Intended Use and General Overview

Thank you for purchasing a YSI portable automatic sampler. Samplers in the ProSample series are designed to collect
field samples and to provide temporary storage before they are analyzed in a laboratory.

The ProSample portable automatic samplers are designed for use in surface water, stormwater, and wastewater
applications. These samplers can be used in a variety of scenarios, most of which are described in this manual. If
you have a question regarding the use of a sampler in your project, please contact YSI (YSI.com/contact-us) or an
authorized YSI distributor.

There are four samplers in the ProSample series. Content in this user manual applies to all ProSample models unless
otherwise noted. ProSample models include:

• ProSample P: full-size portable sampler

• ProSample P-12: full-size portable sampler with SDI-12 connectivity

• ProSample PM: mini portable sampler

• ProSample PM-12: mini portable sampler with SDI-12 connectivity

Composite sampling can be completed with all ProSample models. In this type of sampling, a single container is used
to collect multiple samples, resulting in a mixture of all samples collected.

Discrete sampling can be completed with the ProSample P and ProSample P-12. In this type of sampling, samples are
placed in different bottles. There are several bottle configurations available for the purpose of discrete sampling.

All ProSample models have the following features:

• Robust PE, double-walled, insulated housing for temperature control.

• Easy tube replacement for minimal downtime.

• Spring-loaded roller bearings in the peristaltic pump providing long tubing life.

• Highly accurate sample volume using two capacitive sensors in the peristaltic pump for volume control.

• Simple programming and calibration.

• Long battery life.

• Non-volatile data memory for up to 5 years, so you never have to worry about losing your data if power is lost.

Charging the Battery

Initial Charge

The battery must be completely charged prior to first use. This should take approximately 14 to 16 hours.

NOTICE: A total discharge of the battery can result in damage to the battery. A protective mechanism built-in

which automatically switches off the device when the voltage is too low (9V or less). However, when
storing the battery long-term, regularly connect the battery to the charger to top off the charge, as this
will ensure the battery does not completely discharge.

NOTE: Please include the battery if the ProSample is returned to YSI for service — see the Technical Support

section on page 66 and the Service Information section on page 66.

To charge, connect a ProSample battery charger to the battery. Once the red light on the power supply turns to green,
the battery is fully charged and can be installed in the ProSample unit.

NOTE: There are three different battery chargers available for the ProSample. Please see the Replacement Parts

and Accessories section on page 60 for a list of available chargers.

Subsequent Charges

NOTE: When charging a new battery, it is recommended to use the steps in the Initial Charge section

on page 10.

The battery must always be installed in the ProSample when the sampler is in use, as the battery is the only way to
power the sampler. The ProSample will shut off when the battery drops below 9V.

There are two options for charging the battery that depend on access to mains (AC) power.

No Mains (AC) Power at Sampling Site

The battery can be periodically charged by removing it from the instrument and charging it with a ProSample battery
charger whenever a recharge is needed (see the Initial Charge section). This is most the common method of powering
the instrument when there is no mains (AC) power source located near the ProSample unit.

Mains (AC) Power Available at Sampling Site

It is also possible to keep the battery continuously connected to mains (AC) power. In this scenario, the battery is kept
installed in the instrument and an optional Y-cable (item # 0069810) is used to simultaneously connect the battery to
the battery charger and the instrument. This is the most common method of powering the instrument where there is
a mains (AC) power source located near the ProSample unit. Since the battery charger will typically be outdoors and/
or exposed to water, an IP-67 battery charger is recommended (see the Replacement Parts and Accessories section on
page 60).

NOTE: The battery must be completely charged prior to first use. It is recommended to initially charge the battery

by connecting the battery directly to the battery charger (i.e. the ‘Y’ cable is not used) – see the Initial

Charge section on page 10. The Y-cable can be used once the battery is initially charged.

For continuous connection of the battery to AC power via the Y-cable:

1. Open the instrument cover.

2. Disconnect the battery from the instrument.

3. Connect the Y-cable to the instrument.

4. Connect the Y-cable to the battery.

5. Connect the Y-cable to the battery charger.

Installing at a Sampling Site

The ProSample unit must be placed on a steady, level surface.

YSI recommends carefully planning out the installation location before drilling any holes, cutting any tubing, etc.

The ProSample should be installed in a location where the sample temperature is between 0 °C and 40 °C. The
sampler should not be exposed to explosive substances or an environment with an explosive atmosphere.

WARNING: If the unit is to be continuously connected to AC power, ensure the electrical supply is sufficiently

protected against short circuits.

Suction Hose Connection, Positioning, and Length

The suction hose is the hose that will transport water from the sampling site to the sampler. The other key consideration
when installing a ProSample unit is the correct positioning of the suction hose. One end of the suction hose connects
to the intermediate tube, while the other end of the suction hose is placed in the environment where samples are
collected.

INTERMEDIATE TUBE

SUCTION HOSE CONNECTION

SUCTION HOSE

Suction hose connection to the intermediate tube

NOTICE: The connectors on the ProSample intermediate tube and suction hose are ¾ inch-14BSPP. If not using

a YSI suction hose (5, 10, and 20 meter available), ensure the suction hose being used has a ¾ inch­14BSPP connection. A ¾ inch-14BSPP female connection (item # 630127) is available if the suction
hose being used does not have a ¾ inch-14BSPP connection.

There is a small gasket zip-tied to the suction hose upon delivery. Place this gasket in the suction hose connector
before connecting the suction hose to the intermediate tube. This gasket prevents air from getting in the line, thus
ensuring accurate dispensing of solution.

14

TO INTERMEDIATE TUBE

Installing at a Sampling Site

The suction hose cannot be longer than 30 meters. In addition, it should be positioned so it is descending in
elevation from the sampler to the sampling point. Locations marked with a red ‘X’ on the figure below are examples
where this requirement is not satisfied. Placing the hose in a PVC pipe can help ensure this requirement is met.

The hose should not be coiled, as this can allow water to collect in the excess hose and impede the travel of water
through the hose. If the suction hose is longer than needed, remove the sinker weight at the end of the suction hose,
cut the suction hose to the desired length, then reinstall the sinker weight.

Instrument Setup and Calibration

Installing the Peristaltic Pump Tube

The peristaltic pump tube does not come pre-installed in the ProSample. There are two peristaltic tubes included with
each ProSample — one can be found under the lid of the ProSample, while the other is in the top tray of the ProSample
packaging. To install the peristaltic pump tube:

1. Turn the ProSample OFF and disconnect the battery.

WARNING: Do NOT attempt to install a peristaltic pump tube or service the pump while the ProSample is ON.

The moving components of the pump can cause serious injury.

2. Use a flathead screw driver to loosen the bolt on the outside of the peristaltic pump cover.

3. There are two tube connectors the peristaltic pump tube will connect to — one connector is on the intermediate

tube while the other is on the composite sampling tube. Slide the connectors out of the side of the pump
housing.

4. Connect the peristaltic pump tube to each tube connector and slide the connectors back into the side of the

pump housing.

5. Place the peristaltic pump tube on the outside of the rollers of the peristaltic pump. You may need to turn the

roller assembly in order to get the pump tube to properly seat in the pump housing. Refer to the image below.

6. Close the battery cover to the peristaltic pump and tighten the bolt using a flathead screwdriver. Reconnect the

battery.

Pump Calibration

The peristaltic pump must be calibrated at each sampling site, as the length and gradient of the suction hose impact
the calibration result.

NOTE: Calibration in a lab setting can be completed to verify the instrument is functioning properly, but it is still

highly recommended to recalibrate the instrument once at the sampling site.

Calibration Containers

The ProSample is calibrated to an upper and lower volume, resulting in a 2-point calibration. The upper calibration
will dispense a large volume of solution, typically over 1000 mL, whereas the lower calibration will dispense a small
volume, around 250 mL.

The volume dispensed during calibration will need to be accurately measured. It is recommended to obtain a large,
plastic graduated cylinder and a small, plastic graduated cylinder when measuring the amount of solution dispensed
during calibration.

Calibration Procedure

The following steps describe how to calibrate the ProSample peristaltic pump:

1. Turn the ProSample OFF.

2. Remove the top of the ProSample housing and flip it over.

3. Remove the plastic ‘elbow’ piece from the end of the composite

sampling tube. There is a plastic bracket that keeps the
composite sampling tube in place during sampling – remove
the tube from this bracket.

4. Reinstall the top of the ProSample housing.

5. Pull the composite sampling tube out of the ProSample

housing. This will allow solution to be poured directly into a
graduated cylinder.

6. Place a graduated cylinder with a volume of at least 2000 mL

under the composite sampling tube.

5. Setup g System Settings g Pre purge

In order to clear the line of moisture and remove debris that
may have collected around the suction hose opening, the
peristaltic pump will push air through the suction hose before
a new sample is collected. Pre purge identifies the amount of
time air will be pushed through the suction hose.

The recommended Pre purge time depends on the length of
the suction hose. To identify the exact amount of Pre purge
time needed, set Pre purge to a relatively high value (e.g. 10
seconds). Once a Pre purge cycle starts, use a stopwatch to
determine how long it takes for air to be blown out of the
suction hose. This amount of time can then be entered for Pre
purge.

Programming

The ProSample can be used in a variety of scenarios that range from simple to complex. This programming section
reviews the most common sampling scenarios. Please contact YSI Technical Support if you would like to use the
ProSample in a sampling scenario that is not described in this manual.

NOTE: A complete review of the ProSample menu can be found in Appendix A: ProSample Menu Tree.

ProSample units with an SDI-12 input (ProSample P-12 and ProSample PM-12) can be used in all of the scenarios
described below, while ProSample units without an SDI-12 input (ProSample P and ProSample PM) can be used for all
scenarios expect SDI-12 parameter-driven sampling.

NOTE: The settings modified in the section Configure Key Instrument Settings on page 22 will be applied to each

and every program, so it is important these settings are carefully set before starting any program.

Sampling Scenario List and Descriptions

1. Stand-Alone Sampling: The ProSample will collect samples at a user-defined interval. All ProSample models can

be used for this sampling scenario. See page 28.

2. Analog Input Trigger: The ProSample will begin collecting samples when a 4-20 mA device (e.g. YSI Amazon

Bubbler or YSI IQSN sensor) meets user-defined sampling criteria. All ProSample models can be used for this
sampling scenario. See page 32.

3. Analog Input Volume-Modulation: The ProSample will begin collecting samples when a 4-20 mA device (e.g.

YSI Amazon Bubbler or YSI IQSN sensor) meets user-defined sampling criteria. The amount of sample collected
depends upon the 4-20 mA signal. All ProSample models can be used for this sampling scenario. See page 38.

4. Digital Pulse Input Trigger: The ProSample will trigger a program to start collecting samples when a digital pulse

is sent to the ProSample from a digital device, such as a data logger or digital flow meter. The ProSample P-12
and ProSample PM-12 can be used for this sampling scenario. See page 42.

5. Digital Pulse Input Event: The ProSample will take a sample each time it receives a digital pulse from a digital

device, such as a data logger or digital flow meter. All ProSample models can be used for this sampling

Stand-Alone Sampling

The ProSample will collect samples at a user-defined interval. All ProSample models can be used for this sampling
scenario. A flow signal cable and/or SDI-12 cable is not required to run this program.

NOTE: The settings modified in the section Configure Key Instrument Settings on page 22 will be applied to each

5. The Bottle Fill Time is displayed.

If using a composite bottle, Bottle Fill Time determines how
long the program will run. As an example, if Sampling Interval
is set to 15 minutes, Sample Volume is set to 100 mL, and Bottle
Fill Time is set to 2 hours, then the ProSample will collect 100
mL of sample every 15 minutes for 2 hours, resulting in a total
of 800 mL of sample collected.

If using discrete sampling bottles (i.e. more than one bottle is
used), Bottle Fill Time determines how many times each bottle
in the program will be filled. As an example, if Sampling Interval
is set to 15 minutes, Sample Volume is set to 100 mL, and
Bottle Fill Time is set to 15 minutes (i.e. the same as Sampling
Interval), then each bottle is only filled once and each bottle will
contain 100 mL of sample. The entire length of the program
is determined by the number of bottles that will be filled (see
steps # 5-7). Therefore, every 15 minutes a different bottle will
be filled. If there are 6 bottles, the entire program length will be
90 minutes.

As another example of discrete sampling, if Sampling Interval
is set to 15 minutes, Sample Volume is set to 100 mL, and
Bottle Fill Time is set to 45 minutes (i.e. three times longer than
Sampling Time), then each bottle is filled three times and each
bottle will contain 300 mL of sample

Analog Input Trigger

In this type of program, sampling will only occur when the trigger criteria are met. If the trigger criteria are no longer
met while the program is active, sampling will pause. Sampling will continue if and when the trigger criteria are met
again and will continue until the program is complete.

All ProSample models can be used for this sampling scenario. A flow signal cable (item # 630147) must be connected
to the analog device and the ProSample. As is shown in the Flow Signal Cable Wiring section on page 24, the brown
and white wires should be used when connecting the flow signal cable to the analog device.

As an example, if 10 mA is the High Setpoint and a Deadband
of 0.5 is entered, the mA signal must drop below 9.5 mA before
sampling no longer occurs.

If a Low Setpoint is entered, Deadband is the value which the

will collect a total of 8 samples in the composite bottle. The
amount collected will vary based on the mA signal at the time
of sampling (e.g. 500 mL collected at 20 mA and 0 mL collected
at 4 mA).

If using discrete sampling bottles (i.e. more than one bottle is
used), Var Fill Time determines how many times each bottle in
the program will be filled. As an example, if Sample Interval is
set to 15 minutes and Var Fill Time is set to 15 minutes (i.e. the
same as Sampling Interval), then each bottle is only filled once
and each bottle will contain a volume of sample that varies
based on the mA output at the time of sample collection. The
entire length of the program is determined by the number of

SDI-12 Parameter-Driven Sampling

In this sampling scenario, the ProSample will collect samples based upon measurements from an SDI-12 device (e.g.
YSI EXO3 sonde). This sampling scenario can only be completed with the ProSample P-12 and ProSample PM-12.
Please refer to the SDI-12 Cable Wiring section on page 26 when connecting the SDI-12 device to the ProSample.

In order to use an SDI-12 device, the user must configure it properly before programming the ProSample P-12 or
ProSample PM-12. As an example, if pH is a trigger parameter, the pH channel on the sonde and the ProSample must
be the same (e.g. channel 1). Please consult the user manual of your SDI-12 device regarding proper configuration.

Up to 4 SDI-12 parameters can be configured to trigger sampling. If there is a need for an AND scenario with multiple
parameters to trigger sampling (e.g. solution must have pH > 8 AND turbidity >124 FNU for sampling to begin), then a
data logger must be used to trigger sampling (see Digital Pulse Input Event on page 45).

There are two different methods of programming the sampler to stop sampling – continuous method and event
method. Steps # 9 and 12 in the following procedure determine which method is utilized.

Continuous method: If the trigger criteria are met, sampling will occur until the program is complete, even if the
trigger criteria are no longer met while the program is active. If more than one SDI-12 parameter is set to trigger
sampling, only the continuous method can be used.

Event method: Sampling will only occur when the trigger criteria are met. If the trigger criteria are no longer met while
the program is active, sampling will pause. Sampling will continue if and when the trigger criteria are met again and
will continue until the program is complete.

NOTE: The settings modified in the section Configure Key Instrument Settings on page 22 will be applied to each

and every program, so it is important these settings are carefully set before starting any program.

NOTE: Screenshots demonstrate an example setup. Settings should be adjusted for your specific application.

The following procedure should be followed for each SDI-12 parameter (up to 4) that will be used to trigger sampling.

NOTE: If using the continuous method, it is recommended to program the sampler (i.e. follow the procedure

below), place the SDI-12 device in the sampling environment, and then connect the SDI-12 device to the
ProSample P-12 or ProSample PM-12. This is recommended because the program is automatically started
if the trigger criteria are met (i.e. the program is not started by going to Program g Start).

4. Select the appropriate Unit for the channel that is being
configured and press the Enter key. In this example, pH is
configured to be the Channel 1 unit, as pH is configured to be
the channel 1 unit on the EXO3 sonde.

5. Select the Limit Channel to be used.

If a Low Setpoint is selected, any measurement value lower
than the Low Setpoint will trigger samples to be taken. As an
example, if a Low Setpoint of 6 is entered, then sampling will be
triggered once pH lowers to 6.

If a High Setpoint is selected, any measurement value higher
than the High Setpoint will trigger samples to be taken. As an
example, if a High Setpoint of 8 is entered, then sampling will
be triggered once pH increases to 8.

6. Enter the Setpoint value and press the Enter key.

7. The ProSample will request a Deadband be entered.

Deadband is important when using the Event method of
sampling, but Deadband is not relevant with the Continuous

method (any value can be entered since ProSample will
continue to run the program until completion).

If a High Setpoint is entered, Deadband is a value the selected
parameter must drop below before sampling no longer occurs
(Event method only). As an example, if pH 8 is the High Setpoint
and a Deadband of 0.5 is entered, the pH must drop below 7.5
before sampling no longer occurs.

If a Low Setpoint is entered, Deadband is the value the selected
parameter must rise above before sampling no longer occurs
(Event method only). As an example, if pH 6 is the Low Setpoint
and a Deadband of 0.5 is entered, the pH must rise above 6.5
before sampling no longer occurs.

Programming: SDI-12 Parameter Driven Sampling

13. The Bottle Fill Time is displayed.

If using a composite bottle, Bottle Fill Time determines how
long the program will run. As an example, if Sampling Interval
is set to 15 minutes, Sample Volume is set to 100 mL, and Bottle
Fill Time is set to 2 hours, then the ProSample will collect 100
mL of sample every 15 minutes for 2 hours, resulting in a total
of 800 mL of sample collected.

If using discrete sampling bottles (i.e. more than one bottle is
used), Bottle Fill Time determines how many times each bottle
in the program will be filled. As an example, if Sampling Interval
is set to 15 minutes, Sample Volume is set to 100 mL, and
Bottle Fill Time is set to 15 minutes (i.e. the same as Sampling
Interval), then each bottle is only filled once and each bottle will
contain 100 mL of sample. The entire length of the program
is determined by the number of bottles that will be filled (see
steps # 14-16). Therefore, every 15 minutes a different bottle
will be filled. If there are 6 bottles, the entire program length
will be 90 minutes.

As another example of discrete sampling, if Sampling Interval
is set to 15 minutes, Sample Volume is set to 100 mL, and
Bottle Fill Time is set to 45 minutes (i.e. three times longer than
Sampling Time), then each bottle is filled three times and each
bottle will contain 300 mL of sample

14. The Info screen is displayed.

If there is only one bottle installed (composite sampling):

• Select Settings Complete and the ProSample will return to
the Programs menu. Skip to step #18.

If there is a distributor arm and multiple bottles installed
(discrete sampling):

• Select More Settings g Bottle Selection.

t If you would like to fill all bottles in the sampler, select All
Bottles. Return to the More Settings menu by pressing the
Back key once, and then select Programming OK. Skip to
step #18.

t If you only want to fill certain bottles, select Bottle
Selection and continue with step #15.

15. First Bottle is displayed if the ProSample has more than one

bottle installed. Enter the bottle number in which the first
sample should be placed. Press the Enter key.

16. Last Bottle is displayed. Enter the bottle number in which the
last sample should be placed. Press the Enter key.

17. The More Settings menu is displayed. Highlight Programming
OK and press the Enter key. The Programs menu is displayed.

If using the continuous method, the program is automatically
started if the trigger criteria are met (i.e. the program is not
started by going to Program g Start), so there is no need
to continue with step # 18. Up to 3 other SDI-12 trigger
parameters can be configured by following steps # 1-17.

If using the event method, continue with step #18 below.

18. To run the program, highlight Start and press the Enter key.

NOTE: Ensure the instrument is calibrated before running any

programs. Please see the Pump Calibration on page 17.

19. Use the arrows to select the program to run. Press the Enter key.

Maintenance and Cleaning

Draining the Bottom Sampler Housing

On the ProSample P and ProSample P-12, there is a drain plug in the center of the bottom sampler housing. This drain
can be removed when cleaning the sampler housing, removing any spilled solution, or when draining any ice used to
keep collected samples cold.

Draining the ProSample P and ProSample P-12

Desiccant Replacement

A desiccant cartridge (40 % rel. humidity; item # 0060589) is located inside the ProSample controller to absorb
moisture and prevent corrosion. Over time the desiccant will become saturated with moisture and should be replaced.
Monitor the desiccant color through the clear plastic window. The color will change from blue to pink when the
desiccant is saturated.

54

Desiccant replacement

Maintenance and Cleaning

Peristaltic Pump Tube Replacement

Inspect and clean the pump tubing and rollers on a regular basis. Replace the pump tube (item # 0901062) when it has
become dirty or worn out. Cleaning and/or replacing the pump tube may also prove helpful if the ProSample displays
an error message during a program.

YSI does not have a recommended replacement interval for the peristaltic pump tube, as the lifetime of the tube
varies based on application. As an example, if the sampler is used at the outlet of a plant, the sampling environment is
likely relatively clean with little/no solids. However, if samples are collected at the inlet, the tube may have a very short
lifetime due to the amount of solids in solution. YSI recommends always having a spare peristaltic pump tube available.

NOTE: The inside of the pump tube can be cleaned with a sponge. Cut a 12x12 mm piece of sponge and go

to DIAGNOSTICS / TEST g COMPONENT TEST g PUMP. You can choose to run the pump forward
(suction) and backward (purging). Moisten the sponge, hold it to a tube end and let it “suck” through the
tube. It works in both directions. Repeat until the hose is clean again.

NOTICE: Use of tubing other than that supplied by the manufacturer may cause excessive wear on mechanical

parts and/or poor pump performance.

There is an extra pump tube included with each ProSample unit. It can be found inside the ProSample lid. Please refer
to Installing the Peristaltic Pump Tube on page 16 when replacing the peristaltic pump tube.

WARNING: Do NOT attempt to replace the peristaltic pump tube or service the pump while the ProSample

is ON. The moving components of the pump can cause serious injury.

Cleaning

The ProSample should be kept clean, especially the parts exposed to the sample such as the dosing unit, water
sensors, distributor, bottles and suction hose. Failure to do so could result in damage not covered by the warranty.

Clean the interior and exterior of the housing with a damp, lint-free cloth. Commercial household cleaner in water can
be used if needed.

Clean the unit around the distributor arm as required.

NOTICE: Do not manually rotate the distributor arm, as it can cause permanent damage to the drive. If you

need to move the arm, go to Diagnostics/Test g Component Test g Distributor. Enter the bottle
position you would like the arm to move to.

In addition to the peristaltic pump tube, also ensure the suction hose, distributor tube, and the intermediate tube are
clean. Replace if necessary.

Maintenance and Cleaning

55

Changing the Fuse(s)

If the ProSample is not operating as expected, it may be necessary to change one of the two fuses installed in the
ProSample – 8A and 2A. To remove the fuse, rotate as outlined in the picture below and pull out. Insert the replacement
fuse and tighten.

Removal of ProSample fuses

Long-Term Instrument Storage

To prepare the ProSample for long-term storage (e.g. over the winter):

1. Close all active programs.

2. Purge the peristaltic pump tube, intermediate tube, and
suction hose. From the Main Menu, go to Diagnostics/Test g
Component Test g Pump. Press the right arrow key to run the

pump backwards for purging. Keep the button pressed until all
tubes are empty.

3. Remove all liquids and, if necessary, solid matter from all tubes
and bottle compartments. Clean as needed.

4. Remove the peristaltic pump tube.

5. Remove the battery.

6. Store all items in a cool, dry place.

56

Maintenance and Cleaning

Factory Reset

A factory reset can reset all settings to the factory default. Please note that all setting and data will be deleted when
completing a factory reset. To complete a factory reset:

1. Turn OFF the ProSample.

2. Hold the power key and the Back key at the same time.

3. When the instrument beeps, release the power key but keep the Back key pressed.

4. Once the screen initializes and shows the “Load Factory Settings” page, release the Back key and allow the Pro-

Sample to boot.
