E−411 TEC control error disabled output.
E−412 Analog section status is all 1’s or all 0’s (power down).
E−413 Serial EEPROM checksum error.
E−415 Sensor short disabled TEC output.
E−416
E−419
Incorrect Configuration for Calibration Sequence to start.
Setting a measurement is only valid during the calibration phase for that measurement. User
has tried to calibrate a measurement without first entering the required calibration mode.
E−501 LASER interlock disabled output.
E−503 LASER open circuit disabled output.
E−504
E−505
LASER current limit disabled output.
LASER voltage limit disabled output.
E−507 LASER Power limit disabled output.
E−508 LASER output disabled because of TEC output off condition.
E−509 LASER output disabled because of TEC High Temperature Limit condition.
E−510 LASER out of tolerance disabled output.
E−511 LASER control error disabled output.
E−512 Analog section status is all 1’s or all 0’s (power down).
E−513 Serial EEPROM checksum error.
E−515 Laser Output must be off to change ranges.
E−516 Incorrect Configuration for Calibration Sequence to start.
E−517 Calibration for Laser Diode current must have the output on to start.
E−518 Calibration for the Monitor Diode must have the output on and the responsivity set to zero to
start.
E−519 Setting a measurement is only valid during the calibration phase for that measurement. User
has tried to calibrate a measurement without first entering the required calibration mode.
E−520 User cannot change the Laser Current set point while operating in a calibration mode for
another measurement.
