There are three action keys below the number keys that operate on the numbers displayed in the input
value window:
Press the Enter [
] key to accept the value showing in the number echo
window into the system for immediate use.
Press the Backspace [
] key to erase the last number entered in the string.
Multiple presses will back out multiple digits.
Press the Delete [
] key to delete the entire value showing in the echo window
to start a new, or to abort.
Number Pad / Step
The “Number Pad Step” key pad functions in two different ways:
(1) A setpoint can be entered in the same way as the Number Key
Pad above: key in the number and press Enter [
], that
number is then immediately accepted into the setpoint value.
(2) Key in a number and press the Step Up [
] or the Step
Down [
] key, (without pressing the Enter [
] key),
that number will be used to decrease or increase the existing
setpoint value.
Subsequent touches of the Step Up or Step Down key will continue
to increase or decrease the setpoint by this step value until a new
value is keyed in followed by a key press of the Step Up [
] or
the Step Down [
] key. If the Enter [
] key is pressed the
newly entered value will register as a new setpoint value on the
main screen rather than a step value.
Digital Step
In the digital Step Data Entry Mode there is initially a string of five
white zeros (0) and one blue numeral one (1) across the top as
shown in the figure to the left. Any one of these zeros can be
converted to a blue 1 by touching it. Slide a finger across the
zeros to demonstrate this action. Using this feature each digit of
the setpoint can be increased or decreased by one digit at a time
by activating the corresponding digit with a blue 1 and pressing
the Up [
] or Down [
] key.
For example, in the screen below the setpoint is at 50.0000, and the operator would like to change this
to 51.0000, 52.0000, 53.0000.... and so on. He simply has to touch the digit in the Digital Step that
corresponds to the “ones” digit in the Setpoint, thereby activating that digit and then press t
he Up [
] key to increase that digit.
