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.
