Operation pH 720
28
Note
If the slope ( SLO ) is indicated on the display, you can
change the unit of the slope with
28
.
The display in % refers to the Nernst slope, 59.2 mV/pH
(100 x the slope determined/Nernst slope).
8 Thoroughly rinse the electrode with distilled water.
9 If necessary, set the temperature of the second buffer
solution by pressing
28
.
10 Submerse the electrode in the second buffer solution.
11 Press the
g
key.
The second measured pH value appears on the dis-
play.
12 Set the nominal pH value of the second buffer solu-
tion (at the current temperature).
13 Press the
g
key.
The value of the slope (mV/pH) appears on the dis-
play.
The sensor symbol shows the evaluation of the elec-
trode after the two-point calibration.
14 Press the
g
key.
The value of the asymmetry (mV) appears on the dis-
play.
15 To return to the measuring mode: Press the
m
key
or continue with the three-point calibration.
