Page 12: Operation
If the liquid junction is inefficient then measurement will be inaccurate. It is common for the reference electrode to be incorporated into the pH electrode. It is then called a combination electrode. The Model 3510 meter is supplied with a combination electrode. 351 050/REV B/09-06... -
Page 13: Preparation Of Buffer Solution
The voltage developed by each individual pH electrode in the presence of a known hydrogen ion concentration is theoretically predictable, but in practise deviations from the theoretical value can be expected. These deviations will change slowly during the life of an electrode. It is therefore essential to routinely calibrate the system using solutions with a known and constant pH value. -
Page 14: Good Practice Guidelines
3.5 Good Practice Guidelines The types of electrodes are many and various. For the majority of tests carried out on aqueous solutions, with a reasonable ionic strength; at ambient temperatures and with limited use in strongly acidic or alkaline solutions, the standard glass or epoxy bodied combination electrode is ideal. For other applications a more suitable pH/reference electrode pair may be required;... -

MODE menu. Any parameters not saved will remain as defaults or previous setting. 3.6.1 Number of calibration points entry I, 2 or 3 point calibration is possible on the 3510. To set these parameters: Select SETUP mode on the display using the Left arrow key. - Page 16 The secondary display will show BUFFER and will then scroll BUFFER TYPE after 10 seconds. Select the type of buffer from the options available by scrolling through the list using the Up/Down arrows – AUTO, MAN, JIS, NIST or DIN. (AUTO relates to the Jenway buffer types supplied with the instrument).
- Page 17 If a 2 or 3 point calibration is being performed the display will move on to the 2 and then 3 point calibration buffer set up screens. The correct values should be entered and saved as for the 1 point calibration. When all chosen buffer types have been entered and confirmed the instrument display will update to show the next set up menu option.
- Page 18 3.6.4 Temperature units The display will show: The secondary display will show UNITS and will then scroll TEMPERATURE UNITS after 10 seconds. Select °C or °F using the Up/Down arrows. The Left/Right arrow keys and the CAL/CLR key have no function during this set up. Symbol will flash while adjustment is being made.

The display will show: The secondary display will show BAUD and will then scroll SERIAL PORT BAUD RATE after 10 seconds. Select the required baud rate (9600 or 1200) using the Up/Down arrow keys. The data bits and parity will automatically adjust as the baud rate is selected.

3.7 pH Calibration 3.7.1 Calibration with Manual Temperature Compensation To exit the calibration sequence at any time press the ESC key. This will cancel the pH calibration and return the instrument to the MODE menu. Note: Buffer solutions should be carefully prepared as per the manufacturers instructions. When using manual temperature compensation (no ATC probe fitted) the solution temperature should be measured and the value entered in the set up menu prior to calibrating the instrument (refer 3.6.5). - Page 21 If a successful calibration has been performed the secondary display will momentarily show CAL OK. The instrument will then update the display. The display will then show the next part of the calibration sequence if a 3 point calibration has been selected. If a 2 point calibration only is required the instrument will return to the main measuring screen.

4. CAL 3 Immerse the electrode(s) in the third buffer solution and allow the instrument to stabilise. When no change in the least significant display digit is detected over a five second period the endpoint symbol will be displayed. Press the CAL or STO key. If a successful I point calibration has been performed the secondary display will momentarily show CAL OK. - Page 24 3.9 Millivolt Mode Absolute Millivolts When this mode is selected the unit will display the actual voltage developed by the electrode when it is immersed in a solution containing ions to which the electrode is sensitive. The electrode may be a combination type or a suitable sensing/reference pair, depending on the specific test being carried out.

Page 25: Performing Measurements
3.10 Performing Measurements To perform measurements in pH, mV or temperature modes the following should be carried out: mV Measurement a) Connect the electrode to the unit via the BNC socket on the rear panel. If a separate reference electrode is to be used, this should be connected to the Ref socket. b) Select mV mode using the Up/Down arrows. -
