4 Parameter Flags
The instrument has several indication- and warning flags related to the measured
parameters. The flags are shown on the display as well as printed on the connect-
ed printer. An error flag should be seen as parameter value error. The sample
should be re-analyzed. A warning flag might indicate a pathological sample. If on
the same parameter both an error and a warning flag occurs; the error flag has
always a priority and is displayed and printed in the first place. Note that a param-
eter that is outside the “Normal Range” which is set in menu 5.4 is either marked
with “H” or “L” on the connected printer to indicate if the value is Higher or
Lower than the pre-set “Normal Range” values. The display will in such a case
show a “*” in front of the parameter value.
The following flags are seen as “Error flags” or “Warning flags”
