Required Equipment for Calibration
1)pH ELECTRODE ( optional ).
2)pH buffer solutions ( optional ).
Calibration Procedure
1)Prepare the pH Electrode ( optional ), install the
" Probe Plug " ( 4-1, Fig. 2 ) into the " pH Socket/BNC
Socket " ( 3-11, Fig. 1 ).
2)Power on the meter, set the mode to the pH
measurement, the right bottom display will show " pH ".
3)Adjust the " Temperature Compensation Value " to
make it same as the temperature value of the pH
buffer solution.
* Manual temperature compensation value
adjustment procedure, refer to 9-7, page 38.
* Automatic temperature compensation, refer
to 5-2, page 13.
.
4)Hold the " Electrode Handle " ( 4-2, Fig. 2 ) by hand
and let the " Sensing head " ( 4-3, Fig. 2 ) immersed
wholly into the measured solution and little shake the
probe.
Display will show the pH value.
* If use the ATC probe, should immerse the
ATC probe into the solution together.
