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 the measurement circuit may quantify its concentration.
1. Unscrew the "Probe head" (9-3, Fig 6).
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" (9-3, Fig 6) into the probe body.
When not use the probe, should insert the " Probe head "into
the " Probe protection cover "9-1 Probe handle( 8-5, Fig. 5 )

9. OTHER FUNCTION
9-1 Data Hold
During the measurement, press the "
Hold
Button" (3-3, Fig.1) once will hold the measured value & the
LCD will display a "
HOLD
" symbol. Press the "
Hold
Button" once again will release the data hold
function.
9-2 Data Record (Max., Min. reading)
1. The data record function records the maximum and minimum readings. Press the "
REC
Button " (3-4,
Fig.1) once to start the Data Record function and there will be a "
REC
. " symbol on the display..
2. With the "
REC
. " symbol on the display:
a.
Press the "
REC
Button" (3-4, Fig.1) once, the "
REC
. MAX." symbol along with the maximum value
will appear on the display. If intend to delete the maximum value, press the "Hold Button" (3-3, Fig.1)
once, then the display will show the "REC." symbol only & execute the memory function continuously.
b.
Press the "REC Button"(3-4, Fig.1) again, the "
REC
. MIN. " symbol along with the minimum value
will appear on the display. If intend to delete the minimum value, press the "
Hold
Button"( 3-3, Fig.1)
once, then the display will show the "REC." symbol only & execute the memory function continuously.
c.
To exit the memory record function, just press the "
REC
" button for 2 seconds at least. The display
will revert to the current reading.
9-3 LCD Backlight ON/OFF
After power ON, the "LCD Backlight" will light automatically. During the measurement, press the
"
Backlight
Button" (3-2, Fig.1) once will turn OFF the "LCD Backlight". Press the "
Backlight
Button"
once again will turn ON the "LCD Backlight" again.
