6. Set the stabilization range to between 0.01 and 9.99 ppm. The default values are
shown in the table. Press ENTER to save.
7. The display returns to the
StABiLiSE
prompt. Press NEXT. The next screen depends
on the measurement being made. For free or total chlorine see step 8. For oxygen,
see step 9. For ozone see step 10.
8. If the measurement is free or total chlorine, the
SLOPE
prompt appears. Use
é
or
ê
to toggle between
SnGL
(single) or
duAL
(dual) slope. Press ENTER. Go to step 10.
NOTE
For the vast majority of applications, single slope calibration is accept-
able. Dual slope calibration is useful in fewer than 5 % of applications.
9. If the measurement is oxygen, the
SALnty
(salinity) prompt appears. Use the arrow
keys to enter the salinity of the water. Press ENTER. Go to step 10.
10. The display returns to the
SPAn CAL
screen. Press NEXT.
11. The
0 CAL
screen appears. Press ENTER.
12. Enter the desired zero limit. The units are the same as the units programmed in Sec-
