With this option installed you can change the scale factor of the display to read in different units of pressure or in arbitrary numbers that you choose If your system is set up with pressures in bars for example you might want the Smart Switch display to show bars instead of psig The r Hi r Lo and Loc menu functions allow you to scale the readout to your preference In the following example millibars are used You have a scalable 801P5 with the 15psig sensor You want to represent the pressure in millibars The standard conversion unit is psi 68 95 millibars You want to read zero for zero pressure therefore r Lo 0 Full scale output pressure for the 801P5 for this example is 15 psig So r Hi 68 95 x 15 1034 25 millibars which rounds to 1034 Therefore r Hi should be set to 1034 The unit now reads from 0 to 1034 millibars for 0 to 15 psig pressure The accuracy is 2 millibars which is 0 2 of 1034 You can use the scalable readout to set the display to read whatever units are most familiar to you or arbitrary numbers such as 0 to 10 With the 4 digit display you can use positive numbers to 9999 and negative numbers to 999 for fewer digits use leading zeros Page 21 801 5 Smart Switch To change the r Lo and r Hi 1 Press the MENU key and use the UP DOWN ARROW keys to move through the menu selections to r Lo 2 Press SELECT The furthest right digit will blink 3
