4. Input the buffer value when the probe is in its isopotential point and with
which our probes are accompanied with.
Then the display shows:
pH Calibr
Put Izopot buff
Buf=xx.xxx
V=x.xxxV Set
Where x.xxx is measured by the probe voltage.
5. After the readings calm down, the operator has to press the button below
the inscription Set.
6. Repeat the procedure with Next buffer.
The following is displayed:
pH Calibr OK
This means that the procedure for analyser calibration was successfully
completed.
7. pH measuring mode is started automatically.
8. Check calibration correctness by measuring buffer solution 7.00.
9. pH Measuring.
After starting this menu the measurement is done in mode off line, i.e. the
analyser works only as a pH meter. The operator has to dip the probe in the
sample and on the display the following is shown:
pH measuring
x.xxxV
y.yy pH
Exit
Where:
x.xxx – measured by the probe voltage
y.yyy – measured probe’s pH
