How do you zero an electrical instruments readings?

To zero an electrical instrument's readings, first ensure the instrument is turned on and properly calibrated. Then, locate the zero or tare function, often found as a button or switch, and press it to reset the display to zero while the probes or leads are in a known zero state (e.g., not connected to any circuit). If the instrument lacks a zeroing feature, you may need to manually adjust the readings based on known reference points. Finally, verify the zero setting by checking the instrument with a known zero reference after zeroing.
