Operang Modes and Operaon
1) CTRL (control)
The CTRL mode is used for calibraon of pressure sensors, switches and other pressure equipment.
The pressure pump is acve and regulate the corresponding target pressure. The internal sensor
displays the actual value on the LCD.
• Connecon
Pressure devices have to be connected to the + and the - port of the calibrator. Absolute pressure
devices have to be connected to the + port.
• Se ng
- Press the MENU bu on. Confirm MODE with OK and press UP/DOWN unl CTRL is shown on the
display. Confirm with OK bu on.
- Set the upper limit of the range in the submenu RANGE (UP/DOWN and 0%/100%), confirm with
OK.
- Set of the unit in the submenu UNIT (UP/DOWN), confirm with OK.
- Set the step sequence (in %) in the submenu STEPS (UP/DOWN and 0%/100%) and confirm with
OK.
- MENU bu on to exit the submenu.
• Use
The unit is located at exit from the menu in VENT mode, ie the sensor of the calibrator is vented. On
the middle of the top, the target pressure is displayed. On the bo on of the display, the % value is
shown. When leaving the menu, this value is 0%. Switch between target pressure and % value with
the OK bu on.
- The % value can be changed with the UP/DOWN (in the fixed step sizes) and using the 0% / 100%
bu ons.
- The target pressure can only be changed with UP/DOWN. With 0%/100% to the appropriate place,
the target pressure be jumped.
• Example
Target pressure: By pressing the OK bu on, you can switch between the % and target pressure value.
Press OK buton unl the value (top center display) outlined in bold. Press the 0% or 100% bu on to
jump to the selected locaon. Choose the required value with the UP and DOWN bu ons. Push the
OK bu on to exit target pressure. The marker moves to the % value (middle of the display).

- Nominal value: right below
- Unit: right above
- Actual value: on the display of the connected device
- Reference value: middle of the display
You can make a manual zero of the internal sensor in the CTRL mode. Connected devices can be leak
testet:
- Manual auto zero: Push the ZERO bu on, the internal sensor is get to zero.
- Leak-Test: Push the LEAK bu on to switch off the pressure cell. The pressure is held. Control the
value via the display of the calibrator. Push the LEAK bu on again to stop the mode.
