played data values

• Take the HI93703-0
bottle containing the
ZERO FTU* Standard
(or turbidity-free dilu-
tion water) and fill the
measurement cuvet.
Note: in order to minimize any error intro-
duced by the cuvet, it is recommended to
use, during calibration, the same cuvet
you are going to use to perform the mea-
surement.
• Insert the cuvet with
the HI93703-0 @
ZERO FTU* standard
solution (or turbidity-
free dilution water)
into the measurement
cell and press the
CAL key. A blinking
"SIP" message indi-
cates that the instru-
ment is performing
the measurement.
After approximately
50 seconds the in-
strument will ask for
the HI93703-10 stan-
dard solution @10
FTU* by displaying
"10.0".
• Repeat the same procedure with HI93703-
10 @10FTU* standard solution.
