Output Adjustment all HR151 models (single output):
The output can be adjusted upward by using the output
adjust (pin3). The resistance between output adjust (pin 3)
and output common (pin 4) will determine the magnitude
of the increase in the output. The table above is only
applicable to HR151-2805.
