MRC PH-230SD - Page 12

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 " ( 3-16, Fig. 1 ).
2)
Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
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 8-8, page 25.
* Automatic temperature compensation, it
should plug in the ATC probe ( optional, TP-07 ).
.
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 imerse the
ATC ptobe into the solution together.
