Operation
Prepare the Electrode
The electrode is shipped “dry” and requires lling with the
supplied electrolyte solution before use. The membrane
should be in place and does not need replacement.
Follow the procedure at the end of this guide for lling the
bonded cap.
Powering the ExStik®
The ExStik® uses four (4) CR2032 Lithium Ion Batteries.
Press the ON/OFF button to turn the meter on or off. If the
batteries are weak, the ‘BAT’ indicator appears on the LCD.
The auto power off feature shuts the ExStik® off automati-
cally after approximately 10 minutes of inactivity. The auto
power off feature may be temporarily disabled for conve-
nience or for extended polarization time.
Startup Polarization Period
When the ExStik® is powered up for the rst time, the
electrode requires polarization. In order for this to occur
a three minute (approx.) polarization period must elapse
before measurements can be made. A special circuit is
included in this meter which, upon turn-on, maintains a
very small biasing current to the electrode for a period of
seven days. This keeps the electrode polarized and enables
the user to make immediate measurements (within a 7
day period) without waiting for the electrode to re-pola-
rize. Each time the ExStik® is turned on, the polarization
timer is reset and the 7 day polarization period is initiated.
A small asterisk at the bottom right corner of the display
is used to indicate that the polarization timer circuit is
active. If the ExStik is not used for more than seven day, a
3 minute waiting period is required before a measurement
can be made.
Turn-On Diagnostics
1. When the meter is turned ON the LCD displays “SELF”
and “CAL” while the meter runs a diagnostic routine.
2. During this time the meter is recalling the User Calibra-
tion data, performing self diagnostics & initializing the
ci rc ui tr y.
3. After this function is complete, the meter proceeds to
the normal measurement mode.
Measurements
1. Cover the electrode with the electrode cap. The sponge
contained in the cap should be moistened (not soaked)
with DI (distilled water) or clean tap water.
2. Pressing the ON/OFF button turns the meter ON or OFF.
When turned ON, the meter’s display switches on and
the Self Calibration utility runs (see above). The unit of
measure selected when the meter was last turned OFF
will remain on the display.
3. If this is the rst time the meter is powered up, wait ap-
prox. 3 minutes for the probe to polarize (please disable
auto-power off; Instructions for disabling auto-power off
are provided in a later section). For more details, please
read the Startup Polarization Period paragraph earlier in
this manual before continuing.
4. Select the desired units of measure by pressing and hol-
ding the MODE/HOLD button until the proper units are
shown in the display. Remove the electrode cover and
place the electrode in the sample to be measured. Stir
the electrode in the sample to remove any trapped air
bubbles from the membrane surface. Do not submerse
the electrode to the point that the sample liquid reaches
the meter’s electrode collar.
5. Allow the meter time to settle to the nal measurement
value.
Note: The larger the difference in temperature between
the electrode and the solution the longer it will take for
the reading to stabilize. Stabilization time can vary from
ten (10) seconds to ve (5) minutes.
Calibration
1. Calibration should be performed on a daily basis.
2. Turn the meter ON
3. Press and hold the MODE/HOLD button until % is dis-
played on the LCD.
4. If the meter has not been used for seven (7) days or
longer, allow the electrode to fully polarize. This may
take 2-3 minutes.
5. Place the electrode cap onto the electrode. The sponge
contained in the cap should be moistened (not soaked)
with DI (distilled water) or clean tap water. Be sure that
the electrode membrane is clean and dry or the cali-
bration will be incorrect. Never touch the membrane, as
skin oil will affect the electrode response.
6. Wait until the reading stabilizes then press and hold the
CAL/RECALL button until CAL is shown in the lower dis-
play. The readings will blink “101.7” and “SA” will appear.
7. When the calibration is complete “End” will appear and
then the meter will return to the normal measurement
mode.
Note: The “SA” will not appear if the calibration fails.
8. Optional ’zero oxygen’ calibration (improves measure-
ment accuracy for very low or very high DO measure-
ments): Place the electrode in a zero oxygen calibration
solution, such as 5% sodium sulte, wait for stability
and press the CAL/RECALL button until CAL is shown in
the in the lower display. Stability in a zero solution may
take many minutes, depending on electrode history.
Note: Sodium Sulte can become deposited on the
electrode and on the “coined” surface of the electrode
retaining collar. The presence of the Sodium Sulte will
negatively affect future DO measurements until such a
time where ALL of it is removed from the electrode.

Measurement and Display Considerations
• The DO600 uses a polarographic sensor, which consumes
oxygen at the sensing surface. This requires a con-
stant movement of the sample across the membrane to
maintain a constant dissolved oxygen level. It is recom-
mended that the probe be moved in the sample as the
measurement is made, or if in a laboratory environment,
the sample be stirred using a stir plate.
• If the unit appears to be locked (display frozen). It is
possible that the Data Hold mode has been inadvertently
accessed by a press of the MODE/HOLD button (HOLD
will be displayed in the bottom left of the LCD). Simply
press the MODE/HOLD button again or turn the meter off
and back on again.
• If the meter does latch up and no button presses revive
it, remove the batteries and restart.
• For maximum accuracy, allow sufcient time for the tem-
perature of the probe to reach the temperature of the
sample before taking a reading. This will be indicated by
a stable temperature reading on the display.
Maintenance

Vervanging van de elektrode
1. Om de elektrode te verwijderen, het instrument eerst uitschakelen (OFF) en
vervolgens de elektrodekraag losschroeven en verwijderen. (de kraag naar links
draaien om ze te verwijderen).
2. Schud de elektrode zachtjes heen en weer en trek ze naar beneden tot ze van de
meter loskomt.
3. Om een elektrode te bevestigen, de positionerende "sleutels" op de elektrode en de
behuizing van het hoofdlichaam in lijn brengen en de elektrode vervolgens zachtjes in
de meteraansluiting duwen tot ze goed vast zit.
4. De elektrodekraag voldoende vastmaken, zodat de elektrode goed op de meter
aangesloten is.
Electrode Replacement
1. To remove the electrode, rst turn the instrument OFF
and then unscrew and remove the electrode retaining
collar. (turn the collar counter-clockwise to remove).
2. Gently rock the electrode from side to side, pulling it
away from the meter until it disconnects.
3. To attach an electrode, align the positioning “keys” on
the electrode and the main body housing and then care-
fully push the electrode into the meter socket until it is
fully seated.
4. Tighten the electrode retaining collar rmly enough to
seal the electrode with the meter.
DO Bonded Membrane Cap replacement
Important Note : Do not touch the membrane as skin
oils will interfere with the oxygen permeability rate of the
membrane. Use caution when replacing the bonded cap.
1. It is recommended that the electrode remain attached
to the meter during this replacement process.
2. To remove the bonded cap from the electrode, unscrew
the cap rmly and carefully counter-clockwise from the
electrode (see diagram below).
3. Discard the used cap. Please Note: The installation of a
bonded cap causes the membrane to be tightly streched
over the cathode. Once a bonded cap is removed rein-
stallation is not possible as the membrane will no longer
be properly streched over the cathode.
4. Rinse the old electrolyte solution from the Cathode and
Anode before continuing.
5. Use the supplied Polishing Strips to clean, polish, shine,
and/or remove scratches from the cathode. Be sure to
moisten the cloth before polishing the cathode. Do not
over-polish the sensitive gold cathode.
6. Set the new replacement bonded cap on a at surface.
Leave the cap in this position throughout the replace-
ment process.
7. Fill the bonded cap with the electrolyte solution up to
the bottom of the threads on the inside of the cap.
8. Tap the side of the bonded cap to help jar free any
trapped air bubbles from the electrolyte solution.
9. Keeping the cap in a xed position on a at surface,
carefully insert the electrode into the new bonded cap
by rst dipping and removing the electrode several
times from the cap. With each dip, push the electrode
progressively deeper into the bonded cap. Finally, screw
the electrode slowly onto the bonded cap (clockwise)
until fully tightened. The dipping and removal tech-
nique minimizes the introduction of air bubbles into the
electrolyte solution. Air bubbles in the electrolyte can
compromise measurements.
10. During the tightening of the bonded cap, excess elec-
trolyte solution will leak out, this is normal and desire-
able since it minimizes the introduction of air pockets.
Clean off the excess electrolyte before use.

DO Bonded Membrane Cap replacement
Important Note : Do not touch the membrane as skin oils will interfere with the oxygen
permeability rate of the membrane. Use caution when replacing the bonded cap.
1. It is recommended that the electrode remain attached to the meter during this
replacement process.
2. To remove the bonded cap from the electrode, unscrew the cap firmly and carefully
counter-clockwise from the electrode (see diagram below).
3. Discard the used cap. Please Note: The installation of a bonded cap causes the
membrane to be tightly streched over the cathode. Once a bonded cap is removed
reinstallation is not possible as the membrane will no longer be properly streched
over the cathode.
4. Rinse the old electrolyte solution from the Cathode and Anode before continuing.
5. Use the supplied Polishing Strips to clean, polish, shine, and/or remove scratches
from the cathode. Be sure to moisten the cloth before polishing the cathode. Do not
over-polish the sensitive gold cathode.
6. Set the new replacement bonded cap on a flat surface. Leave the cap in this position
throughout the replacement process.
7. Fill the bonded cap with the electrolyte solution up to the bottom of the threads on the
inside of the cap.
8. Tap the side of the bonded cap to help jar free any trapped air bubbles from the
electrolyte solution.
9. Keeping the cap in a fixed position on a flat surface, carefully insert the electrode into
the new bonded cap by first dipping and removing the electrode several times from
the cap. With each dip, push the electrode progressively deeper into the bonded cap.
Finally, screw the electrode slowly onto the bonded cap (clockwise) until fully
