calibration sleeve and then immersed in the measured water for about 10 minutes, then re-calibrate the meter. The electrode polarization and calibration must be performed every time when the instrument is turned on. 5.3 DO Calibration 5.3.1 Steps for DO calibration a) Press to turn on the meter, press to choose the units: mg/L (ppm) and %. -

out the polishing paper from the accessories and polish the surface of the gold chip at cathode, wipe it with clean flannel or tissue paper, rinse the electrode with pure water and allow it to dry. Add some electrolyte into the membrane cap, screw it on tightly and then perform full saturation and zero oxygen calibration, follow the steps of 5.3.1 and 5.4.1. -
Page 10: Notes Of The Measurement
5.5.2 Measurement in field a) Measurement in flow water (water velocity>5cm/s): immerse the dissolved oxygen electrode into the water, the water surface should exceed the position of the temperature sensor. The direction of the electrode and the water flow is 45°~75°, stir gently for 3~5 minutes and then get the reading after the reading is stable. -
