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 " ( 5-1, Fig. 2 ) into the " PH Socket/BNC
Socket " ( 3-16, Fig. 1 ).
2) Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
Select the Meter's measurement Mode to " 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 12-13, page 46.
* Automatic temperature compensation, it
should plug in the ATC probe ( optional, TP-07 ).
.
4) Hold the " Electrode Handle " ( 5-2, Fig. 2 ) by hand
and let the " Sensing head " ( 5-3, 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 imerse the
ATC ptobe into the solution together.
