Single-point
calibration
Only the electrode asymmetry is determined in single-point
calibration. The slope of the last two-point calibration is re-
tained.
Use a buffer solution in the range pH = 7.0 ± 0.5 for this pro-
cedure.
Note
Step 3 is not required if you use a temperature probe. The
TP message indicates an active temperature measurement.
1 Press the
m
key repeatedly until pH or U appears in
the status line.
2 Press the
c
key repeatedly until the ConCal func-
tion display appears.
3 Set the temperature of the buffer solution using
u d
while keeping the
g
key depressed.
4 Submerse the pH electrode in the buffer solution.
5 Press the
g
key.
The measured pH value appears on the display.
6 Set the nominal pH value of the buffer solution (at the
current temperature) by pressing the
u d
keys.
7 Press the
g
key.
The value of the asymmetry (mV) and the sensor
symbol for the evaluation of the electrode appears on
the display.
8 To return to the measuring mode: Press the
m
key.
