Use; Connection And Starting Up; Adjustments And Measurements Of The Ph; Manual Temperature Correction - Chauvin Arnoux PSD 1 Notice De Fonctionnement

3.1 CONNECTION AND STARTING UP

Unpack the instrument, the power supply unit and the operating manual.
Connect the pH electrode to the BNC connector on the back of the instrument.
Connect the power supply unit to the "power supply" connector.
(The PSD1 must be used only with the power supply unit provided).

3.2 ADJUSTMENTS AND MEASUREMENTS OF THE pH

3.2.1

MANUAL TEMPERATURE CORRECTION

Note the temperature of the sample to be analyzed.
Set the mark on the "Temperature" knob to the temperature of the medium to be
analyzed or of the buffer solution.
Remark: Ideally, the buffer solutions used to calibrate the measurement system
(pH meter-electrode) should be at this same temperature.

CALIBRATION AND ADJUSTMENT OF THE pH SCALE

3.2.2
3.2.2.1 Checks/precautions concerning the electrodes:
Before each pH measurement operation, make sure that:
the glass bulb of the electrode does not contain any air bubble,
the liquid electrolyte reference electrode is correctly filled with a
potassium chloride solution of the right concentration (KCl, 1 mol.L
the plug of the filling orifice of the reference electrode is open,
the electrode is correctly connected.
3.2.2.2 Calibration:
Example: Use of pH4 and pH7 buffer solutions.
Rinse the electrode in distilled water.
Immerse the electrode in the pH7 buffer solution (always first).
When the signal stabilizes, use the "Offset" knob to adjust the value
displayed to 7.00
Rinse the electrode in distilled water.
Immerse the electrode in a pH4 buffer solution.
