E40 If the test result appears with Overrange/Underrange,
User cal. a user calibration is not possible
here not possible Check sources of error, e.g.: user error (correct procedure,
observance of the reaction time, ...)
Jus Overrange E4, When the user makes calibrations,
Jus Underrange E4 the setting of the specified value
is possible only within defined limits.
These were exceeded or, respectively, not reached.
Overrange Measuring range exceeded
Turbidities in the sample
Light entering measurement compartment
Overrange During the user calibration the upper measuring-range limit
E1 was exceeded while setting to the specified value
Underrange Result below measuring range
Underrange E1 During the user calibration the lower measuring-range limit
was not met while setting to the specified value.
Zero Too much, too little incident light
not accepted
Printer Timeout Printer inactive, no connection
Storage-system Power supply for storage
error system interrupted or not available.

Measures
The battery capacity will be
out soon. Recharge battery pack;
operate the unit with mains adapter
Use a test with a standard
of lower/higher concentration
Check error sources, e.g.:
user error (correct procedure,
observance of reaction time,...)
standard (sample weight, dilution,
age, pH,...)
Repeat adjustment
Where possible dilute sample or
select another measuring range
Heed possible interferences
Seal ring attached to cell lid?
Repeat measurement with seal
ring attached
Carry out test with a standard
of lower concentration
State result with lower than x mg/l
x = Lower limit of measuring range;
if necessary use a different
analytical method
Carry out test with a standard
of a higher concentration
Zero cell in place?
Insert zero cell,
repeat measurement
Clean measurement compartment
Repeat zero calibration
Connect printer,
check contacts,
switch on printer
Insert or replace the lithium
powerpack. Then execute mode 34
to delete the data
Seal ring attached to cell lid?
Repeat measurement with seal
ring attached
