pH/mV/temperature measurement

All manuals and user guides at all-guides.com
pH measurement
1. Select the desired mode (pH) by pressing é ê . 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 + up to 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 instructions 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.
• 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 unstable.
Insufficient stirring or a worn electrode may be the cause.
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 electrode and press OK.
• Hold MODE pressed and press ê to change the resolution from 0.1 to 0.001 pH.
mV measurement
1. Select the desired mode (mV) by pressing é ê . 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 ê to change the resolution from 1 to 0.1 mV.
Temperature measurement
1. Select the desired mode (°C) by pressing é ê . Should you want to
recalibrate, 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
proceed by pressing OK.
rH measurement

1. After calibrating and rinsing the pH and redox electrodes with distilled water,
immerse them in the solution to be measured.
2. Select the multi-channel display by pressing é ê and read the display.
µW measurement
(C305x only)
1. After calibrating and rinsing the ORP and conductivity electrodes with
distilled water, immerse them in the solution to be measured.
2. Select the multi-channel display by pressing é ê and read the display.
