4. OPERATION
Preparations before start
a) Insert multi-function electrode support (4) in the seat of multi-function electrode support
stand rack (*1).
b) Install pH combination electrode (12) on electrode support stand (4).
c) Take off the sleeve (13) of pH combination electrode, take off rubber sleeve, then small
hole on tope of the electrode appears.
d) Clean the electrode with distilled water
4.1 Calibration
4.1.1 Automatic
calibration
(Be suitable for calibrating pH 4.01
ǃ
pH7.00
ǃ
pH10.01 standard buffer solution)
You must calibrate before operating the meter. Generally, the meter should be
calibrated once a day when it is for continuous use.
The meter have a auto recognition function that can certificate PH4.00, 7.00 and
10.01 three PH buffer solution. Do not press
Ÿź
button to adjust data after
pressed “STD” key or “Slope” button, it is direct to press “Enter” button and then
finish calibration.
To press “STD” button to do one point calibration;
To press “Slope” button to do two point calibration
The meter can do other calibration that it is not PH 4.00, PH 7.00 and PH 10.01 PH
buffer. Adjust PH value in the state of calibration to the PH value of the standard
solution at this temperature, to press “Enter” button and then finish.
a) Pull out Q9 short-circuited plug(14) from the measuring electrode socket (6);
b) Insert combination electrode (12) into the measuring electrode socket (6);
c) If users don't use combination electrode, insert glass electrode plug into the
electrode socket (6), insert reference electrode in reference electrode terminal (7);
d) Turn on the meter, the screen displays the model, slope and E0, enter the
measuring state automatically. Press “ pH / mV” button, the meter will enter pH
measuring state;
e) If the temperature electrode is connected to the meter, insert the temperature
electrode into the solution, the meter will measure temperature value automatically;
if the temperature electrode is not connected to the meter, the meter will display
temperature value which is set by manual. Press "
Ÿ
" or “
ź
” of Temp button to
adjust temperature value larger or smaller manually at the pH measurement state
(only at the pH measurement state), to make temperature value the same as the
temperature of measured solution, then press “Enter” button.
