Other potential sources of error

Problem
The colorimeter runs off mains power,
but not with the otherwise fully
functionable battery pack.
42
Possible causes
LED used is too bright
Light path in measurement compartment is completely blocked
Optics unit is mechanically defe
Electronic defect on mainboard
It is not possible to calculate a value
(e.g.: bound chlorine).
Possible cause
Fuse (type A, delayed action, 20 mm)
is defective
Measures
Perform a software update
Initialize LED parameters
see chapter 4.1
Clean measurement compartment
Initialize LED parameters
see chapter 4.1
Correctly measured?
If not, repeat
Example: 1
While the values displayed
differ in terms of magnitude,
in consideration of the tolerances
they are identical.
In this case there is no bound
chlorine present in the sample.
Example: 2
The result for free chlorine lies
outside the measuring range,
which is why the value for free
chlorine cannot be calculated.
Since no detectable free chlorine
is present, the proportion of
bound chlorine can be assumed
to be the total chlorine content.
Example: 3
The result for total chlorine lies
outside the measuring range,
which is why the unit is not able to
calculate the value for bound
chlorine. In this case the sample
must be diluted to obtain the total
chlorine content.
Measure
Replace fuse
