A multi-turn trimmer is usually present to fine-tune the output voltage. Turn counter-clockwise to decrease voltage and clockwise to increase it.
Note: this document is a technical monograph-style summary and practical guide for HW-133-v1.0 (hereafter “HW‑133”), covering specifications, electrical/physical interfaces, typical applications, integration guidance, troubleshooting, test procedures, and example designs.
