A filter setting too low for your setup willresult in a “jumpy” display. RPM display will change at your base resolution and no smoothing will happen. Choose thelowest setting that will result in a smooth display for greatest sensitivity of the reading.4.8 Pressure SetupThe pressure setup menu item allows the user to adjust the pressure sender properties.Move the highlight over this menu item and press the rotary button to return to the main menu.Select whether to use the pressure sender or not.Select if you are using a resistive or a linear voltage output pressure sender.Select what type of pressure sender you are using. Select “VDO” for VDO/Resistive pressuresenders or “USER” for a custom sender. This menu item is fixed on “USER” if the linear pressuretype is selected.If the “Resistive” pressure sender is selectedEnter the maximum resistance of your pressure sender. Common VDO pressure senders aretypically 180 Ohms.Enter the maximum pressure for your pressure sender. If you are using a VDO 10 bar pressuresender then enter in 10.0, if you are using a VDO 5 bar, then enter in 5.0, if you are using a VDO 2bar then enter in 2.0. Enter the maximum pressure in the selected unit VDO 10BAR = 145PSI.Select whether your pressure sender increases resistance with pressure or decreases resistancewith pressure. VDO senders normally increase resistance with pressure.If the “User” pressure sender is selectedIf the sender type is set to “USER”, then use this menu option to calibrate yourtemperature sender.
