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

reference Table 1 for variable A.

Example:

Trim 5% up for 12V Output units,

where A = 1.98,

Δ % = 0.05

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,
