bar/0.207 kPa, respectively. If the displayed value
does not match the output pressure, press OK, then
repeat this step (step 4) to further adjust the displayed
value. When the displayed value matches the output
pressure, select Done and go to step 5.
5. The instrument sets the output pressure to full
supply. The following message appears.
