4. PH CALIBRATION PROCEDURE 4-1 Calibration Consideration The most ideal PH ELECTRODE generates 0 mV at PH 7.00 ( 177.4 mV at PH 4 ) and YK-2001PH has been always calibrated with signals which simulate the most ideal PH ELECTRODE ( based on 25蚓 ambient environment ). However not every PH ELECTRODE is as accurate as the most ideal one, so calibration procedures are necessary to be done before the first time measurement.

4) PH 7 calibration Connect the PH ELECTRODE with the " BNC socket " ( 3-10, Fig. 1 ) and immerse the electrode in the PH7 buffer solution. Press the " CAL Button " ( 3-8, Fig. 1 ) then the upper display shows texts of " CAL " and the lower display shows the default calibration value. CAL 7.00 * The texts " CAL " will flash for around 5 seconds. After that, the meter calibrates itself automatically. The upper display will show the calibrated value, the lower display will show the temperature value. 7.

CAL 4.00 * The texts " CAL " will flash for around 5 seconds. After that, the meter calibrate itself automatically. The upper display will show the calibrated value, the lower display will show the temperature value. 4.00 25.0 6) Rinse the electrode with distilled water again. 7) Repeat above (4) to (5) procedures two times at least. 8) The instrument and electrode are now finished the " TWO POINTS CALIBRATION " & ready for the measurement.

4-5 Others Above calibration procedures effect only when reading value within 1 PH of the calibration point. However if the reading value beyonds * 1 PH of PH 7 ( > PH8, < PH6 ) * 1 PH of PH 4 ( > PH5, < PH3 ) * 1 PH of PH 10 ( > PH11, < PH9 ) the calibration procedures are : 1) Connect the PH ELECTRODE to the " PH BNC Input Socket " ( 3-10, Fig. 1 ). 2) Power on the instrument by pressing the " Power Button " ( 3-2, Fig. 1 ). 3) Press the " PH/mV Button " ( 3-6, Fig.

5. PH TEMPERATURE COMPENSATION Enable the meter to gain high accuracy measuring results from different kinds of solution, the temperature compensation calibration procedures are necessary to be executed. Manual temperature compensation calibration procedures please refer to 5-1 ( See below). Automatical temperature compensation calibration procedures please refer to 5-2 ( Page 15 ).

a. Adjust the temperature compensation value * Press the " TEMP. C Button " ( 3-7, Fig. 1 ) first, The upper display will show the measured PH values. the lower display will show the manual temperature compensation value. PH 7.91 026.1 蚓 @ Use the " Left Button " ( 3-6, Fig. 1 ), " Up Button " ( 3-5, Fig. 1 ) and the " Down Button " ( 3-8, Fig. 1 ) to adjust the manual temperature compensation value. b. Adjust the PH 4 default calibration value * When the manual temp. compensation values be adjusted.
PAGE 15
@ Use the " Up Button " ( 3-5, Fig. 1 ) and the " Down Button " ( 3-8, Fig. 1 ) to adjust the PH 4 default calibration value. @ The adjustment range of " PH4 default calibration value " is limited within 4.0 0.20 PH c. Adjust the PH 7 default value * When the PH 4 default value be adjusted. Press the " TEMP. C Button " ( 3-7, Fig. 1 ) once again to adjust the PH 7 default calibration value. The upper display will show the values of " 7.

The upper display will show the values of " 10.00 " and the lower display will show the " PH 10 default calibration value ". PH 10.00 10.02 @ Use the " Up Button " ( 3-5, Fig. 1 ) and the " Down Button " ( 3-8, Fig. 1 ) to adjust the PH 10 default calibration value. @ The adjustment range of " PH10 default calibration value " is limited within 10.0 0.20 PH e. Finish the adjustment * When the PH 10 default calibration value be adjusted, press the " TEMP. C Button " ( 3-7, Fig.
