Q&A:

Question 1: Why is the output voltage le than the nominal voltage

Answer 1: This may be the load is too large, or the power of the power supply is too small

Question 2: Why is there no negative voltage output or the output is too low?

Answer 2: Negative voltage cannot be used alone. When using negative voltage, the same load must be added to the positive voltage terminal.
