Cause
Solution
Testing optics, low signal
level . . .
Cell may be coated and may
require cleaning.
Low light output from Optics.
Optical window of cell may be coated.
Run a Clean Cycle and try to
clean the reaction cell with
detergent.
Testing optics please check
for stray light
External light is entering the cell.
Check if overflow cap on top of
the reaction cell is loose.
Please check for heater
failure
If heater is enabled in Method, and the
Set point temperature is higher than
ambient and Cell temperature differs
from set point by ± 10ºC for 90 secs..
Try a different set point
temperature. Call a service agent.
Checking the reaction
temperature. Temperature
below set point.
If the temperature is not able to reach
the set point and is below the set
point.
Re-calibrate the Thermistor.
Try a different set point
temperature. Call a service agent.
Checking the reaction
temperature. Temperature
above set point.
If the temperature is not able to reach
the set point and is above the set
point.
Re-calibrate the Thermistor.
Try a different set point
temperature. Call a service agent.
Taking blank measurement,
unstable signal.
Unstable temperature, Cell may be
coated, or may be due to Optics
failure.
Perform Clean Cycle and
Calibrate Optics and thermistor.
Collecting data, unstable
signal
Unstable temperature or cell may
be coated, or may be due to optics
failure.
Perform Clean Cycle and
calibrate optics and thermistor.

Cause
Solution
Unstable signal, stray light is
high please check.
Some external Light is entering in to
the cell.
Check for possible external light
entering areas on the reaction
cell.
Optimum light level.
Calibration is aborted.
Cell may be coated.
Perform Clean Cycle
and then Calibrate Optics.

Cause
Solution
Temperature below set point
please check for hardware
malfunction.
May be due to the connectors or the
thermistor or heater malfunctioning.
Check for thermistor and heater
connections, and calibrate them.
Temperature above set point
please check for hardware
malfunction.
May be due to the connectors or the
thermistor or heater malfunctioning.
Check for thermistor and heater
connections, and calibrate them.
