Most ECG machines calibrate themselves when they are turned on. Older or cheaper models they may need prompting, each is different but the user manual should explain it. Calibration is usually set to 1mV = 10 small squares. This can be manually adjusted if the patient has an unusually large QRS complex. Hope this helps
An ECG (Electrocardiogram), or an EKG (Elektrokardiogramm) works by measuring electrical potential between various points of the body using a galvanometer (a very sensitive voltage meter). -DJ Craig

Eeach electrode connected to the patient is attached to the lead selector of ECG.This will determine which electrodes are necessary for a particular lead and will connect them to the remainder of the circuit. It can be controlled by the operator or by the microcomputer of the electrocardiograph. It selects one or more leads to be recorded. Source:John.G.Webster
If they guitar and mic are wireless you have to calibrate them in the settings.

An ECG machine should be calibrated regularly, typically every six months, or whenever it undergoes maintenance or repairs. Additionally, calibration is necessary if there are any signs of malfunction or discrepancies in readings. It’s also advisable to calibrate the machine before use in critical situations to ensure accurate results. Regular calibration helps maintain the accuracy and reliability of the ECG readings.
If the ECG machine malfunctions you will need to redo the test. You can try unplugging the machine and replugging it to see if that resets the system.
It can be tested with something called an ecg simulator.

Willem Einthoven Invented the accurate ECG using Strings Galvonometer, but Alexander Muirhead made the first prototype.
To operate an ECG machine, first ensure the patient is in a comfortable position and has been prepared by cleaning the skin and applying electrodes to specific locations on the chest, limbs, and sometimes the back. Turn on the ECG machine and select the appropriate lead configuration for the test. Instruct the patient to remain still and relaxed while the machine records the electrical activity of the heart, which typically takes just a few minutes. Once completed, review the printed ECG tracing for any abnormalities and ensure proper documentation.
An electrocardiograph (ECG) machine produces a printed representation on ECG paper by detecting and recording the electrical signals produced by the heart. The machine amplifies these signals and converts them into a visual display on the paper, showing the heart's electrical activity as a series of waves and spikes.
An input device for an electrocardiogram (ECG) is typically a set of electrodes that are placed on the skin to detect electrical activity of the heart. These electrodes capture the electrical signals generated by heartbeats and transmit them to an ECG machine or monitor. The machine then processes and displays the data as waveforms, allowing healthcare professionals to assess heart health and diagnose potential issues.
