The measuring electrodes should be connected to the corresponding coaxial pH/
mV or EC/O
(C5030: mV2) connectors. Automatic temperature compensation and
2
temperature measurements are possible by plugging a Pt1000 temperature probe
into the °C terminals. You can also use an electrode with built-in Pt1000. Its
banana plugs should be inserted in the °C terminals. Without Pt1000, the manual
temperature compensation is automatically switched on.
•
Never immerse a pH electrode and an oxygen electrode together in the same
solution!
•
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.
ble. Insufficient stirring or a worn electrode may be the cause.
1. Select [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 display shows three of the 11 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). Select the proper buffers and
press CAL. The unused buffer should be switched off.
3. Rinse the electrodes with distilled water and immerse them in the first buffer
solution. Select [CALIBRATE], press CAL 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.
1. Select [mV] by pressing MODE. The display will immediately show the meas-
ured value according to the previous calibration (optional). Should you want
to recalibrate, press CAL.
2. Immerse the electrodes in a standard solution of known potential. Select
[CALIBRATE] and press CAL. Calibrate to the proper value and press CAL again
or press MODE to reset the factory settings.
3. Rinse the electrodes always with distilled water after use and store them in a
3...4 M KCl solution.
1. Select [rH
] by pressing MODE.

2. After rinsing the pH and redox electrodes with distilled water, immerse them
in the samples and read the display.
1. Select the desired range by pressing MODE.
2. Press CAL, select GLP and press CAL to display a complete cali bration report.
1. Press ê to store the displayed value in memory. The display shows a next stor-
age address.
2. Select the desired address and press CAL to enter the measured value in
memory.
1. Press é to recall the stored data. The display shows a list of stored values.
2. Select the desired address to read the stored values.
3. Press MODE to return to the normal measurements.
