Page Keypad 2. ESC used to switch the instrument on and to place into standby mode only if power supply lead remains connected to the instrument. This key is also used to clear readings from Memory. Ref Socket 2mm pin socket. Connection socket for separate reference electrode. When performing measurements with some pH and ion selective electrodes a separate reference electrode is needed.
Page 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 meter is supplied with a combination electrode. Page 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 Good Practice Guidelines 3. 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.
Any parameters not saved will remain as defaults or previous setting. 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. Symbol will flash while adjustment is being made.
Page 19 3. The data bits and parity will automatically adjust as the baud rate is selected. Page Ph Calibration 3. 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.
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.
Page 22 3. Page Error Codes 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. Page 24 3. Page Performing Measurements 3. If a separate reference electrode is to be used, this should be connected to the Ref socket.
Page Results Storage And Display 3. The memory location will be given on the status display. Up to 32 results can be stored. Each result will be stored in the next available memory location. It is only necessary to keep the external surfaces clean and free from dust. To give added protection when not in use the unit should be switched off and covered with the optional dust cover Page Optional Accessories Optional Accessories Optional Accessories Optional Accessories Optional Accessories The following list of items are available as optional accessories for use with the Model The following list of items are available as optional accessories for use with the Model 5.
Connect the printer via the cable supplied with the printer to the 9 way socket located on the rear panel of the instrument. Page 32 6.
