How to Control CC/CV on the TP3005DM

Hi,<br> <br> The CC/CV on the TP3005DM just randomly changes control, and if its in CV I cannot control the current(which defaults to zero), and I can't get the full 30 volts access. This is problematic because I'm using a low current circuit, and I'm having smoke come off the PCB when I use it. Any help would be appreciated for how to control this.

The&#160;TP3005DM is not a model I recognize. &#160;A google search shows it as made by company “TekPower” not Tektronix.<br> <br> Consider our various single channel models from the 2200 series.<br> https://www.tek.com/en/products/keithley/dc-power-supplies/2200-dc-power-supply<br> &#160;
