Measurement procedure:
The steps up to the selection of the parameter value to be determined are the same for all
procedures and described on page "TEST-5". Please observe the important notes for
accurate measurements on pages "TEST-8" and "TEST-9".
One-Time-Zero:
Measure new ZERO
Use last ZERO
For the sake of precision select "Use last ZERO" only
if the stored ZERO value is used with the
same cuvette and the same water sample for the test!
!
If after switching on the device you have already performed the
ZERO (baseline) adjustment for the same type, the following
message is displayed:
-> Measure new ZERO = continue with step 2)
-> Use last ZERO = continue with step 4)

Possible messages in the line below the measurement value:
"low! / high! / good!":
Assessment of the measurement value relative to the ideal range defined by you.

-> In order to obtain as precise a result as possible it is essential that the water
sample has a volume of exactly 10ml.
