pH
83
8 Thoroughly rinse the electrode with deionized water.
9 If necessary, set the temperature of the second buffer
solution with
82 (see section 5.5.1).
10 Immerse the electrode and the temperature probe in
the second buffer solution.
11 Start the measurement with
g.
The
h display indicator flashes. The electrode
voltage (mV) appears on the display.
As soon as a stable value is reached,
h disappears.
The slope value (mV/pH) and the asymmetry value
(mV) appear on the display. The probe symbol shows
the calibration evaluation after the two-point
calibration.
12 Use g to go on to the three-point calibration
(ct3 appears on the display)
or terminate after the two-point calibration with
m
(the current calibration data are stored).
