Is there a way to detect the deterioration of the LD laser diode?
When the power is turned ON, Lddwn* will appear on the sub-digital display of the Amplifier.
When this display appears, it means that the laser diode has deteriorated and the Sensor must be replaced. Only the Sensor of the Smart Sensor needs to be replaced. The Amplifier can still be used.
