Switching between pressure units (PSI and BAR) on your Slime 40063 Digital Pro Power Tire Inflator is simple. Here's how: First, press and hold both the plus (+) and minus (-) buttons simultaneously. Keep holding them for about five seconds until the display starts to flash. Next, use either the plus (+) or minus (-) buttons to cycle through and select your preferred unit of measurement, either PSI or BAR. Finally, after you've made your selection, wait a few seconds (about 2-3 seconds), and the display will update to show the chosen unit. From then on, the Slime 40063 Digital Pro Power Tire Inflator will show pressure readings in your chosen unit.
