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. Immersed the probe to a depth at least 10 cm of the measured liquid in order for the probe to be influenced by the temperature & automatic temperature compensation to take place.

b. As for the thermal equilibrium to occur between the probe & the measurement sample must be allowed to pass, which usually amounts to a few minutes if the Temp. difference between the two is only several Celsius degrees.

5) a. In order to measure the dissolved oxygen content in any given liquid, it is sufficient to immerse the tip of the probe in the solution, making sure that velocity of the liquid coming into contact with the probe is at least 0.2 - 0.3 m/s or to shake the probe.

b. During laboratory measurements, the use of a magnetic agitator to ensure a certain velocity in the fluid is recommended. In this way, errors due to the diffusion of the oxygen present in the air in the solution are reduced to a minimum.

8 www.tmatlantic.com

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.

@

Press the " Function Button " once again, the Display unit will return to " mg/L ".

Change the Temp. unit to л

If intend to change the Temp. unit from к to л , please refer to chapter 8-7, page 25.

"% Salt" compensation value adjustment

If intend to change the % Salt compensation value, refer chapter 9-8, page 26.

"Height" compensation value adjustment

If intend to change the Height compensation value, refer to chapter 8-9, 8-10, page 26 page 27.

9 www.tmatlantic.com

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. 1 ) at the same time, the display will show the following screen as example, release the both fingers.

CAL

20.9

5) Press the " Enter Button " , the Display value will count from 30 to 0, then return to normal measuring screen and finish the calibration procedures. The complete calibration procedures will take 30 seconds approximately.

Press the " Function Button " ( 3-6, Fig. 1 ) once, to let Display unit to return " mg/L ".

Calibration Consideration : a. As the oxygen in air is 20.9 % typically, so use the environment air 02 value for quick & precise calibration.

b.Please process calibration procedures under wide and ventilating environment for best effect.

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 ). If yes, please fill the electrolyte or change the " Probe head with diaphragm set " and make the new calibration.

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.

11 www.tmatlantic.com

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

probe, should insert the " Probe head " into the " Probe protection cover "

( 4-5, Fig. 2 )

DC 9V Power Adapter ( optional ). Insert the plug of

Power Adapter into " DC 9V Power Adapter Input Socket

" ( 3-17, Fig. 1 ). The meter will permanent power ON when use the DC ADAPTER power supply ( The power

Button function is disable ).

10. BATTERY REPLACEMENT

1) When the left corner of LCD display show " ", it is necessary to replace the battery. However, in-spec.

measurement may still be made for several hours after low battery indicator appears before the instrument become inaccurate.

2) Loose the screws of the " Battery Cover " ( 3-10, Fig. 1 ) and take away the " Battery Cover " from the instrument and remove the battery.

3) Replace with DC 1.5 V battery ( UM3, AA,

Alkaline/heavy duty ) x 6 PCs, and reinstate the cover.

4) Make sure the battery cover is secured after changing batteries.

11. SYSTEM RESET

If the meter happen the troubles such as :

CPU system is hold ( for example, the key button can not be operated... ).

Then make the system RESET will fix the problem.

12. RS232 PC SERIAL INTERFACE

The instrument has RS232 PC serial interface via a 3.5

mm terminal ( 3-16, Fig. 1 ).

The data output is a 16 digit stream which can be utilized for user's specific application.

A RS232 lead with the following connection will be required to link the instrument with the PC serial port.

Meter PC

(9W 'D" Connector)

Center Pin..........................Pin 4

(3.5 mm jack plug)

Ground/shield.......................Pin 2
