* After the above ph 7, 4, 10 screen is selected, then
cooperate the relative standard solution, for example the
ph 7.00 calibration point should cooperate the pH 7.00 standard solution.
ph 4.00 calibration point should cooperate the pH 4.00 standard solution.
Press the " Enter Button " ( 3-8, Fig. 1 ) will
save the calibration data and finish the calibration
procedures.
* If select the clear point, press the " Enter Button "
( 3-8, Fig. 1 ) will clear existing calibration data.
* If select the Escape Calibration, press the " Enter Button "
(3-8, Fig. 1 ) will Escape Calibration Function and back nomal
measurement.
7) The complete procedures should execute
the two calibration points :
PH7 calibration
PH4 calibration ( or PH10 calibration )
* The calibration procedures should execute start from
pH7 calibration then follow pH4 ( or pH10 ) calibration.
* Rinse the electrode with distilled water again when
make each point calibration ( pH7, pH4 or pH10 ).
* Repeat above two points procedures two times at least.
