Page 5: Calibration Of 'Ph'-Measurement
H33.0.01.6C-06 page 5 of 9 Calibration of 'pH'-Measurement The electrode data of pH-electrodes are subject to a lot of fluctuation due to ageing and manufacturing tolerances. Therefore, prior to taking measurements make it a rule to always check the current calibration with buffer solutions. If deviations are too large, a recalibration will be necessary. -
Page 6: Indication Of Electrode State (For Ph-Measurements Only)
H33.0.01.6C-06 page 6 of 9 Indication of Electrode State (for pH-Measurements only) The electrode state (will be calculated during each calibration) will be displayed for 3secs by pressing the -key or after each calibration. 100%: optimum electrode state 30...90%: satisfactory electrode state <30%: electrode considerably aged or soiled. -
Page 7: The Redox-Electrode
H33.0.01.6C-06 page 7 of 9 The pH-electrode pH-electrodes are wear parts which need to be replaced, depending on the chemical or mechanical stress they are subjected to, if the values required can no longer be kept even after thorough cleaning and recovery. Please take into account that there are several materials which attack glass when in watery solutions;... - Page 8 H33.0.01.6C-06 page 8 of 9 The Serial Interface All measuring and setting data of the device can be read or changed by means of the serial interfacee and a suitable electrically isolated interface adapter (GRS3100 or GRS3105). In order to avoid faulty transmission, we have gone to a lot of trouble to design security measures for this function.
