Piston Origin Fault
This alarm is initiated during the piston reset routine if the piston comes
down until it is dark, but then fails to find light when the piston is raised.
1. Check that the LED and detector are connected correctly and
working.
2. Check the measurement cell and piston.
Piston Reset Fault
This alarm is initiated during the piston reset routine if light is always read
at the detector, regardless of the piston position.
1. Check that the LED and detector are connected correctly and
working.
2. Check the measurement cell and piston.
Priming
The analyzer is priming the tubing. The priming routine draws in each
reagent, sample and standard in turn, filling the tubing and then pumping
to waste.
An automatic calibration starts when the priming routine is completed.
Reagent n Empty
The indicated reagent bottle (n) is empty.
 Replace all reagents at the same time.
Temperature Stabilizing
This message is displayed at startup and remains until the measurement
head temperature has stabilized to within 1% of the programmed
operating temperature.
