MEASURING PROCEDURE

5-1 Calibration
Before the measurement, it should make following calibration procedures first :

1. Connect the ” OXYGEN PROBE plug ” ( 4-6, Fig. 1 ) into the meter ( YK-2001PH ).
   Make sure that the probe lock switch should slide to the lock position (   ).

2. Power on the instrument.

3.  Push the ” O2 mg/L Button ( B Button ) ” ( 4-2, Fig. 1 ) to select the ” % O2″ function, the display will show the symbol of ” % O2″

4. Push the ” Zero Button ( C Button ) ” ( 4-3, Fig. 1 ) once, the LCD will show zero value then display the ” Air Oxygen ” value.

5.  Wait approx. 5 minutes at least until the display reading values become stable & no fluctuation.

• Push the ” CAL Button ( D Button ) ” ( 4-4, Fig. 1 ) then the display will show the values exact same as 20.9 or 20.8. (As the oxygen in air is 20.9 % typically, so use this data for quick & precise calibration).
  Consideration :
  Please make calibration procedures under wide and ventilating environment for best effect.
  5-2 Dissolved Oxygen(DO) measurement

  1. After the meter be calibrated ( above procedure 5-1 ), now the meter is ready for Dissolved Oxygen ( DO ) measurement.
  2. Push the ” O2 mg/L Button ( B Button ) ” ( 4-2, Fig. 1 ) to select the ” DO ” function, the display will show the symbol of ” mg/L ” .

5-3 Oxygen in Air(O2) measurement

1. After the meter be calibrated ( above procedure 5-1 ), now the meter is ready for O2measurement.
2. Push the ” O2 mg/L Button ( B Button ) ” ( 4-2, Fig. 1 ) to select the ” % O2″ function, the display will show the symbol of ” % O2″
3. The display will show the air oxygen in % values for reference.

5-4 Temperature measurement
During the measurement, the lower LCD Display will show the temperature values of measuring solution.
Push the ” / Button ” ( 4-1, Fig. 1 ) once will change ℃ ℉ the temperature display unit from ” to ” ℃ ℉ or ” to “.℉ ℃ 5-5 Other functions ( Hold, Memory, RS232…) Other functions, such as Data hold, Memory ( max., min., ), RS232 interface, Auto power off, Auto power off disable, please refer the operation manual of YK-2001PH.

PROBE MAINTENANCE

First time to use the meter :
Intend to let the DO probe keep the best condition, when user receive the DIGITAL OXYGEN METER along the PROBE, it should fill the Probe’s Electrolyte at first.
Already use the meter 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 ). If yes, please fill the electrolyte or change the ” Probe head with diaphragm set ” and make the new calibration ( refer chapter 5-1, page 5 ).
The consideration of Diaphragm ( probe head with diaphragm set) :
The oxygen probe component is the thin Teflon diaphragm housed in the tip of the probe. The diaphragm is permeable by the oxygen molecules but not by the considerably larger molecules contained in the electrolyte. Due to this characteristic, the oxygen may diffuse throughout the electrolyte solution contained in the probe, and its concentration may be quantified by the measurement circuit.
This sensitive diaphragm is rather delicate & is easily damaged if it comes into contact with solid objects or is subjected to blows. If the diaphragm is damaged ( dirty ) or the electrolyte is run out, it must be replaced in the following way :

1. Unscrew the ” Probe head ” ( 6-3, Fig 2 ).
2. Pour out the old Electrolyte from the container of the ” Probe head “. If the diaphragm is damaged ( dirty ), then change the new ” Probe head with diaphragm set “.
3. Fill the new Electrolyte ( OXEL-03 ) into the container of the ” Probe head ” .
4.  Screw the ” Probe head ” ( 6-3, Fig 2 ) into the probe body.
