pH measurement pH measurement
1.
Select the desired mode (pH) by pressing
MODE.
The display will immediately
show the measured value according to the previous calibration. Should you
want to recalibrate, press
CAL
.
2.
The instrument permits to choose between the buffers in memory (1.68, 2.00,
4.00, 4.01, 6.87, 7.00, 9.18, 9.21, 10.01, 12.00, 12.45 + max. 5 user tables).
Select the proper values and press
OK
. The unused buffers should be switched
off.
3
. Rinse the electrodes with distilled water and immerse them in the first buffer
solution. Select [CALIBRATE], press
OK
and follow the in struc tions on the
screen until the calibration is finished.
4.
After rinsing the electrodes with distilled water, immerse them in the samples
and read the display.
5.
Rinse the electrodes always with distilled water after use and store them in a
3...4 M KCl solution.
Using pH electrodes with an abnormal zero point:
1.
Press
CAL
.
2.
Select [Eo = x mV] and press
OK
.
3.
Enter the zero point of the elec tro de and press
OK
.
• Hold
MODE
pressed and press
MODE MODE
ê
to change the resolution from 0.1 to 0.001
pH.
Temperature measurement
1.
Select the desired mode (°C) by pressing
MODE
. Should you want to recali-
brate, press
CAL
.
2
. Immerse the Pt1000 in a solution of known temperature. Select [CALIBRATE]
and press
OK
. Adjust to the proper value and press
OK
.
• Select [RESET] and press OK to reset the calibration.
• Without Pt1000, press CAL , adjust the manual temperature compensation and , adjust the manual temperature compensation and
proceed by pressing proceed by pressing OK .
mV measurement
1. Select the desired mode (mV) by pressing MODE. The display will immediately
show the measured value according to the previous calibration. Should you
want to recalibrate, press CAL .
2 . Immerse the electrodes in a standard solution of known potential. Select
[CALIBRATE] and press OK . Adjust to the proper value and press OK .
• Select [RESET] and press OK to reset the calibration.
• Hold MODE pressed and press MODE MODE
ê
to change the resolution from 1 to 0.1 mV.
Important
• A blinking decimal point warns you for unstable measurements. Wait to read
the display!
• Stirring the solution during the measurements promotes the homogeneity and
is obligatory!
• The instrument will refuse automatic calibration when the electrode is unsta-
ble. Insufficient stirring or a worn electrode may be the cause.
