Trim output voltage up by connecting an external resistor between Pins 5 and 6. Use the following

equation, reference Table 1 for variables A.

Example:

Trim both outputs 5% up for 12V Output units,

where A = 1.98,

Trim output voltage down by connecting an external resistor between Pins 7 and 5. Use the following

equation, reference Table 2 for variables C and D.

Example:

Trim 4% down for 5V Output units,

where C =1.24, D = 26.5,
