6. Type CAL:PRES6:VAL1 xx.xx (xx.xx = value in units must be absolute)
again.
7. Connect the supply line to the supply port.
8. Slowly adjust the regulator to apply 3000 psi absolute to the reference and
the supply port.
9. Type CAL:PRES6:VAL2 xx.xx (xx.xx = value in units must be absolute).
Note
The isolation valve should still be open so that the supply port
pressure gauge receives pressure at this step.
