Numeric Keypad
The default entry method provides 10 digits for numeric entry, plus the decimal point and sign key (Figure 6.4.1.3). Each key that is
pressed will display in the blue text box directly above the keypad. The sign key
will allow the user to toggle between positive
and negative values. This key can be selected at any point while entering a number. Once the desired value is entered in the blue
text box, the check button
can be pressed to change the setpoint to this value. If the value is outside of the setpoint minimum
or maximum limits, directly beneath the blue text box, the numbers will turn red and the setpoint change will not be accepted. To
clear an entry, select the cancel button
and the blue text box will be reset. The backspace button
is used to clear the last
character that was entered.

Number Pad Step
The number pad step method provides the same keys as the numeric keypad and also includes up and down buttons for quick
and easy setpoint changes. The number between the two arrows shows the value that will be added or subtracted from the current
setpoint when an arrow is pressed. The Up
button increases and the Down
button decreases the current setpoint by the
digital step value. The digital step value can be changed by entering a number using the numeric keypad and selecting either the
Up or Down button. The setpoint in Figure 6.4.1.4 will change by 14.5 psi each time the Up or Down button is pressed.
