4. DO ( Dissolved Oxygen ) MEASURING and CALIBRATION PROCEDURE 4-1 Dissolved Oxygen measurement Fig. 2 1) Prepare the Oxygen Probe ( standard probe, DOPB-11 ), install the " Probe Plug " ( 4-1, Fig. 2 ) into the " DO Socket " ( 3-13, Fig. 1 ). 2) Power on the meter by pressing " Power Button " ( 3-2, Fig. 1 ) once.
Calibration at first ! If it is the first time to use the Dissolved Oxygen meter or after a certain period to use the meter again, then it should to execute the calibration procedures at the first. For the measurement precisely consideration, it recommend to make the calibration before each measurement. Calibration procedure, refer to chapter 4-2, page 10. 4) a.
6) Display will show the Dissolved Oxygen values ( mg/L ) at the same time the bottom display will show the Temp. value of the measured solution. 7) Rinsed the probe accurately with normal tap water after each series of measurement. Oxygen in the air During the DO measurement, press the " Function Button " ( 3-6, Fig. 1 ) once, the display unit will show " %O2 " instead of " mg/L " , it show the air Oxygen value for reference.
4-2 Calibration 1) Install the " Probe Plug " ( 4-1, Fig. 2 ) into the " DO Socket " ( 3-13, Fig. 1 ). 2) Power on the meter by pressing " Power Button " ( 3-2, Fig. 1 ) once. Press the " Function Button " ( 3-6, Fig. 1 ) once, to let Display unit will show " %O2 " instead of " mg/L ". 3) Wait for approx. 5 minutes at least until the display reading values become stable & no fluctuation. 4) Use the two fingers to press the " REC Button " ( 3-4, Fig 1 ) and HOLD Button " ( 3-3, Fig.
4-3 Probe maintenance User first time to use the meter Intend to let the DO probe keep the best condition, when user receive the Oxygen Probe, it should fill the Probe's Electrolyte at first. User already use the probe for a certain period : Whenever user can not calibrate the meter properly or the meter's reading value is not stable, please check the oxygen probe to see if the electrolyte in the probe head container is run out or the diaphragm ( probe head with diaphragm set) exist problem ( dirty ).
Probe-filling Electrolyte, OXEL-03 1) Unscrew the " Probe head " ( 5-3, Fig 3 ). 2) Pour out the old Electrolyte from the container of the " Probe head ". 3) Fill the new Electrolyte ( OXEL-03 ) into the container of the " Probe head " . 4) Screw the " Probe head " ( 5-3, Fig 3 ) into the probe body. 5) When not use the Fig. 3 probe, should insert the " Probe head " into the " Probe protection cover " 5-1 Probe handle ( 4-5, Fig. 2 ) 5-2 Temp.
