Error "ERR": This "Err" indication is displayed when the instrument temperature is below -10º or above 85º. In this case, it is required to bring the device into a heated room to heat the device to room temperature or turn off and cool the device to the operating mode. After the device enters the range of operating modes, the indication will disappear.

To turn off the device, press and hold the button. The display will go out and the device will switch off.
