What to do if my QAL Medical Equipment shows error codes E1, E2, E3, E4, E6, E7, E8, E12, E13, E14, E15, E16, or E18?

If your QAL Medical Equipment displays error codes E1, E2, E3, E4, E6, E7, E8, E12, E13, E14, E15, E16, or E18, this could be due to several reasons. It might be out of calibration, in which case you should re-calibrate the unit following the calibration procedures. Alternatively, there could be a Main PCB failure (replace the PCB), a Controller cable break (replace the Controller cable), or a Controller PCB failure (replace the Controller).
