Caution: Observe the correct polarity when connecting the power supply. The red lead (from pin B) must be connected to the positive terminal, typically labelled ‘+’, and the black lead (from pin A) must be connected to the negative terminal, typically labelled ‘-’. An incorrect connection risks destroying both the instrument and the power supply.
