Triple Range (Optional)
When Triple Ranging is enabled the currently selected range will be displayed below the current pressure. To change to a different range make sure the pressure is below 100 psi (700 kPa). Then press the Mode key and then press Range [F5] until the correct range is displayed. If the current pressure range is exceeded the range will automatically change to the highest range until manually changed.
Main Menu
The Main Menu displays the measured pressure in double-sized numbers. Below the pressure reading is the current unit of measure and mode (Tare or Absolute). The Main Menu can always be reached by repeatedly pressing PREVIOUS. The RUSKA 7350 is designed such that all of the commonly used functions are accessible by a direct key on the key pad or from a top level function key. Less commonly used set-up type functions are accessible through the menu function key.

Controlling Pressure
The Control [F2] function key is used to place the Calibrator into the Control Mode. A pressure set-point should be entered into the Calibrator prior to placing the unit into the control mode. This is to assure that the operator is aware of the set-point valve prior to entering into the control mode.
Setting the Pressure Set-Point
The pressure set-point is the destination of the pressure control algorithm. It should be set before entering Control mode. The pressure set-point is set to zero at power-up or whenever a pressure error occurs.
1.The pressure set-point is set from the Main Menu. (Press PREVIOUS until the Main Menu appears.)
2.Use the numeric keypad to enter the new pressure set-point in the current pressure units.
3.Press ENTER to accept the entry or press CLEAR to clear the numeric scratchpad.
