4.6.5 Calibration

Why calibrate?

pH electrodes age. This changes the asymmetry (zero point) and slope of the
pH electrode. As a result, an inexact measured value is displayed. Calibration
determines the current values of the asymmetry and slope of the electrode
and stores them in the measuring instrument. Thus, you should calibrate at
regular intervals.

When to calibrate?



After connecting another combination electrode



When the sensor symbol flashes:
– After the calibration interval has expired
– after voltage interruption (e.g. empty batteries, empty accumulator

pack)

Buffer sets for cali-

bration

You can use the buffer sets quoted in the table for an automatic calibration.
The pH values are valid for the specified temperature values. The tempera-

Calibration

Calibr. interval

1 ... 999 d

Calibr. interval

for the pH elec-

trode (in days).
The meter reminds you to cali-
brate regularly by the flashing
sensor symbol in the measured
value display.

Unit for slope

mV/pH
%

Unit of the slope.
The % display refers to the
Nernst slope of
-59.16 mV/pH (100 x determined
slope/Nernst slope).

Man. temperature

-20 ... +130 °C

Entry of the manually determined
temperature. For measurements
without temperature sensor only.

Temperature unit
