Page 7: Temperature Adjustment
±1000mV. Temperature Adjustment Model 430-020 is supplied with a temperature probe enabling automatic temperature compensation to be used. If the probe is disconnected then manual temperature compensation can be used instead. -
Page 8: Calibration And Measurement
Before performing a measurement the instrument must be calibrated. It is recommended that the instrument is calibrated daily to achieve consistent and accurate results. Model 430-020 has a 2 point calibration process. The first calibration point MUST be buffer pH 7.00. The second calibration point depends on the acidity of the solution which is to be measured. - Page 9 Temperature Meter 430-020 ‘FAIL’ will be shown if 7.00 pH buffer isn’t used as the first calibration point. If the electrode and buffer solution’s combined error is greater than 0.5 pH or 30mV then ‘Error I/P’ will be displayed and the calibration aborted. If the electrode and buffer solution’s combined error is greater than 30mV then...

Page 10: Care And Maintenance
Tris buffers, high temperatures and strongly acidic solutions a more suitable pH/reference electrode pair may be required. Details or advice are supplied on request at ele@eleint.co.uk. If the electrode readings are slow or erratic, place the electrode into cleaning solution or 7.00 pH solution for at least half an hour to one hour before... -
Page 11: Battery Replacement
Temperature Meter 430-020 DO NOT touch the sensitive glass pH membrane or reference junction. Excess droplets of solution may be removed by gently blotting with filter paper or tissue. DO NOT rub the electrode as this may induce an electrostatic charge. -
