QUICK REFERENCE INSTRUCTIONS
1.
Push and release the push button to turn the PT5 ON.
2.
While the LED flashes rapidly: Dip the pen in sample solution so the sensor is totally submerged.
3.
While the LED flashes slowly: Swirl the pen in sample, keeping sensor submerged.
4.
In HOLD mode – Real time readings are displayed until the LED turns solid ON. The display holds the final reading briefly then the PT5 turns OFF.
5.
In LIVE Mode – The PT5 will display constant, real time measurements for up to 5 minutes then turn OFF.

FEATURES
1. PUSH BUTTON
–Press to turn ON and select mode settings.
2. BATTERY CAP
–Unscrew to access battery for replacement.
3. DISPLAY
–Displays measurements, menu options, battery indicator,
etc.
4. LED INDICATOR LIGHT
–Tells the user when to dip & swirl the PT5
during measurements and calibrations.
5. DO SENSOR
–Measures dissolved oxygen (DO) in a solution.
6. MEMBRANE CAP
–Replaceable cap that contains the DO membrane.
7. THERMISTOR
–Measures temperature of water sample.
8. DO MEMBRANE
–Membrane is built into the membrane cap.
Use caution not to touch the membrane, as oil from your fingers will
compromise the membrane.
9. CAP STOP
–Shows how far to push the cap when putting it on the PT5.
CAUTION
:
DO NOT
push the hydration cap beyond the cap stop as
sensor damage may occur.
10. HYDRATION CAP
– Protects sensor and contains water vapor when
performing
AIR
calibrations. To remove, wiggle the cap back and forth
while pulling off. To replace, fill the cap with enough clean water
(preferably DI, RO, or distilled water) to soak the sponge inside. Wiggle
the cap back and forth while pushing on. Be careful, excess water may
squirt out.

SETUP AND MEASUREMENT INSTRUCTIONS
NOTES:
Selecting “ESC” from any menu immediately turns the PT5 OFF
without saving changes. Minimize bubbles in the sensor electrolyte to
improve accuracy.
I. SENSOR SETUP
1.
Remove the membrane cap from the sensor body by turning it in a
counter-clockwise direction. Use caution not to touch the membrane or
silver cathode with your fingers, as oil will compromise measurements.
2.
Install the syringe tip on the syringe and fill the syringe with DO
electrolyte solution.
3.
Holding the PT5 vertically with the DO sensor at the top, insert the
syringe tip into one of the four openings of the sensor body as far as it
can go inside the electrolyte well and fill the sensor to the top with
electrolyte.
•
Top off with more electrolyte after removing the syringe from the
sensor body.
4.
Pour some electrolyte inside the membrane cap to minimize air bubbles
that may occur when installing the cap.
5.
Holding the filled PT5 in one hand and the filled membrane cap in your
other hand, tilt the membrane cap and place it onto the sensor body.
6.
Carefully turn the membrane cap clockwise until it tightens firmly to the
sensor body. Some electrolyte may escape.
DO NOT
over tighten the
cap.
7.
Rinse any residual electrolyte from the outside of the sensor body with
clean water (DI, RO or distilled).
8.
Fill the hydration cap with enough clean water to soak the sponge
inside (preferably DI, RO, or distilled water).
9.
Push the hydration cap onto the DO Sensor by wiggling it back and
forth while pushing it on. Do not go beyond the Cap Stop.
10
. Let the sensor stabilize for 2-4 hours before using the PT5.
II. MEASUREMENT SETUP:
Prior to performing a measurement:
1.
Adjust the PT5 Altitude to match that of the measurement location.
2.
Adjust the PT5 Salinity to match that of the measurement solution.
3.
Perform a
ZERO
calibration followed by an
AIR
calibration.
III. ALTITUDE AND SALINITY ADJUSTMENT:
1.
Press and release the push button to turn the PT5 ON.
2.
Press and hold the push button to enter menu mode.
Altitude Adjustment:
Altitude is set in 100-foot increments
.
a.
Release the push button while “ALt SEL” is displayed.
b
. Press and release the push button repeatedly to slowly increase the
altitude, or push and hold the push button to quickly scroll. The
altitude selection will increase from -2000 to 15,000 feet, and then
repeat.
Salinity Adjustment:
Salinity is set in 1 ppt increments.
a.
Release the push button while “SAL SEL” is displayed.
b.
Press and release the push button repeatedly to slowly increase the
salinity, or push and hold the push button to quickly scroll. The
salinity will increase from 0 to 50 ppt, and then repeat.
3.
Release the push button and wait for the display to show “SAVEd”.
The new setting will be saved and the PT5 will turn OFF.
IV. ZERO CALIBRATION
1.
Prepare the PT5 for calibration by dipping the sensor in clean water
(preferably DI, RO, or purified water).
2.
Carefully blot the sensor membrane with a soft, clean, lint-free cloth or
tissue to remove any water drops.
3.
Pour the DO zero calibration solution, part # DOSOL, into a beaker or
cup.
4.
Completely submerge the sensor in zero calibration solution for 5
minutes.
5.
Keeping the sensor submerged in the zero calibration solution, press
and release the push button to turn the PT5 ON.
6.
Press and hold the push button. Release the push button while “CAL”
is displayed.
7.
Press and hold the push button. The display will alternate between the
following:
•
“0 CAL”; “Air CAL”; “H2O CAL”; “ESC”.
8.
Release the push button when “0 CAL” is displayed.
9.
The PT5 will perform the calibration, then display “SAVEd”, and turn
OFF.
10.
Verify the calibration by taking a measurement of the zero calibration
solution.
•
The result should be 0 ppm.
V. AIR CALIBRATION:
1.
Dip the DO sensor in clean water (preferably DI, RO, or distilled water).
2.
Carefully blot the DO sensor membrane with a soft, clean, lint-free cloth
or tissue to remove any water drops.
3.
Saturate the sponge of the hydration cap with clean water (preferably
DI, RO, or distilled water).
4.
Holding the PT5 vertically with the sensor side down, insert the sensor
into the hydration cap just enough to create a good seal (about
½
way
up the sensor body).
DO NOT
obstruct the vent hole in the hydration
cap.
5.
Push and release the push button to turn the PT5 ON.
