The instruments K 100 PR and K 100 W PR can be used for pH or ORP
measurements.
pH measurement
pH measurement requires a calibration.
By means of calibration the electrode´s characteristics are determined and stored. The
procedure is a subsequent measurement of two solutions with a known pH. The pH
values of the buffers used asd calibration solutions are stored in the menu basic
settings.
You have to adjust the calibration data only if you want to use special calibration
solutions or electrodes with a special buffer solution.
The electrode´s slope is influenced by temperature. This influence can be
compensated by manual or automatic compensation. Manual compensation means
that the temperature is entered manually. Automatic compensation requires
measuring the temperature with a Pt100.
ORP measurement
At works the instruments are set for pH measurement. For ORP measurements you
have to switch to ORP measurement.
This is the only adjustment. ORP measurements do not require calibration or
temperature compensation. Therefor the parameters „calibration" and „temperature
compensation" do not appear in the menu if ORP measurement has been selected.
Calibration of the pH measurement, display of slope and zero-point.
Selection of manual or automatic temperature compensation, adjustment of
temperature for manual compensation.
