Step/Jog

This feature is only available when operating in the single display mode. To place the ADTS in

the single display mode from the dual display screen press the MENU key. In addition to entering

the pressure set point through the keypad, the pressure set point can be changed using either the

step or the jog functions. The Step function is used primarily when the operator is controlling

pressure steps in equal pressure increments. The size of the pressure step is user defined. The

Jog function is most often used when calibrating mechanical gauges and the operator wishes to

change the pressure until the mechanical gauge indicates a cardinal point. The operator can then

read the higher resolution ADTS to determine the actual pressure value when the mechanical

gauge is indicating a cardinal point. The Step/Jog (the [F5] key) toggles between Step and Jog,

to switch between these modes, press the function key 5 [F5].

Ensure that the word Step is highlighted in the Step/Jog (the [F5] key). Using the rotary knob,

rotate the knob clock-wise to increase the set point, or counter clock-wise to decrease the

controller set point. The scratchpad will be updated to a new set point. The step size defaults to

10% of full scale. Press ENTER to accept the new set point.

From the Main Menu (press PREVIOUS until the Main Menu appears), press Menu [F6],

Menu [F6], Setup [F2], and then User [F2]. Using the rotary knob, move the cursor to highlight

Step Size. Enter the desired step size in the current pressure units and press ENTER.

Assure that the word Jog is highlighted in the Step/Jog (the [F5] key). From the Single Display

Menu, the pressure set point can be modified by rotating the rotary knob clockwise to increase

pressure and counterclockwise to decrease pressure. Each increment or decrement will change the

pressure in the least significant digit. Continually rotating the rotary knob, the pressure will

continue to change until the rotation is stopped.
