I am getting error code E-15 in light sheer laser diode machine. And its related to calibration , but i have no idea how to do calibration.

Error Code E15 = “Calibration out of range.” This error code indicates a problem with the operating temperature being outside the range calibrated for the device. The Light Sheer system will most likely need to be recalibrated.
