAR
key. This automatically returns the gauge to display mode, without affecting
any other functions which may be in use.
To reset the Model 370 to its power up condition, press "-", then CLEAR.
This clears the zero/tare value, shuts off MIN/MAX, and converts back to
the original engineering units. All of these functions are described in later
sections of this guide.
3.3 IF YOU MAKE A MISTAKE
If you mis-enter a number or enter a number or function the gauge cannot
accept, the display will read "UnAbLE". Press CLEAR to resume normal
display, and re-enter the number or function.
