ambient and Cell temperature differs
from set point by ± 10ºC for 90 secs..
If the temperature is not able to reach
the set point and is below the set
point.
If the temperature is not able to reach
the set point and is above the set
point.

Solution
Run a Clean Cycle and try to
clean the reaction cell with
detergent.
Check if overflow cap on top of
the reaction cell is loose.
Try a different set point
temperature. Call a service agent.
Re-calibrate the Thermistor.
Try a different set point
temperature. Call a service agent.
Re-calibrate the Thermistor.
Try a different set point
temperature. Call a service agent.
Perform Clean Cycle and
Calibrate Optics and thermistor.
Perform Clean Cycle and
calibrate optics and thermistor.
Solution
Check for possible external light
entering areas on the reaction
cell.
Perform Clean Cycle
and then Calibrate Optics.
Solution
Check for thermistor and heater
connections, and calibrate them.
