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.
1. Should you want to recalibrate, select the desired measurement and press
CAL. Follow the instructions on the screen. The displayed possibilities depend
on the channel set-up and selected measurement.
pH calibration:
2. Select the proper buffer from one of the values in memory or enter manually
a special value and press CAL. The unused buffers should be switched off.
3. Remove the electrodes from their fittings, rinse them with distilled water and
immerse them in the first buffer solution. Select [CALIBRATE], press CAL and
follow the instructions on the screen until the calibration is finished.
4. After rinsing the electrodes with distilled water, insert them back in their fit-
tings and start the control.
mV calibration:
2. Remove the electrodes from their fittings, rinse them with distilled water,
immerse them in a standard solution of known potential, adjust to the proper
value and press CAL.
3. After rinsing the electrodes with distilled water, insert them back in their fit-
tings and start the control.
Cl calibration:
2. Let the electrodes rest in the water stream for at least 24 hours (all dosing
systems switched off) before calibrating.
3. Measure the free chlorine acurately with a suitable photometer immediately
before calibration. Calibrate to the proper value and press CAL.
Temperature calibration:
1. Without Pt1000, adjust the manual temperature compensation and proceed by
pressing SET. Should you want to recalibrate, press CAL.
2. Immerse the Pt1000 in a standard solution of known temperature. Calibrate to
the proper value and press CAL.
Adjustment:
2. Measure the real value of the processed liquid with an other electrode and
meter. Adjust to the real value and press CAL. Press STOP here if you wish to
return to the original readings.
Press é to maximum measurement.
