When the physical value on the display becomes stable you can save the reference value with OK IMPORTANT Should the actual measured voltage strongly dif fer from the design zero point of the electrode it means there is a zero point drift of the electrode This should not exceed the specifications of the DIN Standards 19265 In the event of zero point drift exceeding 40 mV TOPAX DE warns you about possible bad prove calibration Buffer 2 Transconductance calibration Clean the single rod measuring cell before calibrating the transconduct ance flush out with distilled water ATTENTION Avoid rubbing off glass electrodes as this will pro duce a static charge on the electrode This would result in faulty readings For transconductance calibration a buffer solution must be used which differs at least 2 pH units from the zero point For transconductance cali bration the manufacturer offers a buffer solution of pH 9 27 Should you use a different buffer solution for calibration of the resistivity you first need to set TOPAX DE to the pH of your other solution When soaking the Ph electrode in this buffer solution Ph 9 27 a voltage of 134 mV should be displayed on the TOPAX DE The physical value actu ally measured however always differs from the theoretical one Confirm presetting by pressing OK The transconductance value of the single rod measuring cell is then displayed In accordance with DIN 19265 the
