User adjust function allows manual adjustment of the output current,
this is useful for minor calibration adjustment or trimming out any
sensor error, ± 5% of range adjustment is available at both offset and
span. Raise and lower buttons are provided on the front panel, of the

screw driver into the appropriate slot to operate the button. The button
has a click action.
METHOD
