…5 OPERATION AS A METER
Immerse the combination pH electrode in the
4 pH buffer solution and allow the displayed
reading to stabilise.
6 Adjust the 'CALIB' control to achieve a
4 pH reading on the digital display.
Remove the electrode from the buffer
solution and wash the electrode using
demineralised water. Carefully wipe the
excess water from the electrode using a
soft tissue.
Immerse the electrode in the 9 pH buffer
solution and allow the displayed reading to
stabilise.
7 Adjust the 'SLOPE', control to achieve a
9pH reading on the digital display.
Repeat
6
and
7
to obtain the best
accuracy.
5.1.1 pH Measurement – Fig. 5.2
1
Connect the electrode to the BNC socket.
2 Set the Function switch to 'MEASURE'.
3
Set the Mode switch to 'pH'.
4 Set the 'TEMP °C' control to the
temperature of the sample solution.
5 Set the Power switch to 'ON'.
Immerse the combination pH electrode in the
sample solution and note the pH value when
the display has stabilised.
5.1.2 Temperature Measurement –
Fig. 5.3
1 Set the Function switch to 'MEASURE'.
2 Set the Mode switch to 'TEMP'.
3 Connect the temperature probe to the
temperature socket (3mm jack plug).
4 Set the Power switch to 'ON'.
Immerse the probe approximately 1 inch below
the surface of the sample solution.
Note the temperature when the display has
stabilised.
