1. Once input voltage is present, the module can be turned on or off using ON/OFF toggle switch.
2. User can change output voltage by using Vo1 or Vo2 Trim adjust potentiometer.
3. Please note the specified operating ranges and keep in mind the positive output units are step
down converters.
Please see the product data sheet plots for more details about the specified
operating range for specific units.

Set Up Example – Using Scope
A scope probe can be connected at input or output test points to observe dynamic performance such as
start up or transient response.
Startup from input voltage application
Be aware that on small voltage scales the loop formed by the scope probe’s ground lead will pick up
spurious switching noise.

Set Up Example – Using Scope
When making sensitive measurements a BNC socket or similar method should be added in order to
minimize loop area of the measurement and obtain accurate information.
