4.3.4 ConCal (pH)
Two-point
calibration
Use two buffer solutions for this procedure:
l
pH 7.0 ± 0.5
l any other buffer solution
Note
Steps 3 and 10 are not required if you use a temperature
probe.
1 Press the
m
key repeatedly until the pH/Redox
measurement appears on the display.
pH or U appears in the status line.
2 Press the
c
key repeatedly until the ConCal
function display appears.
3 If necessary, set the temperature of the buffer
solution using
u d
while keeping the
g
key
depressed.
4 Submerse the pH electrode in the first buffer solution
pH 7.0 ± 0.5.
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 appear on the display.
