Page 5: Sensor Installation
Electrodes must be installed vertically. The maximum angle to the vertical is 80°. The internal buffer must cover the inside surface of the membrane glass. Air bubbles in the membrane chamber must be removed by light shaking of the electrode in the vertical. APS-Z/APK-Z/ARS-Z K04/1122 page 5... -
Page 6: Calibration And Measuring
Then adjust the pH/redox value of the first buffer/test solution on the transmitter. Rinse off the pH electrode with deionized water and carefully dry it with a soft cloth. For redox electrodes the calibration is now complete page 6 APS-Z/APK-Z/ARS-Z K04/1122... - Page 7 The measuring instrument determines the zero point and slope of the sensor. Rinse off the electrode with deionized water and carefully dry it with a soft cloth. The calibration is complete. APS-Z/APK-Z/ARS-Z K04/1122 page 7...
