Beckman Coulter/Optima TL 100 - Temp error message
We have encountered "TEMP" error message blinking on our Beckman Optima Max. At the same time, the temperature is showing app -5.0C. Checked the chamber temperature sensor and it's app 840 ohm and it should be PTC1000 type sensor. Is there a problem with the temperature sensor? The instruction manual indicates that it could be something related to the brake. May I have the circuit diagram or service manual for it? Advise this member.
